>gnl|CDD|187622 cd05364, SDR_c11, classical (c) SDR, subgroup 11. SDRs are a
functionally diverse family of oxidoreductases that have
a single domain with a structurally conserved Rossmann
fold (alpha/beta folding pattern with a central
beta-sheet), an NAD(P)(H)-binding region, and a
structurally diverse C-terminal region. Classical SDRs
are typically about 250 residues long, while extended
SDRs are approximately 350 residues. Sequence identity
between different SDR enzymes are typically in the
15-30% range, but the enzymes share the Rossmann fold
NAD-binding motif and characteristic NAD-binding and
catalytic sequence patterns. These enzymes catalyze a
wide range of activities including the metabolism of
steroids, cofactors, carbohydrates, lipids, aromatic
compounds, and amino acids, and act in redox sensing.
Classical SDRs have an TGXXX[AG]XG cofactor binding
motif and a YXXXK active site motif, with the Tyr
residue of the active site motif serving as a critical
catalytic residue (Tyr-151, human
15-hydroxyprostaglandin dehydrogenase (15-PGDH)
numbering). In addition to the Tyr and Lys, there is
often an upstream Ser (Ser-138, 15-PGDH numbering)
and/or an Asn (Asn-107, 15-PGDH numbering) contributing
to the active site; while substrate binding is in the
C-terminal region, which determines specificity. The
standard reaction mechanism is a 4-pro-S hydride
transfer and proton relay involving the conserved Tyr
and Lys, a water molecule stabilized by Asn, and
nicotinamide. Extended SDRs have additional elements in
the C-terminal region, and typically have a TGXXGXXG
cofactor binding motif. Complex (multidomain) SDRs such
as ketoreductase domains of fatty acid synthase have a
GGXGXXG NAD(P)-binding motif and an altered active site
motif (YXXXN). Fungal type ketoacyl reductases have a
TGXXXGX(1-2)G NAD(P)-binding motif. Some atypical SDRs
have lost catalytic activity and/or have an unusual
NAD(P)-binding motif and missing or unusual active site
residues. Reactions catalyzed within the SDR family
include isomerization, decarboxylation, epimerization,
C=N bond reduction, dehydratase activity,
dehalogenation, Enoyl-CoA reduction, and
carbonyl-alcohol oxidoreduction.

TR-II)-like, classical (c) SDRs. This subgroup includes
TR-I and TR-II; these proteins are members of the SDR
family. TRs catalyze the NADPH-dependent reductions of
the 3-carbonyl group of tropinone, to a beta-hydroxyl
group. TR-I and TR-II produce different stereoisomers
from tropinone, TR-I produces tropine
(3alpha-hydroxytropane), and TR-II, produces
pseudotropine (sigma-tropine, 3beta-hydroxytropane).

>gnl|CDD|187594 cd05333, BKR_SDR_c, beta-Keto acyl carrier protein reductase (BKR),
involved in Type II FAS, classical (c) SDRs. This
subgroup includes the Escherichai coli K12 BKR, FabG.
BKR catalyzes the NADPH-dependent reduction of ACP in
the first reductive step of de novo fatty acid synthesis
(FAS). FAS consists of four elongation steps, which are
repeated to extend the fatty acid chain through the
addition of two-carbo units from malonyl acyl-carrier
protein (ACP): condensation, reduction, dehydration, and
a final reduction. Type II FAS, typical of plants and
many bacteria, maintains these activities on discrete
polypeptides, while type I FAS utilizes one or two
multifunctional polypeptides. BKR resembles enoyl
reductase, which catalyzes the second reduction step in
FAS. SDRs are a functionally diverse family of
oxidoreductases that have a single domain with
structurally conserved Rossmann fold (alpha/beta folding
pattern with a central beta-sheet) NAD(P)(H) binding
region and a structurally diverse C-terminal region.
Classical SDRs are typically about 250 residues long,
while extended SDRS are approximately 350 residues.
Sequence identity between different SDR enzymes are
typically in the 15-30% range, but the enzymes share the
Rossmann fold NAD binding motif and characteristic
NAD-binding and catalytic sequence patterns. These
enzymes have a 3-glycine N-terminal NAD(P)(H) binding
pattern: TGxxxGxG in classical SDRs. Extended SDRs have
additional elements in the C-terminal region, and
typically have a TGXXGXXG cofactor binding motif.
Complex (multidomain) SDRs such as ketoreductase domains
of fatty acid synthase have a GGXGXXG NAD(P) binding
motif and an altered active site motif (YXXXN). Fungal
type type ketoacyl reductases have a TGXXXGX(1-2)G
NAD(P)-binding motif. Some atypical SDRs have lost
catalytic activity and/or have an unusual NAD(P) binding
motif and missing or unusual active site residues.
Reactions catalyzed within the SDR family include
isomerization, decarboxylation, epimerization, C=N bond
reduction, dehydratase activity, dehalogenation,
Enoyl-CoA reduction, and carbonyl-alcohol
oxidoreduction. A critical catalytic Tyr residue
(Tyr-151, human 15-hydroxyprostaglandin dehydrogenase
(15-PGDH) numbering), is often found in a conserved
YXXXK pattern. In addition to the Tyr and Lys, there is
often an upstream Ser (Ser-138, 15-PGDH numbering)
and/or an Asn (Asn-107, 15-PGDH numbering) or additional
Ser, contributing to the active site. Substrates for
these enzymes include sugars, steroids, alcohols, and
aromatic compounds. The standard reaction mechanism is a
proton relay involving the conserved Tyr-151 and
Lys-155, and well as Asn-111 (or Ser). Some SDR family
members, including 17 beta-hydroxysteroid dehydrogenase
contain an additional helix-turn-helix motif that is not
generally found among SDRs.

tetrahydroxynaphthalene/trihydroxynaphthalene
reductase-like, classical (c) SDRs.
1,3,6,8-tetrahydroxynaphthalene reductase (4HNR) of
Magnaporthe grisea and the related
1,3,8-trihydroxynaphthalene reductase (3HNR) are typical
members of the SDR family containing the canonical
glycine rich NAD(P)-binding site and active site tetrad,
and function in fungal melanin biosynthesis. This
subgroup also includes an SDR from Norway spruce that
may function to protect against both biotic and abitoic
stress. SDRs are a functionally diverse family of
oxidoreductases that have a single domain with a
structurally conserved Rossmann fold (alpha/beta folding
pattern with a central beta-sheet), an NAD(P)(H)-binding
region, and a structurally diverse C-terminal region.
Classical SDRs are typically about 250 residues long,
while extended SDRs are approximately 350 residues.
Sequence identity between different SDR enzymes are
typically in the 15-30% range, but the enzymes share the
Rossmann fold NAD-binding motif and characteristic
NAD-binding and catalytic sequence patterns. These
enzymes catalyze a wide range of activities including
the metabolism of steroids, cofactors, carbohydrates,
lipids, aromatic compounds, and amino acids, and act in
redox sensing. Classical SDRs have an TGXXX[AG]XG
cofactor binding motif and a YXXXK active site motif,
with the Tyr residue of the active site motif serving as
a critical catalytic residue (Tyr-151, human
15-hydroxyprostaglandin dehydrogenase (15-PGDH)
numbering). In addition to the Tyr and Lys, there is
often an upstream Ser (Ser-138, 15-PGDH numbering)
and/or an Asn (Asn-107, 15-PGDH numbering) contributing
to the active site; while substrate binding is in the
C-terminal region, which determines specificity. The
standard reaction mechanism is a 4-pro-S hydride
transfer and proton relay involving the conserved Tyr
and Lys, a water molecule stabilized by Asn, and
nicotinamide. Extended SDRs have additional elements in
the C-terminal region, and typically have a TGXXGXXG
cofactor binding motif. Complex (multidomain) SDRs such
as ketoreductase domains of fatty acid synthase have a
GGXGXXG NAD(P)-binding motif and an altered active site
motif (YXXXN). Fungal type ketoacyl reductases have a
TGXXXGX(1-2)G NAD(P)-binding motif. Some atypical SDRs
have lost catalytic activity and/or have an unusual
NAD(P)-binding motif and missing or unusual active site
residues. Reactions catalyzed within the SDR family
include isomerization, decarboxylation, epimerization,
C=N bond reduction, dehydratase activity,
dehalogenation, Enoyl-CoA reduction, and
carbonyl-alcohol oxidoreduction.

>gnl|CDD|187616 cd05358, GlcDH_SDR_c, glucose 1 dehydrogenase (GlcDH), classical
(c) SDRs. GlcDH, is a tetrameric member of the SDR
family, it catalyzes the NAD(P)-dependent oxidation of
beta-D-glucose to D-glucono-delta-lactone. GlcDH has a
typical NAD-binding site glycine-rich pattern as well as
the canonical active site tetrad (YXXXK motif plus
upstream Ser and Asn). SDRs are a functionally diverse
family of oxidoreductases that have a single domain with
a structurally conserved Rossmann fold (alpha/beta
folding pattern with a central beta-sheet), an
NAD(P)(H)-binding region, and a structurally diverse
C-terminal region. Classical SDRs are typically about
250 residues long, while extended SDRS are approximately
350 residues. Sequence identity between different SDR
enzymes are typically in the 15-30% range, but the
enzymes share the Rossmann fold NAD-binding motif and
characteristic NAD-binding and catalytic sequence
patterns. These enzymes have a 3-glycine N-terminal
NAD(P)(H)-binding pattern (typically, TGxxxGxG in
classical SDRs and TGxxGxxG in extended SDRs), while
substrate binding is in the C-terminal region. A
critical catalytic Tyr residue (Tyr-151, human
15-hydroxyprostaglandin dehydrogenase (15-PGDH)
numbering), is often found in a conserved YXXXK pattern.
In addition to the Tyr and Lys, there is often an
upstream Ser (Ser-138, 15-PGDH numbering) and/or an Asn
(Asn-107, 15-PGDH numbering) or additional Ser,
contributing to the active site. Substrates for these
enzymes include sugars, steroids, alcohols, and aromatic
compounds. The standard reaction mechanism is a proton
relay involving the conserved Tyr and Lys, as well as
Asn (or Ser). Some SDR family members, including 17
beta-hydroxysteroid dehydrogenase contain an additional
helix-turn-helix motif that is not generally found among
SDRs.

17beta-hydroxysteroid dehydrogenases are a group of
isozymes that catalyze activation and inactivation of
estrogen and androgens. SDRs are a functionally diverse
family of oxidoreductases that have a single domain with
a structurally conserved Rossmann fold (alpha/beta
folding pattern with a central beta-sheet), an
NAD(P)(H)-binding region, and a structurally diverse
C-terminal region. Classical SDRs are typically about
250 residues long, while extended SDRs are approximately
350 residues. Sequence identity between different SDR
enzymes are typically in the 15-30% range, but the
enzymes share the Rossmann fold NAD-binding motif and
characteristic NAD-binding and catalytic sequence
patterns. These enzymes catalyze a wide range of
activities including the metabolism of steroids,
cofactors, carbohydrates, lipids, aromatic compounds,
and amino acids, and act in redox sensing. Classical
SDRs have an TGXXX[AG]XG cofactor binding motif and a
YXXXK active site motif, with the Tyr residue of the
active site motif serving as a critical catalytic
residue (Tyr-151, human 15-hydroxyprostaglandin
dehydrogenase (15-PGDH) numbering). In addition to the
Tyr and Lys, there is often an upstream Ser (Ser-138,
15-PGDH numbering) and/or an Asn (Asn-107, 15-PGDH
numbering) contributing to the active site; while
substrate binding is in the C-terminal region, which
determines specificity. The standard reaction mechanism
is a 4-pro-S hydride transfer and proton relay involving
the conserved Tyr and Lys, a water molecule stabilized
by Asn, and nicotinamide. Extended SDRs have additional
elements in the C-terminal region, and typically have a
TGXXGXXG cofactor binding motif. Complex (multidomain)
SDRs such as ketoreductase domains of fatty acid
synthase have a GGXGXXG NAD(P)-binding motif and an
altered active site motif (YXXXN). Fungal type ketoacyl
reductases have a TGXXXGX(1-2)G NAD(P)-binding motif.
Some atypical SDRs have lost catalytic activity and/or
have an unusual NAD(P)-binding motif and missing or
unusual active site residues. Reactions catalyzed within
the SDR family include isomerization, decarboxylation,
epimerization, C=N bond reduction, dehydratase activity,
dehalogenation, Enoyl-CoA reduction, and
carbonyl-alcohol oxidoreduction.

15-hydroxyprostaglandin dehydrogenase (15-PGDH)
numbering). In addition to the Tyr and Lys, there is
often an upstream Ser (Ser-138, 15-PGDH numbering)
and/or an Asn (Asn-107, 15-PGDH numbering) contributing
to the active site; while substrate binding is in the
C-terminal region, which determines specificity. The
standard reaction mechanism is a 4-pro-S hydride
transfer and proton relay involving the conserved Tyr
and Lys, a water molecule stabilized by Asn, and
nicotinamide. Extended SDRs have additional elements in
the C-terminal region, and typically have a TGXXGXXG
cofactor binding motif. Complex (multidomain) SDRs such
as ketoreductase domains of fatty acid synthase have a
GGXGXXG NAD(P)-binding motif and an altered active site
motif (YXXXN). Fungal type ketoacyl reductases have a
TGXXXGX(1-2)G NAD(P)-binding motif. Some atypical SDRs
have lost catalytic activity and/or have an unusual
NAD(P)-binding motif and missing or unusual active site
residues. Reactions catalyzed within the SDR family
include isomerization, decarboxylation, epimerization,
C=N bond reduction, dehydratase activity,
dehalogenation, Enoyl-CoA reduction, and
carbonyl-alcohol oxidoreduction.

>gnl|CDD|187648 cd08944, SDR_c12, classical (c) SDR, subgroup 12. These are
classical SDRs, with the canonical active site tetrad
and glycine-rich NAD-binding motif. SDRs are a
functionally diverse family of oxidoreductases that have
a single domain with a structurally conserved Rossmann
fold (alpha/beta folding pattern with a central
beta-sheet), an NAD(P)(H)-binding region, and a
structurally diverse C-terminal region. Classical SDRs
are typically about 250 residues long, while extended
SDRs are approximately 350 residues. Sequence identity
between different SDR enzymes are typically in the
15-30% range, but the enzymes share the Rossmann fold
NAD-binding motif and characteristic NAD-binding and
catalytic sequence patterns. These enzymes catalyze a
wide range of activities including the metabolism of
steroids, cofactors, carbohydrates, lipids, aromatic
compounds, and amino acids, and act in redox sensing.
Classical SDRs have an TGXXX[AG]XG cofactor binding
motif and a YXXXK active site motif, with the Tyr

>gnl|CDD|187603 cd05345, BKR_3_SDR_c, putative beta-ketoacyl acyl carrier protein
[ACP] reductase (BKR), subgroup 3, classical (c) SDR.
This subgroup includes the putative Brucella melitensis
biovar Abortus 2308 BKR, FabG, Mesorhizobium loti
MAFF303099 FabG, and other classical SDRs. BKR, a member
of the SDR family, catalyzes the NADPH-dependent
reduction of acyl carrier protein in the first reductive
step of de novo fatty acid synthesis (FAS). FAS
consists of 4 elongation steps, which are repeated to
extend the fatty acid chain thru the addition of
two-carbo units from malonyl acyl-carrier protein (ACP):
condensation, reduction, dehydration, and final
reduction. Type II FAS, typical of plants and many
bacteria, maintains these activities on discrete
polypeptides, while type I Fas utilizes one or 2
multifunctional polypeptides. BKR resembles enoyl
reductase, which catalyzes the second reduction step in
FAS. SDRs are a functionally diverse family of
oxidoreductases that have a single domain with a
structurally conserved Rossmann fold (alpha/beta folding
pattern with a central beta-sheet), an NAD(P)(H)-binding
region, and a structurally diverse C-terminal region.
Classical SDRs are typically about 250 residues long,
while extended SDRS are approximately 350 residues.
Sequence identity between different SDR enzymes are
typically in the 15-30% range, but the enzymes share the
Rossmann fold NAD-binding motif and characteristic
NAD-binding and catalytic sequence patterns. These
enzymes have a 3-glycine N-terminal NAD(P)(H)-binding
pattern (typically, TGxxxGxG in classical SDRs and
TGxxGxxG in extended SDRs), while substrate binding is
in the C-terminal region. A critical catalytic Tyr
residue (Tyr-151, human 15-hydroxyprostaglandin
dehydrogenase (15-PGDH) numbering), is often found in a
conserved YXXXK pattern. In addition to the Tyr and Lys,
there is often an upstream Ser (Ser-138, 15-PGDH
numbering) and/or an Asn (Asn-107, 15-PGDH numbering) or
additional Ser, contributing to the active site.
Substrates for these enzymes include sugars, steroids,
alcohols, and aromatic compounds. The standard reaction
mechanism is a proton relay involving the conserved Tyr
and Lys, as well as Asn (or Ser). Some SDR family
members, including 17 beta-hydroxysteroid dehydrogenase
contain an additional helix-turn-helix motif that is not
generally found among SDRs.

>gnl|CDD|187627 cd05369, TER_DECR_SDR_a, Trans-2-enoyl-CoA reductase (TER) and
2,4-dienoyl-CoA reductase (DECR), atypical (a) SDR.
TTER is a peroxisomal protein with a proposed role in
fatty acid elongation. Fatty acid synthesis is known to
occur in the both endoplasmic reticulum and
mitochondria; peroxisomal TER has been proposed as an
additional fatty acid elongation system, it reduces the
double bond at C-2 as the last step of elongation. This
system resembles the mitochondrial system in that
acetyl-CoA is used as a carbon donor. TER may also
function in phytol metabolism, reducting phytenoyl-CoA
to phytanoyl-CoA in peroxisomes. DECR processes double
bonds in fatty acids to increase their utility in fatty
acid metabolism; it reduces 2,4-dienoyl-CoA to an
enoyl-CoA. DECR is active in mitochondria and
peroxisomes. This subgroup has the Gly-rich NAD-binding
motif of the classical SDR family, but does not display
strong identity to the canonical active site tetrad, and
lacks the characteristic Tyr at the usual position. SDRs
are a functionally diverse family of oxidoreductases
that have a single domain with a structurally conserved
Rossmann fold (alpha/beta folding pattern with a central
beta-sheet), an NAD(P)(H)-binding region, and a
structurally diverse C-terminal region. Classical SDRs
are typically about 250 residues long, while extended
SDRS are approximately 350 residues. Sequence identity
between different SDR enzymes are typically in the
15-30% range, but the enzymes share the Rossmann fold
NAD-binding motif and characteristic NAD-binding and
catalytic sequence patterns. These enzymes have a
3-glycine N-terminal NAD(P)(H)-binding pattern
(typically, TGxxxGxG in classical SDRs and TGxxGxxG in
extended SDRs), while substrate binding is in the
C-terminal region. A critical catalytic Tyr residue
(Tyr-151, human 15-hydroxyprostaglandin dehydrogenase
(15-PGDH) numbering), is often found in a conserved
YXXXK pattern. In addition to the Tyr and Lys, there is
often an upstream Ser (Ser-138, 15-PGDH numbering)
and/or an Asn (Asn-107, 15-PGDH numbering) or additional
Ser, contributing to the active site. Substrates for
these enzymes include sugars, steroids, alcohols, and
aromatic compounds. The standard reaction mechanism is a
proton relay involving the conserved Tyr and Lys, as
well as Asn (or Ser). Some SDR family members, including
17 beta-hydroxysteroid dehydrogenase contain an
additional helix-turn-helix motif that is not generally
found among SDRs.

C-terminal classical SDR domain. One member is
identified as a rhamnulose-1-phosphate aldolase/alcohol

glycine-rich NAD(P) binding motif and a match to the

cofactor binding motif. Complex (multidomain) SDRs such
as ketoreductase domains of fatty acid synthase have a
GGXGXXG NAD(P)-binding motif and an altered active site
motif (YXXXN). Fungal type ketoacyl reductases have a
TGXXXGX(1-2)G NAD(P)-binding motif. Some atypical SDRs
have lost catalytic activity and/or have an unusual
NAD(P)-binding motif and missing or unusual active site
residues. Reactions catalyzed within the SDR family
include isomerization, decarboxylation, epimerization,
C=N bond reduction, dehydratase activity,
dehalogenation, Enoyl-CoA reduction, and
carbonyl-alcohol oxidoreduction.

>gnl|CDD|187587 cd05326, secoisolariciresinol-DH_like_SDR_c, secoisolariciresinol
dehydrogenase (secoisolariciresinol-DH)-like, classical
(c) SDRs. Podophyllum secoisolariciresinol-DH is a homo
tetrameric, classical SDR that catalyzes the
NAD-dependent conversion of (-)-secoisolariciresinol to
(-)-matairesinol via a (-)-lactol intermediate.
(-)-Matairesinol is an intermediate to various
8'-lignans, including the cancer-preventive mammalian
lignan, and those involved in vascular plant defense.
This subgroup also includes rice momilactone A synthase
which catalyzes the conversion of
3beta-hydroxy-9betaH-pimara-7,15-dien-19,6beta-olide
into momilactone A, Arabidopsis ABA2 which during
abscisic acid (ABA) biosynthesis, catalyzes the
conversion of xanthoxin to abscisic aldehyde and, maize
Tasselseed2 which participate in the maize sex
determination pathway. SDRs are a functionally diverse
family of oxidoreductases that have a single domain with
a structurally conserved Rossmann fold (alpha/beta
folding pattern with a central beta-sheet), an
NAD(P)(H)-binding region, and a structurally diverse
C-terminal region. Classical SDRs are typically about
250 residues long, while extended SDRs are approximately
350 residues. Sequence identity between different SDR
enzymes are typically in the 15-30% range, but the
enzymes share the Rossmann fold NAD-binding motif and
characteristic NAD-binding and catalytic sequence
patterns. These enzymes catalyze a wide range of
activities including the metabolism of steroids,
cofactors, carbohydrates, lipids, aromatic compounds,
and amino acids, and act in redox sensing. Classical
SDRs have an TGXXX[AG]XG cofactor binding motif and a
YXXXK active site motif, with the Tyr residue of the
active site motif serving as a critical catalytic
residue (Tyr-151, 15-hydroxyprostaglandin dehydrogenase
(15-PGDH) numbering). In addition to the Tyr and Lys,
there is often an upstream Ser (Ser-138, 15-PGDH
numbering) and/or an Asn (Asn-107, 15-PGDH numbering)
contributing to the active site; while substrate binding
is in the C-terminal region, which determines
specificity. The standard reaction mechanism is a
4-pro-S hydride transfer and proton relay involving the
conserved Tyr and Lys, a water molecule stabilized by
Asn, and nicotinamide. Extended SDRs have additional
elements in the C-terminal region, and typically have a
TGXXGXXG cofactor binding motif. Complex (multidomain)
SDRs such as ketoreductase domains of fatty acid
synthase have a GGXGXXG NAD(P)-binding motif and an
altered active site motif (YXXXN). Fungal type ketoacyl
reductases have a TGXXXGX(1-2)G NAD(P)-binding motif.
Some atypical SDRs have lost catalytic activity and/or
have an unusual NAD(P)-binding motif and missing or
unusual active site residues. Reactions catalyzed within
the SDR family include isomerization, decarboxylation,
epimerization, C=N bond reduction, dehydratase activity,
dehalogenation, Enoyl-CoA reduction, and
carbonyl-alcohol oxidoreduction.

A_reductase (ChcA)_like, classical (c) SDRs. This
subgroup contains classical SDR proteins, including
members identified as 1-cyclohexenylcarbonyl coenzyme A
reductase. ChcA of Streptomyces collinus is implicated
in the final reduction step of shikimic acid to
ansatrienin. ChcA shows sequence similarity to the SDR
family of NAD-binding proteins, but it lacks the
conserved Tyr of the characteristic catalytic site. This
subgroup also contains the NADH-dependent
enoyl-[acyl-carrier-protein(ACP)] reductase FabL from
Bacillus subtilis. This enzyme participates in bacterial
fatty acid synthesis, in type II fatty-acid synthases
and catalyzes the last step in each elongation cycle.
SDRs are a functionally diverse family of
oxidoreductases that have a single domain with a
structurally conserved Rossmann fold (alpha/beta folding
pattern with a central beta-sheet), an NAD(P)(H)-binding
region, and a structurally diverse C-terminal region.
Classical SDRs are typically about 250 residues long,
while extended SDRS are approximately 350 residues.
Sequence identity between different SDR enzymes are
typically in the 15-30% range, but the enzymes share the
Rossmann fold NAD-binding motif and characteristic
NAD-binding and catalytic sequence patterns. These
enzymes have a 3-glycine N-terminal NAD(P)(H)-binding
pattern (typically, TGxxxGxG in classical SDRs and
TGxxGxxG in extended SDRs), while substrate binding is
in the C-terminal region. A critical catalytic Tyr
residue (Tyr-151, human 15-hydroxyprostaglandin
dehydrogenase (15-PGDH) numbering), is often found in a
conserved YXXXK pattern. In addition to the Tyr and Lys,
there is often an upstream Ser (Ser-138, 15-PGDH
numbering) and/or an Asn (Asn-107, 15-PGDH numbering) or
additional Ser, contributing to the active site.
Substrates for these enzymes include sugars, steroids,
alcohols, and aromatic compounds. The standard reaction
mechanism is a proton relay involving the conserved Tyr
and Lys, as well as Asn (or Ser). Some SDR family
members, including 17 beta-hydroxysteroid dehydrogenase
contain an additional helix-turn-helix motif that is not
generally found among SDRs.

>gnl|CDD|187610 cd05352, MDH-like_SDR_c, mannitol dehydrogenase (MDH)-like,
classical (c) SDRs. NADP-mannitol dehydrogenase
catalyzes the conversion of fructose to mannitol, an
acyclic 6-carbon sugar. MDH is a tetrameric member of
the SDR family. This subgroup also includes various
other tetrameric SDRs, including Pichia stipitis
D-arabinitol dehydrogenase (aka polyol dehydrogenase),
Candida albicans Sou1p, a sorbose reductase, and Candida
parapsilosis (S)-specific carbonyl reductase (SCR, aka
S-specific alcohol dehydrogenase) which catalyzes the
enantioselective reduction of 2-hydroxyacetophenone into
(S)-1-phenyl-1,2-ethanediol. SDRs are a functionally
diverse family of oxidoreductases that have a single
domain with a structurally conserved Rossmann fold
(alpha/beta folding pattern with a central beta-sheet),
an NAD(P)(H)-binding region, and a structurally diverse
C-terminal region. Classical SDRs are typically about
250 residues long, while extended SDRS are approximately
350 residues. Sequence identity between different SDR
enzymes are typically in the 15-30% range, but the
enzymes share the Rossmann fold NAD-binding motif and
characteristic NAD-binding and catalytic sequence
patterns. These enzymes have a 3-glycine N-terminal
NAD(P)(H)-binding pattern (typically, TGxxxGxG in
classical SDRs and TGxxGxxG in extended SDRs), while
substrate binding is in the C-terminal region. A
critical catalytic Tyr residue (Tyr-151, human
15-hydroxyprostaglandin dehydrogenase (15-PGDH)
numbering), is often found in a conserved YXXXK pattern.
In addition to the Tyr and Lys, there is often an
upstream Ser (Ser-138, 15-PGDH numbering) and/or an Asn
(Asn-107, 15-PGDH numbering) or additional Ser,
contributing to the active site. Substrates for these
enzymes include sugars, steroids, alcohols, and aromatic
compounds. The standard reaction mechanism is a proton
relay involving the conserved Tyr and Lys, as well as
Asn (or Ser).

>gnl|CDD|188169 TIGR01829, AcAcCoA_reduct, acetoacetyl-CoA reductase. This model
represent acetoacetyl-CoA reductase, a member of the
family short-chain-alcohol dehydrogenases. Note that,
despite the precision implied by the enzyme name, the
reaction of EC 1.1.1.36 is defined more generally as
(R)-3-hydroxyacyl-CoA + NADP+ = 3-oxoacyl-CoA + NADPH.
Members of this family may act in the biosynthesis of
poly-beta-hydroxybutyrate (e.g. Rhizobium meliloti) and
related poly-beta-hydroxyalkanoates. Note that the
member of this family from Azospirillum brasilense,
designated NodG, appears to lack acetoacetyl-CoA
reductase activity and to act instead in the production
of nodulation factor. This family is downgraded to
subfamily for this NodG. Other proteins designated NodG,
as from Rhizobium, belong to related but distinct
protein families.

>gnl|CDD|187604 cd05346, SDR_c5, classical (c) SDR, subgroup 5. These proteins are
members of the classical SDR family, with a canonical
active site tetrad and a typical Gly-rich NAD-binding
motif. SDRs are a functionally diverse family of
oxidoreductases that have a single domain with a
structurally conserved Rossmann fold (alpha/beta folding
pattern with a central beta-sheet), an NAD(P)(H)-binding
region, and a structurally diverse C-terminal region.
Classical SDRs are typically about 250 residues long,
while extended SDRs are approximately 350 residues.
Sequence identity between different SDR enzymes are
typically in the 15-30% range, but the enzymes share the
Rossmann fold NAD-binding motif and characteristic
NAD-binding and catalytic sequence patterns. These
enzymes catalyze a wide range of activities including
the metabolism of steroids, cofactors, carbohydrates,
lipids, aromatic compounds, and amino acids, and act in
redox sensing. Classical SDRs have an TGXXX[AG]XG
cofactor binding motif and a YXXXK active site motif,
with the Tyr residue of the active site motif serving as
a critical catalytic residue (Tyr-151, human
15-hydroxyprostaglandin dehydrogenase (15-PGDH)
numbering). In addition to the Tyr and Lys, there is
often an upstream Ser (Ser-138, 15-PGDH numbering)
and/or an Asn (Asn-107, 15-PGDH numbering) contributing
to the active site; while substrate binding is in the
C-terminal region, which determines specificity. The
standard reaction mechanism is a 4-pro-S hydride
transfer and proton relay involving the conserved Tyr
and Lys, a water molecule stabilized by Asn, and
nicotinamide. Extended SDRs have additional elements in
the C-terminal region, and typically have a TGXXGXXG
cofactor binding motif. Complex (multidomain) SDRs such
as ketoreductase domains of fatty acid synthase have a
GGXGXXG NAD(P)-binding motif and an altered active site
motif (YXXXN). Fungal type ketoacyl reductases have a
TGXXXGX(1-2)G NAD(P)-binding motif. Some atypical SDRs
have lost catalytic activity and/or have an unusual
NAD(P)-binding motif and missing or unusual active site
residues. Reactions catalyzed within the SDR family
include isomerization, decarboxylation, epimerization,
C=N bond reduction, dehydratase activity,
dehalogenation, Enoyl-CoA reduction, and
carbonyl-alcohol oxidoreduction.

These classical SDRs includes members identified as

(7 alpha-HSDH), classical (c) SDRs. This bacterial
subgroup contains 7 alpha-HSDHs, including Escherichia
coli 7 alpha-HSDH. 7 alpha-HSDH, a member of the SDR
family, catalyzes the NAD+ -dependent dehydrogenation of
a hydroxyl group at position 7 of the steroid skeleton
of bile acids. In humans the two primary bile acids are
cholic and chenodeoxycholic acids, these are formed from
cholesterol in the liver. Escherichia coli 7 alpha-HSDH
dehydroxylates these bile acids in the human intestine.
Mammalian 7 alpha-HSDH activity has been found in
livers. SDRs are a functionally diverse family of
oxidoreductases that have a single domain with a
structurally conserved Rossmann fold (alpha/beta folding
pattern with a central beta-sheet), an NAD(P)(H)-binding
region, and a structurally diverse C-terminal region.
Classical SDRs are typically about 250 residues long,
while extended SDRS are approximately 350 residues.
Sequence identity between different SDR enzymes are
typically in the 15-30% range, but the enzymes share the
Rossmann fold NAD-binding motif and characteristic
NAD-binding and catalytic sequence patterns. These
enzymes have a 3-glycine N-terminal NAD(P)(H)-binding
pattern (typically, TGxxxGxG in classical SDRs and
TGxxGxxG in extended SDRs), while substrate binding is
in the C-terminal region. A critical catalytic Tyr
residue (Tyr-151, human 15-hydroxyprostaglandin
dehydrogenase (15-PGDH) numbering), is often found in a
conserved YXXXK pattern. In addition to the Tyr and Lys,
there is often an upstream Ser (Ser-138, 15-PGDH
numbering) and/or an Asn (Asn-107, 15-PGDH numbering) or
additional Ser, contributing to the active site.
Substrates for these enzymes include sugars, steroids,
alcohols, and aromatic compounds. The standard reaction
mechanism is a proton relay involving the conserved Tyr
and Lys, as well as Asn (or Ser). Some SDR family
members, including 17 beta-hydroxysteroid dehydrogenase
contain an additional helix-turn-helix motif that is not
generally found among SDRs.

>gnl|CDD|131468 TIGR02415, 23BDH, acetoin reductases. One member of this family,
as characterized in Klebsiella terrigena, is described
as able to interconvert acetoin + NADH with
meso-2,3-butanediol + NAD(+). It is also called capable
of irreversible reduction of diacetyl with NADH to
acetoin. Blomqvist, et al. decline to specify either EC
1.1.1.4 which is (R,R)-butanediol dehydrogenase, or EC
1.1.1.5, which is acetoin dehydrogenase without a
specified stereochemistry, for this enzyme. This enzyme
is a homotetramer in the family of short chain
dehydrogenases (pfam00106). Another member of this
family, from Corynebacterium glutamicum, is called
L-2,3-butanediol dehydrogenase (PMID:11577733) [Energy
metabolism, Fermentation].

>gnl|CDD|187597 cd05338, DHRS1_HSDL2-like_SDR_c, human dehydrogenase/reductase (SDR
family) member 1 (DHRS1) and human hydroxysteroid
dehydrogenase-like protein 2 (HSDL2), classical (c)
SDRs. This subgroup includes human DHRS1 and human
HSDL2 and related proteins. These are members of the
classical SDR family, with a canonical Gly-rich
NAD-binding motif and the typical YXXXK active site
motif. However, the rest of the catalytic tetrad is not
strongly conserved. DHRS1 mRNA has been detected in many
tissues, liver, heart, skeletal muscle, kidney and
pancreas; a longer transcript is predominantly expressed
in the liver , a shorter one in the heart. HSDL2 may
play a part in fatty acid metabolism, as it is found in
peroxisomes. SDRs are a functionally diverse family of
oxidoreductases that have a single domain with a
structurally conserved Rossmann fold (alpha/beta folding
pattern with a central beta-sheet), an NAD(P)(H)-binding
region, and a structurally diverse C-terminal region.
Classical SDRs are typically about 250 residues long,
while extended SDRS are approximately 350 residues.
Sequence identity between different SDR enzymes are
typically in the 15-30% range, but the enzymes share the
Rossmann fold NAD-binding motif and characteristic
NAD-binding and catalytic sequence patterns. These
enzymes have a 3-glycine N-terminal NAD(P)(H)-binding
pattern (typically, TGxxxGxG in classical SDRs and
TGxxGxxG in extended SDRs), while substrate binding is
in the C-terminal region. A critical catalytic Tyr
residue (Tyr-151, human 15-hydroxyprostaglandin
dehydrogenase (15-PGDH) numbering), is often found in a
conserved YXXXK pattern. In addition to the Tyr and Lys,
there is often an upstream Ser (Ser-138, 15-PGDH
numbering) and/or an Asn (Asn-107, 15-PGDH numbering) or
additional Ser, contributing to the active site.
Substrates for these enzymes include sugars, steroids,
alcohols, and aromatic compounds. The standard reaction
mechanism is a proton relay involving the conserved Tyr
and Lys, as well as Asn (or Ser). Some SDR family
members, including 17 beta-hydroxysteroid dehydrogenase
contain an additional helix-turn-helix motif that is not
generally found among SDRs.

a fairly well conserved active site tetrad and domain
size of the classical SDRs, but has an atypical
NAD-binding motif ([ST]G[GA]XGXXG). SDRs are a
functionally diverse family of oxidoreductases that have
a single domain with a structurally conserved Rossmann
fold (alpha/beta folding pattern with a central
beta-sheet), an NAD(P)(H)-binding region, and a
structurally diverse C-terminal region. Classical SDRs
are typically about 250 residues long, while extended
SDRs are approximately 350 residues. Sequence identity
between different SDR enzymes are typically in the
15-30% range, but the enzymes share the Rossmann fold
NAD-binding motif and characteristic NAD-binding and
catalytic sequence patterns. These enzymes catalyze a
wide range of activities including the metabolism of
steroids, cofactors, carbohydrates, lipids, aromatic
compounds, and amino acids, and act in redox sensing.
Classical SDRs have an TGXXX[AG]XG cofactor binding
motif and a YXXXK active site motif, with the Tyr
residue of the active site motif serving as a critical
catalytic residue (Tyr-151, human
15-hydroxyprostaglandin dehydrogenase (15-PGDH)
numbering). In addition to the Tyr and Lys, there is
often an upstream Ser (Ser-138, 15-PGDH numbering)
and/or an Asn (Asn-107, 15-PGDH numbering) contributing
to the active site; while substrate binding is in the
C-terminal region, which determines specificity. The
standard reaction mechanism is a 4-pro-S hydride
transfer and proton relay involving the conserved Tyr
and Lys, a water molecule stabilized by Asn, and
nicotinamide. Extended SDRs have additional elements in
the C-terminal region, and typically have a TGXXGXXG
cofactor binding motif. Complex (multidomain) SDRs such
as ketoreductase domains of fatty acid synthase have a
GGXGXXG NAD(P)-binding motif and an altered active site
motif (YXXXN). Fungal type ketoacyl reductases have a
TGXXXGX(1-2)G NAD(P)-binding motif. Some atypical SDRs
have lost catalytic activity and/or have an unusual
NAD(P)-binding motif and missing or unusual active site
residues. Reactions catalyzed within the SDR family
include isomerization, decarboxylation, epimerization,
C=N bond reduction, dehydratase activity,
dehalogenation, Enoyl-CoA reduction, and
carbonyl-alcohol oxidoreduction.

>gnl|CDD|187591 cd05330, cyclohexanol_reductase_SDR_c, cyclohexanol reductases,
including levodione reductase, classical (c) SDRs.
Cyloclohexanol reductases,including
(6R)-2,2,6-trimethyl-1,4-cyclohexanedione (levodione)
reductase of Corynebacterium aquaticum, catalyze the
reversible oxidoreduction of hydroxycyclohexanone
derivatives. SDRs are a functionally diverse family of
oxidoreductases that have a single domain with a
structurally conserved Rossmann fold (alpha/beta folding
pattern with a central beta-sheet), an NAD(P)(H)-binding
region, and a structurally diverse C-terminal region.
Classical SDRs are typically about 250 residues long,
while extended SDRs are approximately 350 residues.
Sequence identity between different SDR enzymes are
typically in the 15-30% range, but the enzymes share the
Rossmann fold NAD-binding motif and characteristic
NAD-binding and catalytic sequence patterns. These
enzymes catalyze a wide range of activities including
the metabolism of steroids, cofactors, carbohydrates,
lipids, aromatic compounds, and amino acids, and act in
redox sensing. Classical SDRs have an TGXXX[AG]XG
cofactor binding motif and a YXXXK active site motif,
with the Tyr residue of the active site motif serving as
a critical catalytic residue (Tyr-151, human
15-hydroxyprostaglandin dehydrogenase (15-PGDH)
numbering). In addition to the Tyr and Lys, there is
often an upstream Ser (Ser-138, 15-PGDH numbering)
and/or an Asn (Asn-107, 15-PGDH numbering) contributing
to the active site; while substrate binding is in the
C-terminal region, which determines specificity. The
standard reaction mechanism is a 4-pro-S hydride
transfer and proton relay involving the conserved Tyr
and Lys, a water molecule stabilized by Asn, and
nicotinamide. Extended SDRs have additional elements in
the C-terminal region, and typically have a TGXXGXXG
cofactor binding motif. Complex (multidomain) SDRs such
as ketoreductase domains of fatty acid synthase have a
GGXGXXG NAD(P)-binding motif and an altered active site
motif (YXXXN). Fungal type ketoacyl reductases have a
TGXXXGX(1-2)G NAD(P)-binding motif. Some atypical SDRs
have lost catalytic activity and/or have an unusual
NAD(P)-binding motif and missing or unusual active site
residues. Reactions catalyzed within the SDR family
include isomerization, decarboxylation, epimerization,
C=N bond reduction, dehydratase activity,
dehalogenation, Enoyl-CoA reduction, and
carbonyl-alcohol oxidoreduction.

>gnl|CDD|187615 cd05357, PR_SDR_c, pteridine reductase (PR), classical (c) SDRs.
Pteridine reductases (PRs), members of the SDR family,
catalyzes the NAD-dependent reduction of folic acid,
dihydrofolate and related compounds. In Leishmania,
pteridine reductase (PTR1) acts to circumvent the
anti-protozoan drugs that attack dihydrofolate reductase
activity. Proteins in this subgroup have an N-terminal
NAD-binding motif and a YxxxK active site motif, but
have an Asp instead of the usual upstream catalytic Ser.
SDRs are a functionally diverse family of
oxidoreductases that have a single domain with a
structurally conserved Rossmann fold (alpha/beta folding
pattern with a central beta-sheet), an NAD(P)(H)-binding
region, and a structurally diverse C-terminal region.
Classical SDRs are typically about 250 residues long,
while extended SDRS are approximately 350 residues.
Sequence identity between different SDR enzymes are
typically in the 15-30% range, but the enzymes share the
Rossmann fold NAD-binding motif and characteristic
NAD-binding and catalytic sequence patterns. These
enzymes have a 3-glycine N-terminal NAD(P)(H)-binding
pattern (typically, TGxxxGxG in classical SDRs and
TGxxGxxG in extended SDRs), while substrate binding is
in the C-terminal region. A critical catalytic Tyr
residue (Tyr-151, human 15-hydroxyprostaglandin
dehydrogenase (15-PGDH) numbering), is often found in a
conserved YXXXK pattern. In addition to the Tyr and Lys,
there is often an upstream Ser (Ser-138, 15-PGDH
numbering) and/or an Asn (Asn-107, 15-PGDH numbering) or
additional Ser, contributing to the active site.
Substrates for these enzymes include sugars, steroids,
alcohols, and aromatic compounds. The standard reaction
mechanism is a proton relay involving the conserved Tyr
and Lys, as well as Asn (or Ser). Some SDR family
members, including 17 beta-hydroxysteroid dehydrogenase
contain an additional helix-turn-helix motif that is not
generally found among SDRs.

1,6-dihydroxycyclohexa-2,4-diene-1-carboxylate
dehydrogenase (DHB DH)-like, classical (c) SDR. DHB DH
(aka 1,2-dihydroxycyclohexa-3,5-diene-1-carboxylate
dehydrogenase) catalyzes the NAD-dependent conversion of
1,2-dihydroxycyclohexa-3,4-diene carboxylate to a
catechol. This subgroup also contains Pseudomonas putida
F1 CmtB, 2,3-dihydroxy-2,3-dihydro-p-cumate
dehydrogenase, the second enzyme in the pathway for
catabolism of p-cumate catabolism. This subgroup shares
the glycine-rich NAD-binding motif of the classical SDRs
and shares the same catalytic triad; however, the
upstream Asn implicated in cofactor binding or catalysis
in other SDRs is generally substituted by a Ser. SDRs
are a functionally diverse family of oxidoreductases
that have a single domain with a structurally conserved
Rossmann fold (alpha/beta folding pattern with a central
beta-sheet), an NAD(P)(H)-binding region, and a
structurally diverse C-terminal region. Classical SDRs
are typically about 250 residues long, while extended
SDRs are approximately 350 residues. Sequence identity
between different SDR enzymes are typically in the
15-30% range, but the enzymes share the Rossmann fold
NAD-binding motif and characteristic NAD-binding and
catalytic sequence patterns. These enzymes catalyze a
wide range of activities including the metabolism of
steroids, cofactors, carbohydrates, lipids, aromatic
compounds, and amino acids, and act in redox sensing.
Classical SDRs have an TGXXX[AG]XG cofactor binding
motif and a YXXXK active site motif, with the Tyr
residue of the active site motif serving as a critical
catalytic residue (Tyr-151, human
15-hydroxyprostaglandin dehydrogenase (15-PGDH)
numbering). In addition to the Tyr and Lys, there is
often an upstream Ser (Ser-138, 15-PGDH numbering)
and/or an Asn (Asn-107, 15-PGDH numbering) contributing
to the active site; while substrate binding is in the
C-terminal region, which determines specificity. The
standard reaction mechanism is a 4-pro-S hydride
transfer and proton relay involving the conserved Tyr
and Lys, a water molecule stabilized by Asn, and
nicotinamide. Extended SDRs have additional elements in
the C-terminal region, and typically have a TGXXGXXG
cofactor binding motif. Complex (multidomain) SDRs such
as ketoreductase domains of fatty acid synthase have a
GGXGXXG NAD(P)-binding motif and an altered active site
motif (YXXXN). Fungal type ketoacyl reductases have a
TGXXXGX(1-2)G NAD(P)-binding motif. Some atypical SDRs
have lost catalytic activity and/or have an unusual

residues. Reactions catalyzed within the SDR family

(HSD10)-like, classical (c) SDRs. HSD10, also known as
amyloid-peptide-binding alcohol dehydrogenase (ABAD),
was previously identified as a L-3-hydroxyacyl-CoA
dehydrogenase, HADH2. In fatty acid metabolism, HADH2
catalyzes the third step of beta-oxidation, the
conversion of a hydroxyl to a keto group in the
NAD-dependent oxidation of L-3-hydroxyacyl CoA. In
addition to alcohol dehydrogenase and HADH2 activites,
HSD10 has steroid dehydrogenase activity. Although the
mechanism is unclear, HSD10 is implicated in the
formation of amyloid beta-petide in the brain (which is
linked to the development of Alzheimer's disease).
Although HSD10 is normally concentrated in the
mitochondria, in the presence of amyloid beta-peptide it
translocates into the plasma membrane, where it's action
may generate cytotoxic aldehydes and may lower estrogen
levels through its use of 17-beta-estradiol as a
substrate. HSD10 is a member of the SRD family, but
differs from other SDRs by the presence of two
insertions of unknown function. SDRs are a functionally
diverse family of oxidoreductases that have a single

>gnl|CDD|187640 cd08935, mannonate_red_SDR_c, putative D-mannonate oxidoreductase,
classical (c) SDR. D-mannonate oxidoreductase catalyzes
the NAD-dependent interconversion of D-mannonate and
D-fructuronate. This subgroup includes Bacillus
subtitils UxuB/YjmF, a putative D-mannonate
oxidoreductase; the B. subtilis UxuB gene is part of a
putative ten-gene operon (the Yjm operon) involved in
hexuronate catabolism. Escherichia coli UxuB does not
belong to this subgroup. This subgroup has a canonical
active site tetrad and a typical Gly-rich NAD-binding
motif. SDRs are a functionally diverse family of
oxidoreductases that have a single domain with a
structurally conserved Rossmann fold (alpha/beta folding
pattern with a central beta-sheet), an NAD(P)(H)-binding
region, and a structurally diverse C-terminal region.
Classical SDRs are typically about 250 residues long,
while extended SDRs are approximately 350 residues.
Sequence identity between different SDR enzymes are
typically in the 15-30% range, but the enzymes share the
Rossmann fold NAD-binding motif and characteristic
NAD-binding and catalytic sequence patterns. These
enzymes catalyze a wide range of activities including
the metabolism of steroids, cofactors, carbohydrates,
lipids, aromatic compounds, and amino acids, and act in
redox sensing. Classical SDRs have an TGXXX[AG]XG
cofactor binding motif and a YXXXK active site motif,
with the Tyr residue of the active site motif serving as
a critical catalytic residue (Tyr-151, human
15-hydroxyprostaglandin dehydrogenase (15-PGDH)
numbering). In addition to the Tyr and Lys, there is
often an upstream Ser (Ser-138, 15-PGDH numbering)
and/or an Asn (Asn-107, 15-PGDH numbering) contributing
to the active site; while substrate binding is in the
C-terminal region, which determines specificity. The
standard reaction mechanism is a 4-pro-S hydride
transfer and proton relay involving the conserved Tyr
and Lys, a water molecule stabilized by Asn, and
nicotinamide. Extended SDRs have additional elements in
the C-terminal region, and typically have a TGXXGXXG
cofactor binding motif. Complex (multidomain) SDRs such
as ketoreductase domains of fatty acid synthase have a
GGXGXXG NAD(P)-binding motif and an altered active site
motif (YXXXN). Fungal type ketoacyl reductases have a
TGXXXGX(1-2)G NAD(P)-binding motif. Some atypical SDRs
have lost catalytic activity and/or have an unusual
NAD(P)-binding motif and missing or unusual active site
residues. Reactions catalyzed within the SDR family
include isomerization, decarboxylation, epimerization,
C=N bond reduction, dehydratase activity,
dehalogenation, Enoyl-CoA reduction, and
carbonyl-alcohol oxidoreduction.

>gnl|CDD|187596 cd05337, BKR_1_SDR_c, putative beta-ketoacyl acyl carrier protein
[ACP] reductase (BKR), subgroup 1, classical (c) SDR.
This subgroup includes Escherichia coli CFT073 FabG. The
Escherichai coli K12 BKR, FabG, belongs to a different
subgroup. BKR catalyzes the NADPH-dependent reduction of
ACP in the first reductive step of de novo fatty acid
synthesis (FAS). FAS consists of four elongation steps,
which are repeated to extend the fatty acid chain
through the addition of two-carbo units from malonyl
acyl-carrier protein (ACP): condensation, reduction,
dehydration, and a final reduction. Type II FAS, typical
of plants and many bacteria, maintains these activities
on discrete polypeptides, while type I FAS utilizes one
or two multifunctional polypeptides. BKR resembles enoyl
reductase, which catalyzes the second reduction step in
FAS. SDRs are a functionally diverse family of
oxidoreductases that have a single domain with
structurally conserved Rossmann fold (alpha/beta folding
pattern with a central beta-sheet) NAD(P)(H) binding
region and a structurally diverse C-terminal region.
Classical SDRs are typically about 250 residues long,
while extended SDRS are approximately 350 residues.
Sequence identity between different SDR enzymes are
typically in the 15-30% range, but the enzymes share the
Rossmann fold NAD binding motif and characteristic
NAD-binding and catalytic sequence patterns. These
enzymes have a 3-glycine N-terminal NAD(P)(H) binding
pattern: TGxxxGxG in classical SDRs. Extended SDRs have
additional elements in the C-terminal region, and
typically have a TGXXGXXG cofactor binding motif.
Complex (multidomain) SDRs such as ketoreductase domains
of fatty acid synthase have a GGXGXXG NAD(P) binding
motif and an altered active site motif (YXXXN). Fungal
type type ketoacyl reductases have a TGXXXGX(1-2)G
NAD(P)-binding motif. Some atypical SDRs have lost
catalytic activity and/or have an unusual NAD(P) binding
motif and missing or unusual active site residues.
Reactions catalyzed within the SDR family include
isomerization, decarboxylation, epimerization, C=N bond
reduction, dehydratase activity, dehalogenation,
Enoyl-CoA reduction, and carbonyl-alcohol
oxidoreduction. A critical catalytic Tyr residue
(Tyr-151, human 15-hydroxyprostaglandin dehydrogenase
(15-PGDH) numbering), is often found in a conserved
YXXXK pattern. In addition to the Tyr and Lys, there is
often an upstream Ser (Ser-138, 15-PGDH numbering)
and/or an Asn (Asn-107, 15-PGDH numbering) or additional
Ser, contributing to the active site. Substrates for
these enzymes include sugars, steroids, alcohols, and
aromatic compounds. The standard reaction mechanism is a
proton relay involving the conserved Tyr-151 and
Lys-155, and well as Asn-111 (or Ser). Some SDR family
members, including 17 beta-hydroxysteroid dehydrogenase
contain an additional helix-turn-helix motif that is not
generally found among SDRs.

dehydrogenases (17beta-HSDs) types -1, -3, and -12,
-like, classical (c) SDRs. This subgroup includes
various 17-beta-hydroxysteroid dehydrogenases and
3-ketoacyl-CoA reductase, these are members of the SDR
family, and contain the canonical active site tetrad and
glycine-rich NAD-binding motif of the classical SDRs.
3-ketoacyl-CoA reductase (KAR, aka 17beta-HSD type 12,
encoded by HSD17B12) acts in fatty acid elongation;
17beta- hydroxysteroid dehydrogenases are isozymes that
catalyze activation and inactivation of estrogen and
androgens, and include members of the SDR family.
17beta-estradiol dehydrogenase (aka 17beta-HSD type 1,
encoded by HSD17B1) converts estrone to estradiol.
Estradiol is the predominant female sex hormone.
17beta-HSD type 3 (aka testosterone
17-beta-dehydrogenase 3, encoded by HSD17B3) catalyses
the reduction of androstenedione to testosterone, it
also accepts estrogens as substrates. This subgroup also
contains a putative steroid dehydrogenase let-767 from
Caenorhabditis elegans, mutation in which results in
hypersensitivity to cholesterol limitation. SDRs are a
functionally diverse family of oxidoreductases that have
a single domain with a structurally conserved Rossmann
fold (alpha/beta folding pattern with a central
beta-sheet), an NAD(P)(H)-binding region, and a
structurally diverse C-terminal region. Classical SDRs
are typically about 250 residues long, while extended
SDRS are approximately 350 residues. Sequence identity
between different SDR enzymes are typically in the
15-30% range, but the enzymes share the Rossmann fold
NAD-binding motif and characteristic NAD-binding and
catalytic sequence patterns. These enzymes have a
3-glycine N-terminal NAD(P)(H)-binding pattern
(typically, TGxxxGxG in classical SDRs and TGxxGxxG in
extended SDRs), while substrate binding is in the
C-terminal region. A critical catalytic Tyr residue
(Tyr-151, human 15-hydroxyprostaglandin dehydrogenase
(15-PGDH) numbering), is often found in a conserved
YXXXK pattern. In addition to the Tyr and Lys, there is
often an upstream Ser (Ser-138, 15-PGDH numbering)
and/or an Asn (Asn-107, 15-PGDH numbering) or additional
Ser, contributing to the active site. Substrates for
these enzymes include sugars, steroids, alcohols, and
aromatic compounds. The standard reaction mechanism is a
proton relay involving the conserved Tyr and Lys, as
well as Asn (or Ser). Some SDR family members, including
17 beta-hydroxysteroid dehydrogenase contain an
additional helix-turn-helix motif that is not generally
found among SDRs.

This subgroup includes human DHRS1 and related proteins.
These are members of the classical SDR family, with a
canonical Gly-rich NAD-binding motif and the typical
YXXXK active site motif. However, the rest of the
catalytic tetrad is not strongly conserved. DHRS1 mRNA
has been detected in many tissues, liver, heart,
skeletal muscle, kidney and pancreas; a longer
transcript is predominantly expressed in the liver , a
shorter one in the heart. SDRs are a functionally
diverse family of oxidoreductases that have a single
domain with a structurally conserved Rossmann fold
(alpha/beta folding pattern with a central beta-sheet),
an NAD(P)(H)-binding region, and a structurally diverse

>gnl|CDD|187607 cd05349, BKR_2_SDR_c, putative beta-ketoacyl acyl carrier protein
[ACP]reductase (BKR), subgroup 2, classical (c) SDR.
This subgroup includes Rhizobium sp. NGR234 FabG1. The
Escherichai coli K12 BKR, FabG, belongs to a different
subgroup. BKR catalyzes the NADPH-dependent reduction of
ACP in the first reductive step of de novo fatty acid
synthesis (FAS). FAS consists of four elongation steps,
which are repeated to extend the fatty acid chain
through the addition of two-carbo units from malonyl
acyl-carrier protein (ACP): condensation, reduction,
dehydration, and a final reduction. Type II FAS, typical
of plants and many bacteria, maintains these activities
on discrete polypeptides, while type I FAS utilizes one
or two multifunctional polypeptides. BKR resembles enoyl
reductase, which catalyzes the second reduction step in
FAS. SDRs are a functionally diverse family of
oxidoreductases that have a single domain with a
structurally conserved Rossmann fold (alpha/beta folding
pattern with a central beta-sheet), an NAD(P)(H)-binding
region, and a structurally diverse C-terminal region.
Classical SDRs are typically about 250 residues long,
while extended SDRS are approximately 350 residues.
Sequence identity between different SDR enzymes are
typically in the 15-30% range, but the enzymes share the
Rossmann fold NAD-binding motif and characteristic
NAD-binding and catalytic sequence patterns. These
enzymes have a 3-glycine N-terminal NAD(P)(H)-binding
pattern (typically, TGxxxGxG in classical SDRs and

SDRs. Human Mgc4172-like proteins, putative SDRs. These
proteins are members of the SDR family, with a canonical
active site tetrad and a typical Gly-rich NAD-binding

Classical SDRs are typically about 250 residues long,
while extended SDRs are approximately 350 residues.
Sequence identity between different SDR enzymes are
typically in the 15-30% range, but the enzymes share the
Rossmann fold NAD-binding motif and characteristic
NAD-binding and catalytic sequence patterns. These
enzymes catalyze a wide range of activities including
the metabolism of steroids, cofactors, carbohydrates,
lipids, aromatic compounds, and amino acids, and act in
redox sensing. Classical SDRs have an TGXXX[AG]XG
cofactor binding motif and a YXXXK active site motif,
with the Tyr residue of the active site motif serving as
a critical catalytic residue (Tyr-151, human
15-hydroxyprostaglandin dehydrogenase (15-PGDH)
numbering). In addition to the Tyr and Lys, there is
often an upstream Ser (Ser-138, 15-PGDH numbering)
and/or an Asn (Asn-107, 15-PGDH numbering) contributing
to the active site; while substrate binding is in the
C-terminal region, which determines specificity. The
standard reaction mechanism is a 4-pro-S hydride
transfer and proton relay involving the conserved Tyr
and Lys, a water molecule stabilized by Asn, and
nicotinamide. Extended SDRs have additional elements in
the C-terminal region, and typically have a TGXXGXXG
cofactor binding motif. Complex (multidomain) SDRs such
as ketoreductase domains of fatty acid synthase have a
GGXGXXG NAD(P)-binding motif and an altered active site
motif (YXXXN). Fungal type ketoacyl reductases have a
TGXXXGX(1-2)G NAD(P)-binding motif. Some atypical SDRs
have lost catalytic activity and/or have an unusual
NAD(P)-binding motif and missing or unusual active site
residues. Reactions catalyzed within the SDR family
include isomerization, decarboxylation, epimerization,
C=N bond reduction, dehydratase activity,
dehalogenation, Enoyl-CoA reduction, and
carbonyl-alcohol oxidoreduction.

The enzymatic properties were confirmed experimentally
in Rhodopseudomonas palustris; the enzyme is
homotetrameric, and not sensitive to oxygen. This enzyme
is part of proposed pathway for degradation of
benzoyl-CoA to 3-hydroxypimeloyl-CoA that differs from
the analogous in Thauera aromatica. It also may occur in
degradation of the non-aromatic compound
cyclohexane-1-carboxylate.

>gnl|CDD|187598 cd05339, 17beta-HSDXI-like_SDR_c, human 17-beta-hydroxysteroid
dehydrogenase XI-like, classical (c) SDRs.
17-beta-hydroxysteroid dehydrogenases (17betaHSD) are a
group of isozymes that catalyze activation and
inactivation of estrogen and androgens. 17betaHSD type
XI, a classical SDR, preferentially converts
3alpha-adiol to androsterone but not numerous other
tested steroids. This subgroup of classical SDRs also
includes members identified as retinol dehydrogenases,
which convert retinol to retinal, a property that
overlaps with 17betaHSD activity. SDRs are a
functionally diverse family of oxidoreductases that have
a single domain with a structurally conserved Rossmann
fold (alpha/beta folding pattern with a central
beta-sheet), an NAD(P)(H)-binding region, and a
structurally diverse C-terminal region. Classical SDRs
are typically about 250 residues long, while extended
SDRS are approximately 350 residues. Sequence identity
between different SDR enzymes are typically in the
15-30% range, but the enzymes share the Rossmann fold
NAD-binding motif and characteristic NAD-binding and
catalytic sequence patterns. These enzymes have a
3-glycine N-terminal NAD(P)(H)-binding pattern
(typically, TGxxxGxG in classical SDRs and TGxxGxxG in
extended SDRs), while substrate binding is in the
C-terminal region. A critical catalytic Tyr residue
(Tyr-151, human 15-hydroxyprostaglandin dehydrogenase
(15-PGDH) numbering), is often found in a conserved
YXXXK pattern. In addition to the Tyr and Lys, there is
often an upstream Ser (Ser-138, 15-PGDH numbering)
and/or an Asn (Asn-107, 15-PGDH numbering) or additional
Ser, contributing to the active site. Substrates for
these enzymes include sugars, steroids, alcohols, and
aromatic compounds. The standard reaction mechanism is a
proton relay involving the conserved Tyr and Lys, as
well as Asn (or Ser). Some SDR family members, including
17 beta-hydroxysteroid dehydrogenase contain an
additional helix-turn-helix motif that is not generally
found among SDRs.

>gnl|CDD|187628 cd05370, SDR_c2, classical (c) SDR, subgroup 2. Short-chain
dehydrogenases/reductases (SDRs, aka Tyrosine-dependent
oxidoreductases) are a functionally diverse family of
oxidoreductases that have a single domain with a
structurally conserved Rossmann fold (alpha/beta folding
pattern with a central beta-sheet), an NAD(P)(H)-binding
region, and a structurally diverse C-terminal region.
Classical SDRs are typically about 250 residues long,
while extended SDRs are approximately 350 residues.
Sequence identity between different SDR enzymes are
typically in the 15-30% range, but the enzymes share the
Rossmann fold NAD-binding motif and characteristic
NAD-binding and catalytic sequence patterns. These
enzymes catalyze a wide range of activities including
the metabolism of steroids, cofactors, carbohydrates,
lipids, aromatic compounds, and amino acids, and act in
redox sensing. Classical SDRs have an TGXXX[AG]XG
cofactor binding motif and a YXXXK active site motif,
with the Tyr residue of the active site motif serving as
a critical catalytic residue (Tyr-151, human
15-hydroxyprostaglandin dehydrogenase (15-PGDH)
numbering). In addition to the Tyr and Lys, there is
often an upstream Ser (Ser-138, 15-PGDH numbering)
and/or an Asn (Asn-107, 15-PGDH numbering) contributing
to the active site; while substrate binding is in the
C-terminal region, which determines specificity. The
standard reaction mechanism is a 4-pro-S hydride
transfer and proton relay involving the conserved Tyr
and Lys, a water molecule stabilized by Asn, and
nicotinamide. Extended SDRs have additional elements in
the C-terminal region, and typically have a TGXXGXXG
cofactor binding motif. Complex (multidomain) SDRs such
as ketoreductase domains of fatty acid synthase have a
GGXGXXG NAD(P)-binding motif and an altered active site
motif (YXXXN). Fungal type ketoacyl reductases have a
TGXXXGX(1-2)G NAD(P)-binding motif. Some atypical SDRs
have lost catalytic activity and/or have an unusual
NAD(P)-binding motif and missing or unusual active site
residues. Reactions catalyzed within the SDR family
include isomerization, decarboxylation, epimerization,
C=N bond reduction, dehydratase activity,
dehalogenation, Enoyl-CoA reduction, and
carbonyl-alcohol oxidoreduction.

cis-biphenyl-2,3-dihydrodiol-2,3-dehydrogenase
(BphB)-like, classical (c) SDRs.
cis-biphenyl-2,3-dihydrodiol-2,3-dehydrogenase (BphB) is
a classical SDR, it is of particular importance for its
role in the degradation of biphenyl/polychlorinated
biphenyls(PCBs); PCBs are a significant source of
environmental contamination. This subgroup also includes
Pseudomonas putida F1
cis-biphenyl-1,2-dihydrodiol-1,2-dehydrogenase (aka
cis-benzene glycol dehydrogenase, encoded by the bnzE
gene), which participates in benzene metabolism. In
addition it includes Pseudomonas sp. C18 putative
1,2-dihydroxy-1,2-dihydronaphthalene dehydrogenase (aka
dibenzothiophene dihydrodiol dehydrogenase, encoded by
the doxE gene) which participates in an upper
naphthalene catabolic pathway. SDRs are a functionally
diverse family of oxidoreductases that have a single
domain with a structurally conserved Rossmann fold
(alpha/beta folding pattern with a central beta-sheet),
an NAD(P)(H)-binding region, and a structurally diverse
C-terminal region. Classical SDRs are typically about
250 residues long, while extended SDRs are approximately
350 residues. Sequence identity between different SDR
enzymes are typically in the 15-30% range, but the
enzymes share the Rossmann fold NAD-binding motif and
characteristic NAD-binding and catalytic sequence
patterns. These enzymes catalyze a wide range of
activities including the metabolism of steroids,
cofactors, carbohydrates, lipids, aromatic compounds,
and amino acids, and act in redox sensing. Classical
SDRs have an TGXXX[AG]XG cofactor binding motif and a
YXXXK active site motif, with the Tyr residue of the
active site motif serving as a critical catalytic
residue (Tyr-151, human 15-hydroxyprostaglandin
dehydrogenase (15-PGDH) numbering). In addition to the
Tyr and Lys, there is often an upstream Ser (Ser-138,
15-PGDH numbering) and/or an Asn (Asn-107, 15-PGDH
numbering) contributing to the active site; while
substrate binding is in the C-terminal region, which
determines specificity. The standard reaction mechanism
is a 4-pro-S hydride transfer and proton relay involving
the conserved Tyr and Lys, a water molecule stabilized
by Asn, and nicotinamide. Extended SDRs have additional
elements in the C-terminal region, and typically have a
TGXXGXXG cofactor binding motif. Complex (multidomain)
SDRs such as ketoreductase domains of fatty acid
synthase have a GGXGXXG NAD(P)-binding motif and an
altered active site motif (YXXXN). Fungal type ketoacyl
reductases have a TGXXXGX(1-2)G NAD(P)-binding motif.
Some atypical SDRs have lost catalytic activity and/or
have an unusual NAD(P)-binding motif and missing or
unusual active site residues. Reactions catalyzed within
the SDR family include isomerization, decarboxylation,
epimerization, C=N bond reduction, dehydratase activity,
dehalogenation, Enoyl-CoA reduction, and
carbonyl-alcohol oxidoreduction.

Polyketide ketoreductase (KR) is a classical SDR with a
characteristic NAD-binding pattern and active site
tetrad. Aromatic polyketides include various aromatic
compounds of pharmaceutical interest. Polyketide KR,
part of the type II polyketide synthase (PKS) complex,
is comprised of stand-alone domains that resemble the
domains found in fatty acid synthase and multidomain
type I PKS. SDRs are a functionally diverse family of
oxidoreductases that have a single domain with a
structurally conserved Rossmann fold (alpha/beta folding
pattern with a central beta-sheet), an NAD(P)(H)-binding
region, and a structurally diverse C-terminal region.
Classical SDRs are typically about 250 residues long,
while extended SDRS are approximately 350 residues.
Sequence identity between different SDR enzymes are
typically in the 15-30% range, but the enzymes share the
Rossmann fold NAD-binding motif and characteristic
NAD-binding and catalytic sequence patterns. These
enzymes have a 3-glycine N-terminal NAD(P)(H)-binding
pattern (typically, TGxxxGxG in classical SDRs and
TGxxGxxG in extended SDRs), while substrate binding is
in the C-terminal region. A critical catalytic Tyr
residue (Tyr-151, human 15-hydroxyprostaglandin
dehydrogenase (15-PGDH) numbering), is often found in a

there is often an upstream Ser (Ser-138, 15-PGDH
numbering) and/or an Asn (Asn-107, 15-PGDH numbering) or

Substrates for these enzymes include sugars, steroids,
alcohols, and aromatic compounds. The standard reaction
mechanism is a proton relay involving the conserved Tyr
and Lys, as well as Asn (or Ser). Some SDR family
members, including 17 beta-hydroxysteroid dehydrogenase
contain an additional helix-turn-helix motif that is not
generally found among SDRs.

>gnl|CDD|187630 cd05372, ENR_SDR, Enoyl acyl carrier protein (ACP) reductase (ENR),
divergent SDR. This bacterial subgroup of ENRs includes
Escherichia coli ENR. ENR catalyzes the
NAD(P)H-dependent reduction of enoyl-ACP in the last
step of fatty acid biosynthesis. De novo fatty acid
biosynthesis is catalyzed by the fatty acid synthetase
complex, through the serial addition of 2-carbon
subunits. In bacteria and plants,ENR catalyzes one of
six synthetic steps in this process. Oilseed rape ENR,
and also apparently the NADH-specific form of
Escherichia coli ENR, is tetrameric. Although similar
to the classical SDRs, this group does not have the
canonical catalytic tetrad, nor does it have the typical
Gly-rich NAD-binding pattern. Such so-called divergent
SDRs have a GXXXXXSXA NAD-binding motif and a YXXMXXXK
(or YXXXMXXXK) active site motif. SDRs are a
functionally diverse family of oxidoreductases that have
a single domain with a structurally conserved Rossmann
fold (alpha/beta folding pattern with a central
beta-sheet), an NAD(P)(H)-binding region, and a
structurally diverse C-terminal region. Classical SDRs
are typically about 250 residues long, while extended
SDRs are approximately 350 residues. Sequence identity
between different SDR enzymes are typically in the
15-30% range, but the enzymes share the Rossmann fold
NAD-binding motif and characteristic NAD-binding and
catalytic sequence patterns. These enzymes catalyze a
wide range of activities including the metabolism of
steroids, cofactors, carbohydrates, lipids, aromatic
compounds, and amino acids, and act in redox sensing.
Classical SDRs have an TGXXX[AG]XG cofactor binding
motif and a YXXXK active site motif, with the Tyr
residue of the active site motif serving as a critical
catalytic residue (Tyr-151, human
15-hydroxyprostaglandin dehydrogenase (15-PGDH)
numbering). In addition to the Tyr and Lys, there is
often an upstream Ser (Ser-138, 15-PGDH numbering)
and/or an Asn (Asn-107, 15-PGDH numbering) contributing
to the active site; while substrate binding is in the
C-terminal region, which determines specificity. The
standard reaction mechanism is a 4-pro-S hydride
transfer and proton relay involving the conserved Tyr
and Lys, a water molecule stabilized by Asn, and
nicotinamide. Extended SDRs have additional elements in
the C-terminal region, and typically have a TGXXGXXG
cofactor binding motif. Complex (multidomain) SDRs such
as ketoreductase domains of fatty acid synthase have a
GGXGXXG NAD(P)-binding motif and an altered active site
motif (YXXXN). Fungal type ketoacyl reductases have a
TGXXXGX(1-2)G NAD(P)-binding motif. Some atypical SDRs
have lost catalytic activity and/or have an unusual
NAD(P)-binding motif and missing or unusual active site
residues. Reactions catalyzed within the SDR family
include isomerization, decarboxylation, epimerization,
C=N bond reduction, dehydratase activity,
dehalogenation, Enoyl-CoA reduction, and
carbonyl-alcohol oxidoreduction.

>gnl|CDD|187585 cd05324, carb_red_PTCR-like_SDR_c, Porcine testicular carbonyl
reductase (PTCR)-like, classical (c) SDRs. PTCR is a
classical SDR which catalyzes the NADPH-dependent
reduction of ketones on steroids and prostaglandins.
Unlike most SDRs, PTCR functions as a monomer. This
subgroup also includes human carbonyl reductase 1 (CBR1)
and CBR3. CBR1 is an NADPH-dependent SDR with broad
substrate specificity and may be responsible for the in
vivo reduction of quinones, prostaglandins, and other
carbonyl-containing compounds. In addition it includes
poppy NADPH-dependent salutaridine reductase which
catalyzes the stereospecific reduction of salutaridine
to 7(S)-salutaridinol in the biosynthesis of morphine,
and Arabidopsis SDR1,a menthone reductase, which
catalyzes the reduction of menthone to neomenthol, a
compound with antimicrobial activity; SDR1 can also
carry out neomenthol oxidation. SDRs are a functionally
diverse family of oxidoreductases that have a single
domain with a structurally conserved Rossmann fold
(alpha/beta folding pattern with a central beta-sheet),
an NAD(P)(H)-binding region, and a structurally diverse
C-terminal region. Classical SDRs are typically about
250 residues long, while extended SDRs are approximately
350 residues. Sequence identity between different SDR
enzymes are typically in the 15-30% range, but the
enzymes share the Rossmann fold NAD-binding motif and
characteristic NAD-binding and catalytic sequence
patterns. These enzymes catalyze a wide range of
activities including the metabolism of steroids,
cofactors, carbohydrates, lipids, aromatic compounds,
and amino acids, and act in redox sensing. Classical
SDRs have an TGXXX[AG]XG cofactor binding motif and a
YXXXK active site motif, with the Tyr residue of the
active site motif serving as a critical catalytic
residue (Tyr-151, 15-hydroxyprostaglandin dehydrogenase
(15-PGDH) numbering). In addition to the Tyr and Lys,
there is often an upstream Ser (Ser-138, 15-PGDH
numbering) and/or an Asn (Asn-107, 15-PGDH numbering)
contributing to the active site; while substrate binding
is in the C-terminal region, which determines
specificity. The standard reaction mechanism is a
4-pro-S hydride transfer and proton relay involving the
conserved Tyr and Lys, a water molecule stabilized by
Asn, and nicotinamide. Extended SDRs have additional
elements in the C-terminal region, and typically have a
TGXXGXXG cofactor binding motif. Complex (multidomain)
SDRs such as ketoreductase domains of fatty acid
synthase have a GGXGXXG NAD(P)-binding motif and an
altered active site motif (YXXXN). Fungal type ketoacyl
reductases have a TGXXXGX(1-2)G NAD(P)-binding motif.
Some atypical SDRs have lost catalytic activity and/or
have an unusual NAD(P)-binding motif and missing or
unusual active site residues. Reactions catalyzed within
the SDR family include isomerization, decarboxylation,
epimerization, C=N bond reduction, dehydratase activity,
dehalogenation, Enoyl-CoA reduction, and
carbonyl-alcohol oxidoreduction.

>gnl|CDD|187608 cd05350, SDR_c6, classical (c) SDR, subgroup 6. These proteins are
members of the classical SDR family, with a canonical
active site tetrad and a fairly well conserved typical
Gly-rich NAD-binding motif. SDRs are a functionally
diverse family of oxidoreductases that have a single
domain with a structurally conserved Rossmann fold
(alpha/beta folding pattern with a central beta-sheet),
an NAD(P)(H)-binding region, and a structurally diverse
C-terminal region. Classical SDRs are typically about
250 residues long, while extended SDRS are approximately
350 residues. Sequence identity between different SDR
enzymes are typically in the 15-30% range, but the
enzymes share the Rossmann fold NAD-binding motif and
characteristic NAD-binding and catalytic sequence
patterns. These enzymes have a 3-glycine N-terminal
NAD(P)(H)-binding pattern (typically, TGxxxGxG in
classical SDRs and TGxxGxxG in extended SDRs), while
substrate binding is in the C-terminal region. A
critical catalytic Tyr residue (Tyr-151, human
15-hydroxyprostaglandin dehydrogenase (15-PGDH)
numbering), is often found in a conserved YXXXK pattern.
In addition to the Tyr and Lys, there is often an
upstream Ser (Ser-138, 15-PGDH numbering) and/or an Asn
(Asn-107, 15-PGDH numbering) or additional Ser,
contributing to the active site. Substrates for these
enzymes include sugars, steroids, alcohols, and aromatic
compounds. The standard reaction mechanism is a proton
relay involving the conserved Tyr and Lys, as well as
Asn (or Ser). Some SDR family members, including 17
beta-hydroxysteroid dehydrogenase contain an additional
helix-turn-helix motif that is not generally found among
SDRs.

>gnl|CDD|187611 cd05353, hydroxyacyl-CoA-like_DH_SDR_c-like, (3R)-hydroxyacyl-CoA
dehydrogenase-like, classical(c)-like SDRs. Beta
oxidation of fatty acids in eukaryotes occurs by a
four-reaction cycle, that may take place in mitochondria
or in peroxisomes. (3R)-hydroxyacyl-CoA dehydrogenase is
part of rat peroxisomal multifunctional MFE-2, it is a
member of the NAD-dependent SDRs, but contains an
additional small C-terminal domain that completes the
active site pocket and participates in dimerization. The
atypical, additional C-terminal extension allows for
more extensive dimerization contact than other SDRs.
MFE-2 catalyzes the second and third reactions of the
peroxisomal beta oxidation cycle. Proteins in this
subgroup have a typical catalytic triad, but have a His
in place of the usual upstream Asn. This subgroup also
contains members identified as 17-beta-hydroxysteroid
dehydrogenases, including human peroxisomal
17-beta-hydroxysteroid dehydrogenase type 4 (17beta-HSD
type 4, aka MFE-2, encoded by HSD17B4 gene) which is
involved in fatty acid beta-oxidation and steroid
metabolism. This subgroup also includes two SDR domains
of the Neurospora crassa and Saccharomyces cerevisiae
multifunctional beta-oxidation protein (MFP, aka Fox2).
SDRs are a functionally diverse family of
oxidoreductases that have a single domain with a
structurally conserved Rossmann fold (alpha/beta folding
pattern with a central beta-sheet), an NAD(P)(H)-binding
region, and a structurally diverse C-terminal region.
Classical SDRs are typically about 250 residues long,
while extended SDRS are approximately 350 residues.
Sequence identity between different SDR enzymes are
typically in the 15-30% range, but the enzymes share the
Rossmann fold NAD-binding motif and characteristic
NAD-binding and catalytic sequence patterns. These
enzymes have a 3-glycine N-terminal NAD(P)(H)-binding
pattern (typically, TGxxxGxG in classical SDRs and
TGxxGxxG in extended SDRs), while substrate binding is
in the C-terminal region. A critical catalytic Tyr
residue (Tyr-151, human 15-hydroxyprostaglandin
dehydrogenase (15-PGDH) numbering), is often found in a
conserved YXXXK pattern. In addition to the Tyr and Lys,
there is often an upstream Ser (Ser-138, 15-PGDH
numbering) and/or an Asn (Asn-107, 15-PGDH numbering) or
additional Ser, contributing to the active site.
Substrates for these enzymes include sugars, steroids,
alcohols, and aromatic compounds. The standard reaction
mechanism is a proton relay involving the conserved Tyr
and Lys, as well as Asn (or Ser). Some SDR family
members, including 17 beta-hydroxysteroid dehydrogenase
contain an additional helix-turn-helix motif that is not
generally found among SDRs.

>gnl|CDD|187634 cd08929, SDR_c4, classical (c) SDR, subgroup 4. This subgroup has
a canonical active site tetrad and a typical Gly-rich
NAD-binding motif. SDRs are a functionally diverse
family of oxidoreductases that have a single domain with
a structurally conserved Rossmann fold (alpha/beta
folding pattern with a central beta-sheet), an
NAD(P)(H)-binding region, and a structurally diverse
C-terminal region. Classical SDRs are typically about
250 residues long, while extended SDRs are approximately
350 residues. Sequence identity between different SDR
enzymes are typically in the 15-30% range, but the
enzymes share the Rossmann fold NAD-binding motif and
characteristic NAD-binding and catalytic sequence
patterns. These enzymes catalyze a wide range of
activities including the metabolism of steroids,
cofactors, carbohydrates, lipids, aromatic compounds,
and amino acids, and act in redox sensing. Classical
SDRs have an TGXXX[AG]XG cofactor binding motif and a
YXXXK active site motif, with the Tyr residue of the
active site motif serving as a critical catalytic
residue (Tyr-151, human 15-hydroxyprostaglandin
dehydrogenase (15-PGDH) numbering). In addition to the
Tyr and Lys, there is often an upstream Ser (Ser-138,
15-PGDH numbering) and/or an Asn (Asn-107, 15-PGDH
numbering) contributing to the active site; while
substrate binding is in the C-terminal region, which
determines specificity. The standard reaction mechanism
is a 4-pro-S hydride transfer and proton relay involving
the conserved Tyr and Lys, a water molecule stabilized
by Asn, and nicotinamide. Extended SDRs have additional
elements in the C-terminal region, and typically have a
TGXXGXXG cofactor binding motif. Complex (multidomain)
SDRs such as ketoreductase domains of fatty acid
synthase have a GGXGXXG NAD(P)-binding motif and an
altered active site motif (YXXXN). Fungal type ketoacyl
reductases have a TGXXXGX(1-2)G NAD(P)-binding motif.
Some atypical SDRs have lost catalytic activity and/or
have an unusual NAD(P)-binding motif and missing or
unusual active site residues. Reactions catalyzed within
the SDR family include isomerization, decarboxylation,
epimerization, C=N bond reduction, dehydratase activity,
dehalogenation, Enoyl-CoA reduction, and
carbonyl-alcohol oxidoreduction.

classical (c) SDRs. Sorbitol 6-phosphate dehydrogenase
(SDH, aka glucitol 6-phosphate dehydrogenase) catalyzes
the NAD-dependent interconversion of D-fructose
6-phosphate to D-sorbitol 6-phosphate. SDH is a member
of the classical SDRs, with the characteristic catalytic
tetrad, but without a complete match to the typical
NAD-binding motif. SDRs are a functionally diverse
family of oxidoreductases that have a single domain with
a structurally conserved Rossmann fold (alpha/beta
folding pattern with a central beta-sheet), an
NAD(P)(H)-binding region, and a structurally diverse
C-terminal region. Classical SDRs are typically about
250 residues long, while extended SDRs are approximately
350 residues. Sequence identity between different SDR
enzymes are typically in the 15-30% range, but the
enzymes share the Rossmann fold NAD-binding motif and
characteristic NAD-binding and catalytic sequence
patterns. These enzymes catalyze a wide range of
activities including the metabolism of steroids,
cofactors, carbohydrates, lipids, aromatic compounds,
and amino acids, and act in redox sensing. Classical
SDRs have an TGXXX[AG]XG cofactor binding motif and a
YXXXK active site motif, with the Tyr residue of the
active site motif serving as a critical catalytic
residue (Tyr-151, human 15-hydroxyprostaglandin
dehydrogenase (15-PGDH) numbering). In addition to the
Tyr and Lys, there is often an upstream Ser (Ser-138,
15-PGDH numbering) and/or an Asn (Asn-107, 15-PGDH
numbering) contributing to the active site; while
substrate binding is in the C-terminal region, which
determines specificity. The standard reaction mechanism
is a 4-pro-S hydride transfer and proton relay involving
the conserved Tyr and Lys, a water molecule stabilized
by Asn, and nicotinamide. Extended SDRs have additional
elements in the C-terminal region, and typically have a
TGXXGXXG cofactor binding motif. Complex (multidomain)
SDRs such as ketoreductase domains of fatty acid
synthase have a GGXGXXG NAD(P)-binding motif and an
altered active site motif (YXXXN). Fungal type ketoacyl
reductases have a TGXXXGX(1-2)G NAD(P)-binding motif.
Some atypical SDRs have lost catalytic activity and/or
have an unusual NAD(P)-binding motif and missing or
unusual active site residues. Reactions catalyzed within
the SDR family include isomerization, decarboxylation,
epimerization, C=N bond reduction, dehydratase activity,
dehalogenation, Enoyl-CoA reduction, and
carbonyl-alcohol oxidoreduction.

>gnl|CDD|187612 cd05354, SDR_c7, classical (c) SDR, subgroup 7. These proteins are
members of the classical SDR family, with a canonical
active site triad (and also an active site Asn) and a
typical Gly-rich NAD-binding motif. SDRs are a
functionally diverse family of oxidoreductases that have
a single domain with a structurally conserved Rossmann
fold (alpha/beta folding pattern with a central
beta-sheet), an NAD(P)(H)-binding region, and a
structurally diverse C-terminal region. Classical SDRs
are typically about 250 residues long, while extended
SDRS are approximately 350 residues. Sequence identity
between different SDR enzymes are typically in the
15-30% range, but the enzymes share the Rossmann fold
NAD-binding motif and characteristic NAD-binding and
catalytic sequence patterns. These enzymes have a
3-glycine N-terminal NAD(P)(H)-binding pattern
(typically, TGxxxGxG in classical SDRs and TGxxGxxG in
extended SDRs), while substrate binding is in the
C-terminal region. A critical catalytic Tyr residue
(Tyr-151, human 15-hydroxyprostaglandin dehydrogenase
(15-PGDH) numbering), is often found in a conserved
YXXXK pattern. In addition to the Tyr and Lys, there is
often an upstream Ser (Ser-138, 15-PGDH numbering)
and/or an Asn (Asn-107, 15-PGDH numbering) or additional
Ser, contributing to the active site. Substrates for
these enzymes include sugars, steroids, alcohols, and
aromatic compounds. The standard reaction mechanism is a
proton relay involving the conserved Tyr and Lys, as
well as Asn (or Ser). Some SDR family members, including
17 beta-hydroxysteroid dehydrogenase contain an
additional helix-turn-helix motif that is not generally
found among SDRs.

(3alpha_HSD), classical (c) SDRs. Bacterial
3-alpha_HSD, which catalyzes the NAD-dependent
oxidoreduction of hydroxysteroids, is a dimeric member
of the classical SDR family. SDRs are a functionally
diverse family of oxidoreductases that have a single
domain with a structurally conserved Rossmann fold
(alpha/beta folding pattern with a central beta-sheet),
an NAD(P)(H)-binding region, and a structurally diverse
C-terminal region. Classical SDRs are typically about
250 residues long, while extended SDRs are approximately
350 residues. Sequence identity between different SDR
enzymes are typically in the 15-30% range, but the
enzymes share the Rossmann fold NAD-binding motif and
characteristic NAD-binding and catalytic sequence
patterns. These enzymes catalyze a wide range of
activities including the metabolism of steroids,
cofactors, carbohydrates, lipids, aromatic compounds,
and amino acids, and act in redox sensing. Classical
SDRs have an TGXXX[AG]XG cofactor binding motif and a
YXXXK active site motif, with the Tyr residue of the
active site motif serving as a critical catalytic
residue (Tyr-151, human 15-hydroxyprostaglandin

Tyr and Lys, there is often an upstream Ser (Ser-138,
15-PGDH numbering) and/or an Asn (Asn-107, 15-PGDH
numbering) contributing to the active site; while
substrate binding is in the C-terminal region, which
determines specificity. The standard reaction mechanism
is a 4-pro-S hydride transfer and proton relay involving
the conserved Tyr and Lys, a water molecule stabilized
by Asn, and nicotinamide. Extended SDRs have additional
elements in the C-terminal region, and typically have a
TGXXGXXG cofactor binding motif. Complex (multidomain)
SDRs such as ketoreductase domains of fatty acid
synthase have a GGXGXXG NAD(P)-binding motif and an
altered active site motif (YXXXN). Fungal type ketoacyl
reductases have a TGXXXGX(1-2)G NAD(P)-binding motif.
Some atypical SDRs have lost catalytic activity and/or
have an unusual NAD(P)-binding motif and missing or
unusual active site residues. Reactions catalyzed within
the SDR family include isomerization, decarboxylation,
epimerization, C=N bond reduction, dehydratase activity,
dehalogenation, Enoyl-CoA reduction, and
carbonyl-alcohol oxidoreduction.

>gnl|CDD|212495 cd09807, retinol-DH_like_SDR_c, retinol dehydrogenases
(retinol-DHs), classical (c) SDRs. Classical SDR-like
subgroup containing retinol-DHs and related proteins.
Retinol is processed by a medium chain alcohol
dehydrogenase followed by retinol-DHs. Proteins in this
subfamily share the glycine-rich NAD-binding motif of
the classical SDRs, have a partial match to the
canonical active site tetrad, but lack the typical
active site Ser. This subgroup includes the human
proteins: retinol dehydrogenase -12, -13 ,and -14. SDRs
are a functionally diverse family of oxidoreductases
that have a single domain with a structurally conserved
Rossmann fold (alpha/beta folding pattern with a central
beta-sheet), an NAD(P)(H)-binding region, and a
structurally diverse C-terminal region. Classical SDRs
are typically about 250 residues long, while extended
SDRs are approximately 350 residues. Sequence identity
between different SDR enzymes are typically in the
15-30% range, but the enzymes share the Rossmann fold
NAD-binding motif and characteristic NAD-binding and
catalytic sequence patterns. These enzymes catalyze a
wide range of activities including the metabolism of
steroids, cofactors, carbohydrates, lipids, aromatic
compounds, and amino acids, and act in redox sensing.
Classical SDRs have an TGXXX[AG]XG cofactor binding
motif and a YXXXK active site motif, with the Tyr
residue of the active site motif serving as a critical
catalytic residue (Tyr-151, human
15-hydroxyprostaglandin dehydrogenase (15-PGDH)
numbering). In addition to the Tyr and Lys, there is
often an upstream Ser (Ser-138, 15-PGDH numbering)
and/or an Asn (Asn-107, 15-PGDH numbering) contributing
to the active site; while substrate binding is in the
C-terminal region, which determines specificity. The
standard reaction mechanism is a 4-pro-S hydride
transfer and proton relay involving the conserved Tyr
and Lys, a water molecule stabilized by Asn, and
nicotinamide. Extended SDRs have additional elements in
the C-terminal region, and typically have a TGXXGXXG
cofactor binding motif. Complex (multidomain) SDRs such
as ketoreductase domains of fatty acid synthase have a
GGXGXXG NAD(P)-binding motif and an altered active site
motif (YXXXN). Fungal type ketoacyl reductases have a
TGXXXGX(1-2)G NAD(P)-binding motif. Some atypical SDRs
have lost catalytic activity and/or have an unusual
NAD(P)-binding motif and missing or unusual active site
residues. Reactions catalyzed within the SDR family
include isomerization, decarboxylation, epimerization,
C=N bond reduction, dehydratase activity,
dehalogenation, Enoyl-CoA reduction, and
carbonyl-alcohol oxidoreduction.

reductase is an enzyme used by trypanosomatids
(including Trypanosoma cruzi and Leishmania major) to
obtain reduced pteridines by salvage rather than
biosynthetic pathways. Enzymes in T. cruzi described as
pteridine reductase 1 (PTR1) and pteridine reductase 2
(PTR2) have different activity profiles. PTR1 is more
active with with fully oxidized biopterin and folate
than with reduced forms, while PTR2 reduces
dihydrobiopterin and dihydrofolate but not oxidized
pteridines. T. cruzi PTR1 and PTR2 are more similar to
each other in sequence than either is to the pteridine
reductase of Leishmania major, and all are included in
this family.

>gnl|CDD|187619 cd05361, haloalcohol_DH_SDR_c-like, haloalcohol dehalogenase,
classical (c) SDRs. Dehalogenases cleave carbon-halogen
bonds. Haloalcohol dehalogenase show low sequence
similarity to short-chain dehydrogenases/reductases
(SDRs). Like the SDRs, haloalcohol dehalogenases have a
conserved catalytic triad (Ser-Tyr-Lys/Arg), and form a
Rossmann fold. However, the normal classical SDR
NAD(P)-binding motif (TGXXGXG) and NAD-binding function
is replaced with a halide binding site, allowing the
enzyme to catalyze a dehalogenation reaction. SDRs are a
functionally diverse family of oxidoreductases that have
a single domain with a structurally conserved Rossmann
fold (alpha/beta folding pattern with a central
beta-sheet), an NAD(P)(H)-binding region, and a
structurally diverse C-terminal region. Classical SDRs
are typically about 250 residues long, while extended
SDRs are approximately 350 residues. Sequence identity
between different SDR enzymes are typically in the
15-30% range, but the enzymes share the Rossmann fold
NAD-binding motif and characteristic NAD-binding and
catalytic sequence patterns. These enzymes catalyze a
wide range of activities including the metabolism of
steroids, cofactors, carbohydrates, lipids, aromatic
compounds, and amino acids, and act in redox sensing.
Classical SDRs have an TGXXX[AG]XG cofactor binding
motif and a YXXXK active site motif, with the Tyr
residue of the active site motif serving as a critical
catalytic residue (Tyr-151, human
15-hydroxyprostaglandin dehydrogenase (15-PGDH)
numbering). In addition to the Tyr and Lys, there is
often an upstream Ser (Ser-138, 15-PGDH numbering)
and/or an Asn (Asn-107, 15-PGDH numbering) contributing
to the active site; while substrate binding is in the
C-terminal region, which determines specificity. The
standard reaction mechanism is a 4-pro-S hydride
transfer and proton relay involving the conserved Tyr
and Lys, a water molecule stabilized by Asn, and
nicotinamide. Extended SDRs have additional elements in
the C-terminal region, and typically have a TGXXGXXG
cofactor binding motif. Complex (multidomain) SDRs such
as ketoreductase domains of fatty acid synthase have a
GGXGXXG NAD(P)-binding motif and an altered active site
motif (YXXXN). Fungal type ketoacyl reductases have a
TGXXXGX(1-2)G NAD(P)-binding motif. Some atypical SDRs
have lost catalytic activity and/or have an unusual
NAD(P)-binding motif and missing or unusual active site
residues. Reactions catalyzed within the SDR family
include isomerization, decarboxylation, epimerization,
C=N bond reduction, dehydratase activity,
dehalogenation, Enoyl-CoA reduction, and
carbonyl-alcohol oxidoreduction.

>gnl|CDD|187535 cd02266, SDR, Short-chain dehydrogenases/reductases (SDR). SDRs
are a functionally diverse family of oxidoreductases
that have a single domain with a structurally conserved
Rossmann fold (alpha/beta folding pattern with a central
beta-sheet), an NAD(P)(H)-binding region, and a
structurally diverse C-terminal region. Classical SDRs
are typically about 250 residues long, while extended
SDRs are approximately 350 residues. Sequence identity
between different SDR enzymes are typically in the
15-30% range, but the enzymes share the Rossmann fold
NAD-binding motif and characteristic NAD-binding and
catalytic sequence patterns. These enzymes catalyze a
wide range of activities including the metabolism of
steroids, cofactors, carbohydrates, lipids, aromatic
compounds, and amino acids, and act in redox sensing.
Classical SDRs have an TGXXX[AG]XG cofactor binding
motif and a YXXXK active site motif, with the Tyr
residue of the active site motif serving as a critical
catalytic residue (Tyr-151, human prostaglandin
dehydrogenase (PGDH) numbering). In addition to the Tyr
and Lys, there is often an upstream Ser (Ser-138, PGDH
numbering) and/or an Asn (Asn-107, PGDH numbering)
contributing to the active site; while substrate binding
is in the C-terminal region, which determines
specificity. The standard reaction mechanism is a
4-pro-S hydride transfer and proton relay involving the
conserved Tyr and Lys, a water molecule stabilized by
Asn, and nicotinamide. Extended SDRs have additional
elements in the C-terminal region, and typically have a
TGXXGXXG cofactor binding motif. Complex (multidomain)
SDRs such as ketoreductase (KR) domains of fatty acid
synthase have a GGXGXXG NAD(P)-binding motif and an
altered active site motif (YXXXN). Fungal type KRs have
a TGXXXGX(1-2)G NAD(P)-binding motif. Some atypical SDRs
have lost catalytic activity and/or have an unusual
NAD(P)-binding motif and missing or unusual active site
residues. Reactions catalyzed within the SDR family
include isomerization, decarboxylation, epimerization,
C=N bond reduction, dehydratase activity,
dehalogenation, Enoyl-CoA reduction, and
carbonyl-alcohol oxidoreduction.

pattern with a central beta-sheet), an NAD(P)(H)-binding
region, and a structurally diverse C-terminal region.
Classical SDRs are typically about 250 residues long,
while extended SDRs are approximately 350 residues.
Sequence identity between different SDR enzymes are
typically in the 15-30% range, but the enzymes share the
Rossmann fold NAD-binding motif and characteristic
NAD-binding and catalytic sequence patterns. These
enzymes catalyze a wide range of activities including
the metabolism of steroids, cofactors, carbohydrates,
lipids, aromatic compounds, and amino acids, and act in
redox sensing. Classical SDRs have an TGXXX[AG]XG
cofactor binding motif and a YXXXK active site motif,
with the Tyr residue of the active site motif serving as
a critical catalytic residue (Tyr-151, human
15-hydroxyprostaglandin dehydrogenase (15-PGDH)
numbering). In addition to the Tyr and Lys, there is
often an upstream Ser (Ser-138, 15-PGDH numbering)
and/or an Asn (Asn-107, 15-PGDH numbering) contributing
to the active site; while substrate binding is in the
C-terminal region, which determines specificity. The
standard reaction mechanism is a 4-pro-S hydride
transfer and proton relay involving the conserved Tyr
and Lys, a water molecule stabilized by Asn, and
nicotinamide. Extended SDRs have additional elements in
the C-terminal region, and typically have a TGXXGXXG
cofactor binding motif. Complex (multidomain) SDRs such
as ketoreductase domains of fatty acid synthase have a
GGXGXXG NAD(P)-binding motif and an altered active site
motif (YXXXN). Fungal type ketoacyl reductases have a
TGXXXGX(1-2)G NAD(P)-binding motif. Some atypical SDRs
have lost catalytic activity and/or have an unusual
NAD(P)-binding motif and missing or unusual active site
residues. Reactions catalyzed within the SDR family
include isomerization, decarboxylation, epimerization,
C=N bond reduction, dehydratase activity,
dehalogenation, Enoyl-CoA reduction, and
carbonyl-alcohol oxidoreduction.

SDRs. Ketoreductase, a module of the multidomain
polyketide synthase (PKS), has 2 subdomains, each
corresponding to a SDR family monomer. The C-terminal
subdomain catalyzes the NADPH-dependent reduction of the
beta-carbonyl of a polyketide to a hydroxyl group, a
step in the biosynthesis of polyketides, such as
erythromycin. The N-terminal subdomain, an interdomain
linker, is a truncated Rossmann fold which acts to
stabilizes the catalytic subdomain. Unlike typical SDRs,
the isolated domain does not oligomerize but is composed
of 2 subdomains, each resembling an SDR monomer. The
active site resembles that of typical SDRs, except that
the usual positions of the catalytic Asn and Tyr are
swapped, so that the canonical YXXXK motif changes to
YXXXN. Modular PKSs are multifunctional structures in
which the makeup recapitulates that found in (and may
have evolved from) FAS. Polyketide synthesis also
proceeds via the addition of 2-carbon units as in fatty
acid synthesis. The complex SDR NADP-binding motif,
GGXGXXG, is often present, but is not strictly conserved
in each instance of the module. This subfamily includes
both KR domains of the Bacillus subtilis Pks J,-L, and
PksM, and all three KR domains of PksN, components of
the megacomplex bacillaene synthase, which synthesizes
the antibiotic bacillaene. SDRs are a functionally
diverse family of oxidoreductases that have a single
domain with a structurally conserved Rossmann fold
(alpha/beta folding pattern with a central beta-sheet),
an NAD(P)(H)-binding region, and a structurally diverse
C-terminal region. Classical SDRs are typically about
250 residues long, while extended SDRs are approximately
350 residues. Sequence identity between different SDR
enzymes are typically in the 15-30% range, but the
enzymes share the Rossmann fold NAD-binding motif and
characteristic NAD-binding and catalytic sequence
patterns. These enzymes catalyze a wide range of
activities including the metabolism of steroids,
cofactors, carbohydrates, lipids, aromatic compounds,
and amino acids, and act in redox sensing. Classical
SDRs have an TGXXX[AG]XG cofactor binding motif and a
YXXXK active site motif, with the Tyr residue of the
active site motif serving as a critical catalytic
residue (Tyr-151, human prostaglandin dehydrogenase
(PGDH) numbering). In addition to the Tyr and Lys, there
is often an upstream Ser (Ser-138, PGDH numbering)
and/or an Asn (Asn-107, PGDH numbering) contributing to
the active site; while substrate binding is in the
C-terminal region, which determines specificity. The
standard reaction mechanism is a 4-pro-S hydride
transfer and proton relay involving the conserved Tyr
and Lys, a water molecule stabilized by Asn, and
nicotinamide. Extended SDRs have additional elements in
the C-terminal region, and typically have a TGXXGXXG
cofactor binding motif. Complex (multidomain) SDRs such
as ketoreductase domains of fatty acid synthase have a
GGXGXXG NAD(P)-binding motif and an altered active site
motif (YXXXN). Fungal type KRs have a TGXXXGX(1-2)G
NAD(P)-binding motif. Some atypical SDRs have lost
catalytic activity and/or have an unusual NAD(P)-binding
motif and missing or unusual active site residues.
Reactions catalyzed within the SDR family include
isomerization, decarboxylation, epimerization, C=N bond
reduction, dehydratase activity, dehalogenation,
Enoyl-CoA reduction, and carbonyl-alcohol
oxidoreduction.

classical (c) SDRs. Tthb094 from Thermus Thermophilus
is a classical SDR which binds NADP. Members of this
subgroup contain the YXXXK active site characteristic of
SDRs. Also, an upstream Asn residue of the canonical
catalytic tetrad is partially conserved in this subgroup
of proteins of undetermined function. SDRs are a
functionally diverse family of oxidoreductases that have
a single domain with a structurally conserved Rossmann
fold (alpha/beta folding pattern with a central
beta-sheet), an NAD(P)(H)-binding region, and a
structurally diverse C-terminal region. Classical SDRs
are typically about 250 residues long, while extended
SDRs are approximately 350 residues. Sequence identity
between different SDR enzymes are typically in the
15-30% range, but the enzymes share the Rossmann fold
NAD-binding motif and characteristic NAD-binding and
catalytic sequence patterns. These enzymes catalyze a
wide range of activities including the metabolism of
steroids, cofactors, carbohydrates, lipids, aromatic
compounds, and amino acids, and act in redox sensing.
Classical SDRs have an TGXXX[AG]XG cofactor binding
motif and a YXXXK active site motif, with the Tyr
residue of the active site motif serving as a critical
catalytic residue (Tyr-151, human prostaglandin
dehydrogenase (PGDH) numbering). In addition to the Tyr
and Lys, there is often an upstream Ser (Ser-138, PGDH
numbering) and/or an Asn (Asn-107, PGDH numbering)
contributing to the active site; while substrate binding
is in the C-terminal region, which determines
specificity. The standard reaction mechanism is a
4-pro-S hydride transfer and proton relay involving the
conserved Tyr and Lys, a water molecule stabilized by
Asn, and nicotinamide. Extended SDRs have additional
elements in the C-terminal region, and typically have a
TGXXGXXG cofactor binding motif. Complex (multidomain)
SDRs such as ketoreductase domains of fatty acid
synthase have a GGXGXXG NAD(P)-binding motif and an
altered active site motif (YXXXN). Fungal type ketoacyl
reductases have a TGXXXGX(1-2)G NAD(P)-binding motif.
Some atypical SDRs have lost catalytic activity and/or
have an unusual NAD(P)-binding motif and missing or
unusual active site residues. Reactions catalyzed within
the SDR family include isomerization, decarboxylation,
epimerization, C=N bond reduction, dehydratase activity,
dehalogenation, Enoyl-CoA reduction, and

(FAS), complex (x) SDRs. Ketoreductase, a module of the
multidomain polyketide synthase (PKS), has 2 subdomains,
each corresponding to a SDR family monomer. The
C-terminal subdomain catalyzes the NADPH-dependent
reduction of the beta-carbonyl of a polyketide to a
hydroxyl group, a step in the biosynthesis of
polyketides, such as erythromycin. The N-terminal
subdomain, an interdomain linker, is a truncated
Rossmann fold which acts to stabilizes the catalytic
subdomain. Unlike typical SDRs, the isolated domain does
not oligomerize but is composed of 2 subdomains, each
resembling an SDR monomer. The active site resembles
that of typical SDRs, except that the usual positions of
the catalytic Asn and Tyr are swapped, so that the
canonical YXXXK motif changes to YXXXN. Modular PKSs are
multifunctional structures in which the makeup
recapitulates that found in (and may have evolved from)
FAS. In some instances, such as porcine FAS, an enoyl
reductase (ER) module is inserted between the
sub-domains. Fatty acid synthesis occurs via the
stepwise elongation of a chain (which is attached to
acyl carrier protein, ACP) with 2-carbon units.
Eukaryotic systems consist of large, multifunctional
synthases (type I) while bacterial, type II systems, use
single function proteins. Fungal fatty acid synthase
uses a dodecamer of 6 alpha and 6 beta subunits. In
mammalian type FAS cycles, ketoacyl synthase forms
acetoacetyl-ACP which is reduced by the NADP-dependent
beta-KR, forming beta-hydroxyacyl-ACP, which is in turn
dehydrated by dehydratase to a beta-enoyl intermediate,
which is reduced by NADP-dependent beta-ER. Polyketide
synthesis also proceeds via the addition of 2-carbon
units as in fatty acid synthesis. The complex SDR
NADP-binding motif, GGXGXXG, is often present, but is
not strictly conserved in each instance of the module.
SDRs are a functionally diverse family of
oxidoreductases that have a single domain with a
structurally conserved Rossmann fold (alpha/beta folding
pattern with a central beta-sheet), an NAD(P)(H)-binding
region, and a structurally diverse C-terminal region.
Classical SDRs are typically about 250 residues long,
while extended SDRs are approximately 350 residues.
Sequence identity between different SDR enzymes are
typically in the 15-30% range, but the enzymes share the
Rossmann fold NAD-binding motif and characteristic
NAD-binding and catalytic sequence patterns. These
enzymes catalyze a wide range of activities including
the metabolism of steroids, cofactors, carbohydrates,
lipids, aromatic compounds, and amino acids, and act in
redox sensing. Classical SDRs have an TGXXX[AG]XG
cofactor binding motif and a YXXXK active site motif,
with the Tyr residue of the active site motif serving as
a critical catalytic residue (Tyr-151, human
prostaglandin dehydrogenase (PGDH) numbering). In
addition to the Tyr and Lys, there is often an upstream
Ser (Ser-138, PGDH numbering) and/or an Asn (Asn-107,
PGDH numbering) contributing to the active site; while
substrate binding is in the C-terminal region, which
determines specificity. The standard reaction mechanism
is a 4-pro-S hydride transfer and proton relay involving
the conserved Tyr and Lys, a water molecule stabilized
by Asn, and nicotinamide. Extended SDRs have additional
elements in the C-terminal region, and typically have a
TGXXGXXG cofactor binding motif. Complex (multidomain)
SDRs such as ketoreductase domains of fatty acid
synthase have a GGXGXXG NAD(P)-binding motif and an
altered active site motif (YXXXN). Fungal type KRs have
a TGXXXGX(1-2)G NAD(P)-binding motif. Some atypical SDRs
have lost catalytic activity and/or have an unusual
NAD(P)-binding motif and missing or unusual active site
residues. Reactions catalyzed within the SDR family
include isomerization, decarboxylation, epimerization,
C=N bond reduction, dehydratase activity,
dehalogenation, Enoyl-CoA reduction, and
carbonyl-alcohol oxidoreduction.

There are distinct enzymes that catalyze Pchlide

>gnl|CDD|187658 cd08955, KR_2_FAS_SDR_x, beta-ketoacyl reductase (KR) domain of
fatty acid synthase (FAS), subgroup 2, complex (x).
Ketoreductase, a module of the multidomain polyketide
synthase, has 2 subdomains, each corresponding to a
short-chain dehydrogenases/reductase (SDR) family
monomer. The C-terminal subdomain catalyzes the
NADPH-dependent reduction of the beta-carbonyl of a
polyketide to a hydroxyl group, a step in the
biosynthesis of polyketides, such as erythromycin. The
N-terminal subdomain, an interdomain linker, is a
truncated Rossmann fold which acts to stabilizes the
catalytic subdomain. Unlike typical SDRs, the isolated
domain does not oligomerizes but is composed of 2
subdomains, each resembling an SDR monomer. In some
instances, as in porcine FAS, an enoyl reductase (a
Rossman fold NAD binding domain of the MDR family)
module is inserted between the sub-domains. The active
site resembles that of typical SDRs, except that the
usual positions of the catalytic asparagine and tyrosine
are swapped, so that the canonical YXXXK motif changes
to YXXXN. Modular polyketide synthases are
multifunctional structures in which the makeup
recapitulates that found in (and may have evolved from)
fatty acid synthase. In some instances, such as
porcine FAS , an enoyl reductase module is inserted
between the sub-domains. Fatty acid synthesis occurs via
the stepwise elongation of a chain (which is attached to
acyl carrier protein, ACP) with 2-carbon units.
Eukaryotic systems consists of large, multifunctional

Polyketide syntheses also proceeds via the addition of

is not strictly conserved in each instance of the
module. This subfamily includes the KR domain of the
Lyngbya majuscule Jam J, -K, and #L which are encoded
on the jam gene cluster and are involved in the
synthesis of the Jamaicamides (neurotoxins); Lyngbya
majuscule Jam P belongs to a different KR_FAS_SDR_x
subfamily. SDRs are a functionally diverse family of

a functionally diverse family of oxidoreductases that
have a single domain with a structurally conserved
Rossmann fold, an NAD(P)(H)-binding region, and a
structurally diverse C-terminal region. Sequence
identity between different SDR enzymes is typically in
the 15-30% range; they catalyze a wide range of
activities including the metabolism of steroids,
cofactors, carbohydrates, lipids, aromatic compounds,
and amino acids, and act in redox sensing. Classical
SDRs have an TGXXX[AG]XG cofactor binding motif and a
YXXXK active site motif, with the Tyr residue of the
active site motif serving as a critical catalytic
residue (Tyr-151, human 15-hydroxyprostaglandin
dehydrogenase numbering). In addition to the Tyr and
Lys, there is often an upstream Ser and/or an Asn,
contributing to the active site; while substrate
binding is in the C-terminal region, which determines
specificity. The standard reaction mechanism is a
4-pro-S hydride transfer and proton relay involving the
conserved Tyr and Lys, a water molecule stabilized by
Asn, and nicotinamide. In addition to the Rossmann fold
core region typical of all SDRs, extended SDRs have a
less conserved C-terminal extension of approximately
100 amino acids, and typically have a TGXXGXXG cofactor
binding motif. Complex (multidomain) SDRs such as
ketoreductase domains of fatty acid synthase have a
GGXGXXG NAD(P)-binding motif and an altered active site
motif (YXXXN). Fungal type ketoacyl reductases have a
TGXXXGX(1-2)G NAD(P)-binding motif.

binding domain. NADP-dependent H4MPT DH catalyzes the
dehydrogenation of methylene- H4MPT and
methylene-tetrahydrofolate (H4F) with NADP+ as
cofactor. H4F and H4MPT are both cofactors that carry
the one-carbon units between the formyl and methyl

analogous to each other with respect to the pterin
moiety, but each has distinct side chain. H4MPT is
present only in anaerobic methanogenic archaea and
aerobic methylotrophic proteobacteria. H4MPT seems to
have evolved independently from H4F and functions as a
distinct carrier in C1 metabolism. Amino acid DH-like

phenylalanine DHs, methylene tetrahydrofolate DH,
methylene-tetrahydromethanopterin DH,
methylene-tetrahydropholate DH/cyclohydrolase,
Shikimate DH-like proteins, malate oxidoreductases, and

100 amino acids. Extended SDRs are a diverse collection
of proteins, and include isomerases, epimerases,
oxidoreductases, and lyases; they typically have a
TGXXGXXG cofactor binding motif. SDRs are a
functionally diverse family of oxidoreductases that
have a single domain with a structurally conserved
Rossmann fold, an NAD(P)(H)-binding region, and a
structurally diverse C-terminal region. Sequence
identity between different SDR enzymes is typically in
the 15-30% range; they catalyze a wide range of
activities including the metabolism of steroids,
cofactors, carbohydrates, lipids, aromatic compounds,
and amino acids, and act in redox sensing. Classical
SDRs have an TGXXX[AG]XG cofactor binding motif and a
YXXXK active site motif, with the Tyr residue of the
active site motif serving as a critical catalytic
residue (Tyr-151, human 15-hydroxyprostaglandin
dehydrogenase numbering). In addition to the Tyr and
Lys, there is often an upstream Ser and/or an Asn,
contributing to the active site; while substrate
binding is in the C-terminal region, which determines
specificity. The standard reaction mechanism is a
4-pro-S hydride transfer and proton relay involving the
conserved Tyr and Lys, a water molecule stabilized by
Asn, and nicotinamide. Atypical SDRs generally lack the
catalytic residues characteristic of the SDRs, and
their glycine-rich NAD(P)-binding motif is often
different from the forms normally seen in classical or
extended SDRs. Complex (multidomain) SDRs such as
ketoreductase domains of fatty acid synthase have a
GGXGXXG NAD(P)-binding motif and an altered active site
motif (YXXXN). Fungal type ketoacyl reductases have a
TGXXXGX(1-2)G NAD(P)-binding motif.

oxidoreductase, a medium chain dehydrogenase/reductase
family member, acts in the apoptotic pathway. PIG3
reduces ortho-quinones, but its apoptotic activity has
been attributed to oxidative stress generation, since
overexpression of PIG3 accumulates reactive oxygen
species. PIG3 resembles the MDR family member quinone
reductases, which catalyze the reduction of quinone to
hydroxyquinone. NAD(P)(H)-dependent oxidoreductases are
the major enzymes in the interconversion of alcohols and
aldehydes or ketones. Alcohol dehydrogenase in the
liver converts ethanol and NAD+ to acetaldehyde and
NADH, while in yeast and some other microorganisms ADH
catalyzes the conversion acetaldehyde to ethanol in
alcoholic fermentation. ADH is a member of the medium
chain alcohol dehydrogenase family (MDR), which has a
NAD(P)(H)-binding domain in a Rossmann fold of a
beta-alpha form. The NAD(H)-binding region is comprised
of 2 structurally similar halves, each of which contacts
a mononucleotide. A GxGxxG motif after the first
mononucleotide contact half allows the close contact of
the coenzyme with the ADH backbone. The N-terminal
catalytic domain has a distant homology to GroES.
These proteins typically form dimers (typically higher
plants, mammals) or tetramers (yeast, bacteria), and
have 2 tightly bound zinc atoms per subunit, a catalytic
zinc at the active site, and a structural zinc in a lobe
of the catalytic domain. NAD(H) binding occurs in the
cleft between the catalytic and coenzyme-binding domains
at the active site, and coenzyme binding induces a
conformational closing of this cleft. Coenzyme binding
typically precedes and contributes to substrate binding.
In human ADH catalysis, the zinc ion helps coordinate
the alcohol, followed by deprotonation of a histidine,
the ribose of NAD, a serine, then the alcohol, which
allows the transfer of a hydride to NAD+, creating NADH
and a zinc-bound aldehyde or ketone. In yeast and some
bacteria, the active site zinc binds an aldehyde,
polarizing it, and leading to the reverse reaction.

fungal-type multidomain FAS alpha chain, and the single
domain daunorubicin C-13 ketoreductase. Fungal-type FAS
is a heterododecameric FAS composed of alpha and beta
multifunctional polypeptide chains. The KR, an SDR
family member is located centrally in the alpha chain.
KR catalyzes the NADP-dependent reduction of
ketoacyl-ACP to hydroxyacyl-ACP. KR shares the critical
active site Tyr of the classical SDR and has partial
identity of the active site tetrad, but the upstream Asn
is replaced in KR by Met. As in other SDRs, there is a
glycine rich NAD(P)-binding motif, but the pattern found
in KR does not match the classical SDRs, and is not
strictly conserved within this group. Daunorubicin is a
clinically important therapeutic compound used in some
cancer treatments. Single domain daunorubicin C-13
ketoreductase is member of the classical SDR family with
a canonical glycine-rich NAD(P)-binding motif, but
lacking a complete match to the active site tetrad
characteristic of this group. The critical Tyr, plus the
Lys and upstream Asn are present, but the catalytic Ser
is replaced, generally by Gln. SDRs are a functionally
diverse family of oxidoreductases that have a single
domain with a structurally conserved Rossmann fold
(alpha/beta folding pattern with a central beta-sheet),
an NAD(P)(H)-binding region, and a structurally diverse
C-terminal region. Classical SDRs are typically about
250 residues long, while extended SDRs are approximately
350 residues. Sequence identity between different SDR
enzymes are typically in the 15-30% range, but the
enzymes share the Rossmann fold NAD-binding motif and
characteristic NAD-binding and catalytic sequence
patterns. These enzymes catalyze a wide range of
activities including the metabolism of steroids,
cofactors, carbohydrates, lipids, aromatic compounds,
and amino acids, and act in redox sensing. Classical
SDRs have an TGXXX[AG]XG cofactor binding motif and a
YXXXK active site motif, with the Tyr residue of the
active site motif serving as a critical catalytic
residue (Tyr-151, human prostaglandin dehydrogenase
(PGDH) numbering). In addition to the Tyr and Lys, there
is often an upstream Ser (Ser-138, PGDH numbering)
and/or an Asn (Asn-107, PGDH numbering) contributing to
the active site; while substrate binding is in the
C-terminal region, which determines specificity. The
standard reaction mechanism is a 4-pro-S hydride
transfer and proton relay involving the conserved Tyr
and Lys, a water molecule stabilized by Asn, and
nicotinamide. Extended SDRs have additional elements in
the C-terminal region, and typically have a TGXXGXXG
cofactor binding motif. Complex (multidomain) SDRs such
as ketoreductase domains of fatty acid synthase have a
GGXGXXG NAD(P)-binding motif and an altered active site
motif (YXXXN). Fungal type KRs have a TGXXXGX(1-2)G
NAD(P)-binding motif. Some atypical SDRs have lost
catalytic activity and/or have an unusual NAD(P)-binding
motif and missing or unusual active site residues.
Reactions catalyzed within the SDR family include
isomerization, decarboxylation, epimerization, C=N bond
reduction, dehydratase activity, dehalogenation,
Enoyl-CoA reduction, and carbonyl-alcohol

respiratory chains of bacteria and mitochondria, while
soluble QOR acts to protect from toxic quinones (e.g.

>gnl|CDD|187653 cd08950, KR_fFAS_SDR_c_like, ketoacyl reductase (KR) domain of
fungal-type fatty acid synthase (fFAS), classical
(c)-like SDRs. KR domain of fungal-type fatty acid
synthase (FAS), type I. Fungal-type FAS is a
heterododecameric FAS composed of alpha and beta
multifunctional polypeptide chains. The KR, an SDR
family member, is located centrally in the alpha chain.
KR catalyzes the NADP-dependent reduction of
ketoacyl-ACP to hydroxyacyl-ACP. KR shares the critical
active site Tyr of the Classical SDR and has partial
identity of the active site tetrad, but the upstream
Asn is replaced in KR by Met. As in other SDRs, there
is a glycine rich NAD-binding motif, but the pattern
found in KR does not match the classical SDRs, and is
not strictly conserved within this group. SDRs are a
functionally diverse family of oxidoreductases that
have a single domain with a structurally conserved
Rossmann fold (alpha/beta folding pattern with a
central beta-sheet), an NAD(P)(H)-binding region, and a
structurally diverse C-terminal region. Classical SDRs
are typically about 250 residues long, while extended
SDRs are approximately 350 residues. Sequence identity
between different SDR enzymes are typically in the
15-30% range, but the enzymes share the Rossmann fold
NAD-binding motif and characteristic NAD-binding and
catalytic sequence patterns. These enzymes catalyze a
wide range of activities including the metabolism of
steroids, cofactors, carbohydrates, lipids, aromatic
compounds, and amino acids, and act in redox sensing.
Classical SDRs have an TGXXX[AG]XG cofactor binding
motif and a YXXXK active site motif, with the Tyr
residue of the active site motif serving as a critical
catalytic residue (Tyr-151, human prostaglandin
dehydrogenase (PGDH) numbering). In addition to the Tyr
and Lys, there is often an upstream Ser (Ser-138, PGDH
numbering) and/or an Asn (Asn-107, PGDH numbering)
contributing to the active site; while substrate
binding is in the C-terminal region, which determines
specificity. The standard reaction mechanism is a
4-pro-S hydride transfer and proton relay involving the
conserved Tyr and Lys, a water molecule stabilized by
Asn, and nicotinamide. Extended SDRs have additional
elements in the C-terminal region, and typically have a
TGXXGXXG cofactor binding motif. Complex (multidomain)
SDRs such as ketoreductase domains of fatty acid
synthase have a GGXGXXG NAD(P)-binding motif and an
altered active site motif (YXXXN). Fungal type KRs have
a TGXXXGX(1-2)G NAD(P)-binding motif. Some atypical
SDRs have lost catalytic activity and/or have an
unusual NAD(P)-binding motif and missing or unusual
active site residues. Reactions catalyzed within the
SDR family include isomerization, decarboxylation,
epimerization, C=N bond reduction, dehydratase
activity, dehalogenation, Enoyl-CoA reduction, and
carbonyl-alcohol oxidoreduction.

of 7alpha-hydroxylated sterol intermediates, an early

putative quinone oxidoreductases (QOR). QOR catalyzes
the conversion of a quinone + NAD(P)H to a hydroquinone
+ NAD(P)+. Quinones are cyclic diones derived from
aromatic compounds. Membrane bound QOR actin the
respiratory chains of bacteria and mitochondria, while
soluble QOR acts to protect from toxic quinones (e.g.
DT-diaphorase) or as a soluble eye-lens protein in some
vertebrates (e.g. zeta-crystalin). QOR reduces quinones
through a semi-quinone intermediate via a
NAD(P)H-dependent single electron transfer. QOR is a
member of the medium chain dehydrogenase/reductase
family, but lacks the zinc-binding sites of the
prototypical alcohol dehydrogenases of this group.
NAD(P)(H)-dependent oxidoreductases are the major
enzymes in the interconversion of alcohols and
aldehydes, or ketones. Alcohol dehydrogenase in the
liver converts ethanol and NAD+ to acetaldehyde and
NADH, while in yeast and some other microorganisms ADH
catalyzes the conversion acetaldehyde to ethanol in
alcoholic fermentation. ADH is a member of the medium
chain alcohol dehydrogenase family (MDR), which has a
NAD(P)(H)-binding domain in a Rossmann fold of a
beta-alpha form. The NAD(H)-binding region is comprised
of 2 structurally similar halves, each of which contacts
a mononucleotide. A GxGxxG motif after the first
mononucleotide contact half allows the close contact of
the coenzyme with the ADH backbone. The N-terminal
catalytic domain has a distant homology to GroES. These
proteins typically form dimers (typically higher plants,
mammals) or tetramers (yeast, bacteria), and have 2
tightly bound zinc atoms per subunit, a catalytic zinc
at the active site and a structural zinc in a lobe of
the catalytic domain. NAD(H) binding occurs in the
cleft between the catalytic and coenzyme-binding
domains at the active site, and coenzyme binding induces
a conformational closing of this cleft. Coenzyme binding
typically precedes and contributes to substrate binding.
In human ADH catalysis, the zinc ion helps coordinate
the alcohol, followed by deprotonation of a histidine,
the ribose of NAD, a serine, then the alcohol, which
allows the transfer of a hydride to NAD+, creating NADH
and a zinc-bound aldehyde or ketone. In yeast and some
bacteria, the active site zinc binds an aldehyde,
polarizing it, and leading to the reverse reaction.

quinone reductase activity (QOR). Zeta-crystallin is a
eye lens protein with NADP-dependent quinone reductase
activity (QOR). It has been cited as a structural
component in mammalian eyes, but also has homology to
quinone reductases in unrelated species. QOR catalyzes
the conversion of a quinone and NAD(P)H to a
hydroquinone and NAD(P+. Quinones are cyclic diones
derived from aromatic compounds. Membrane bound QOR acts
in the respiratory chains of bacteria and mitochondria,
while soluble QOR acts to protect from toxic quinones
(e.g. DT-diaphorase) or as a soluble eye-lens protein in
some vertebrates (e.g. zeta-crystalin). QOR reduces
quinones through a semi-quinone intermediate via a
NAD(P)H-dependent single electron transfer. QOR is a
member of the medium chain dehydrogenase/reductase
family, but lacks the zinc-binding sites of the
prototypical alcohol dehydrogenases of this group.
Alcohol dehydrogenase in the liver converts ethanol and
NAD+ to acetaldehyde and NADH, while in yeast and some
other microorganisms ADH catalyzes the conversion
acetaldehyde to ethanol in alcoholic fermentation. ADH
is a member of the medium chain alcohol dehydrogenase
family (MDR), which has a NAD(P)(H)-binding domain in a
Rossmann fold of a beta-alpha form. The NAD(H)-binding
region is comprised of 2 structurally similar halves,
each of which contacts a mononucleotide. The N-terminal
catalytic domain has a distant homology to GroES. These
proteins typically form dimers (typically higher plants,
mammals) or tetramers (yeast, bacteria), and have 2
tightly bound zinc atoms per subunit, a catalytic zinc
at the active site, and a structural zinc in a lobe of
the catalytic domain. NAD(H)-binding occurs in the
cleft between the catalytic and coenzyme-binding domains
at the active site, and coenzyme binding induces a
conformational closing of this cleft. Coenzyme binding
typically precedes and contributes to substrate binding.
In human ADH catalysis, the zinc ion helps coordinate
the alcohol, followed by deprotonation of a histidine,
the ribose of NAD, a serine, then the alcohol, which
allows the transfer of a hydride to NAD+, creating NADH
and a zinc-bound aldehyde or ketone. In yeast and some
bacteria, the active site zinc binds an aldehyde,
polarizing it, and leading to the reverse reaction.

proteins are atypical SDRs. They have a glycine-rich
NAD(P)-binding motif similar to the typical SDRs,
GXXGXXG, and have the YXXXK active site motif (though
not the other residues of the SDR tetrad). Members
identified include NDUFA9 (mitochondrial) and putative
nucleoside-diphosphate-sugar epimerase. Atypical SDRs
generally lack the catalytic residues characteristic of
the SDRs, and their glycine-rich NAD(P)-binding motif
is often different from the forms normally seen in
classical or extended SDRs. Atypical SDRs include
biliverdin IX beta reductase (BVR-B,aka flavin
reductase), NMRa (a negative transcriptional regulator
of various fungi), progesterone 5-beta-reductase like
proteins, phenylcoumaran benzylic ether and
pinoresinol-lariciresinol reductases, phenylpropene
synthases, eugenol synthase, triphenylmethane
reductase, isoflavone reductases, and others. SDRs are
a functionally diverse family of oxidoreductases that
have a single domain with a structurally conserved
Rossmann fold, an NAD(P)(H)-binding region, and a
structurally diverse C-terminal region. Sequence
identity between different SDR enzymes is typically in
the 15-30% range; they catalyze a wide range of
activities including the metabolism of steroids,
cofactors, carbohydrates, lipids, aromatic compounds,
and amino acids, and act in redox sensing. Classical
SDRs have an TGXXX[AG]XG cofactor binding motif and a
YXXXK active site motif, with the Tyr residue of the
active site motif serving as a critical catalytic
residue (Tyr-151, human 15-hydroxyprostaglandin
dehydrogenase numbering). In addition to the Tyr and
Lys, there is often an upstream Ser and/or an Asn,
contributing to the active site; while substrate
binding is in the C-terminal region, which determines
specificity. The standard reaction mechanism is a
4-pro-S hydride transfer and proton relay involving the
conserved Tyr and Lys, a water molecule stabilized by
Asn, and nicotinamide. In addition to the Rossmann fold
core region typical of all SDRs, extended SDRs have a
less conserved C-terminal extension of approximately
100 amino acids, and typically have a TGXXGXXG cofactor
binding motif. Complex (multidomain) SDRs such as
ketoreductase domains of fatty acid synthase have a
GGXGXXG NAD(P)-binding motif and an altered active site
motif (YXXXN). Fungal type ketoacyl reductases have a
TGXXXGX(1-2)G NAD(P)-binding motif.

>gnl|CDD|187557 cd05246, dTDP_GD_SDR_e, dTDP-D-glucose 4,6-dehydratase, extended
(e) SDRs. This subgroup contains dTDP-D-glucose
4,6-dehydratase and related proteins, members of the
extended-SDR family, with the characteristic Rossmann
fold core region, active site tetrad and NAD(P)-binding
motif. dTDP-D-glucose 4,6-dehydratase is closely
related to other sugar epimerases of the SDR family.
dTDP-D-dlucose 4,6,-dehydratase catalyzes the second of
four steps in the dTDP-L-rhamnose pathway (the
dehydration of dTDP-D-glucose to
dTDP-4-keto-6-deoxy-D-glucose) in the synthesis of
L-rhamnose, a cell wall component of some pathogenic
bacteria. In many gram negative bacteria, L-rhamnose is
an important constituent of lipopoylsaccharide
O-antigen. The larger N-terminal portion of
dTDP-D-Glucose 4,6-dehydratase forms a Rossmann fold
NAD-binding domain, while the C-terminus binds the
sugar substrate. Extended SDRs are distinct from
classical SDRs. In addition to the Rossmann fold
(alpha/beta folding pattern with a central beta-sheet)
core region typical of all SDRs, extended SDRs have a
less conserved C-terminal extension of approximately
100 amino acids. Extended SDRs are a diverse collection
of proteins, and include isomerases, epimerases,
oxidoreductases, and lyases; they typically have a
TGXXGXXG cofactor binding motif. SDRs are a
functionally diverse family of oxidoreductases that
have a single domain with a structurally conserved
Rossmann fold, an NAD(P)(H)-binding region, and a
structurally diverse C-terminal region. Sequence
identity between different SDR enzymes is typically in
the 15-30% range; they catalyze a wide range of
activities including the metabolism of steroids,
cofactors, carbohydrates, lipids, aromatic compounds,
and amino acids, and act in redox sensing. Classical
SDRs have an TGXXX[AG]XG cofactor binding motif and a
YXXXK active site motif, with the Tyr residue of the
active site motif serving as a critical catalytic
residue (Tyr-151, human 15-hydroxyprostaglandin
dehydrogenase numbering). In addition to the Tyr and
Lys, there is often an upstream Ser and/or an Asn,
contributing to the active site; while substrate
binding is in the C-terminal region, which determines
specificity. The standard reaction mechanism is a
4-pro-S hydride transfer and proton relay involving the
conserved Tyr and Lys, a water molecule stabilized by
Asn, and nicotinamide. Atypical SDRs generally lack the
catalytic residues characteristic of the SDRs, and
their glycine-rich NAD(P)-binding motif is often
different from the forms normally seen in classical or
extended SDRs. Complex (multidomain) SDRs such as
ketoreductase domains of fatty acid synthase have a
GGXGXXG NAD(P)-binding motif and an altered active site
motif (YXXXN). Fungal type ketoacyl reductases have a
TGXXXGX(1-2)G NAD(P)-binding motif.

>gnl|CDD|176179 cd05195, enoyl_red, enoyl reductase of polyketide synthase.
Putative enoyl reductase of polyketide synthase.
Polyketide synthases produce polyketides in step by step
mechanism that is similar to fatty acid synthesis. Enoyl
reductase reduces a double to single bond. Erythromycin
is one example of a polyketide generated by 3 complex
enzymes (megasynthases). 2-enoyl thioester reductase
(ETR) catalyzes the NADPH-dependent dependent conversion
of trans-2-enoyl acyl carrier protein/coenzyme A
(ACP/CoA) to acyl-(ACP/CoA) in fatty acid synthesis.
2-enoyl thioester reductase activity has been linked in
Candida tropicalis as essential in maintaining
mitiochondrial respiratory function. This ETR family is
a part of the medium chain dehydrogenase/reductase
family, but lack the zinc coordination sites
characteristic of the alcohol dehydrogenases in this
family. NAD(P)(H)-dependent oxidoreductases are the
major enzymes in the interconversion of alcohols and
aldehydes or ketones. Alcohol dehydrogenase in the liver
converts ethanol and NAD+ to acetaldehyde and NADH,
while in yeast and some other microorganisms ADH
catalyzes the conversion acetaldehyde to ethanol in
alcoholic fermentation. ADH is a member of the medium
chain alcohol dehydrogenase family (MDR), which has a
NAD(P)(H)-binding domain in a Rossmann fold of a
beta-alpha form. The NAD(H)-binding region is comprised
of 2 structurally similar halves, each of which contacts
a mononucleotide. The N-terminal catalytic domain has a
distant homology to GroES. These proteins typically
form dimers (typically higher plants, mammals) or
tetramers (yeast, bacteria), and have 2 tightly bound
zinc atoms per subunit, a catalytic zinc at the active
site, and a structural zinc in a lobe of the catalytic
domain. NAD(H) binding occurs in the cleft between the
catalytic and coenzyme-binding domains, at the active
site, and coenzyme binding induces a conformational
closing of this cleft. Coenzyme binding typically
precedes and contributes to substrate binding.

subfamily G of the ATP-binding cassette superfamily.
ABCG transporters are involved in eye pigment (EP)
precursor transport, regulation of lipid-trafficking
mechanisms, and pleiotropic drug resistance (DR). DR is
a well-described phenomenon occurring in fungi and
shares several similarities with processes in bacteria
and higher eukaryotes. Compared to other members of the
ABC transporter subfamilies, the ABCG transporter family
is composed of proteins that have an ATP-binding
cassette domain at the N-terminus and a TM
(transmembrane) domain at the C-terminus.
