>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.

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

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
carbonyl-alcohol oxidoreduction.

contacts. 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.

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.

(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

>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
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 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

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

(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.

dehydrogenases (BDHs) catalyze the NAD+ dependent
conversion of 2,3-butanediol to acetonin; BDHs are
classified into types according to their
stereospecificity as to substrates and products.
Included in this subgroup are Klebsiella pneumonia
meso-BDH which catalyzes meso-2,3-butanediol to
D(-)-acetonin, and Corynebacterium glutamicum L-BDH
which catalyzes lX+)-2,3-butanediol to L(+)-acetonin.
This subgroup is comprised of classical SDRs with the
characteristic catalytic triad and 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.

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.

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

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

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,

>gnl|CDD|187618 cd05360, SDR_c3, classical (c) SDR, subgroup 3. These proteins are
members of the classical SDR family, with a canonical
active site triad (and also 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.

NAD-binding motif and the typical YXXXK active site

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).
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.

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
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.

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).

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

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.

(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
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

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.

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|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.

Innocua is a classical SDR, it contains a glycine-rich
motif similar to the canonical motif of the SDR
NAD(P)-binding site. However, the typical SDR active
site residues are absent 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

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
carbonyl-alcohol oxidoreduction.

[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.

Complex (multidomain) SDRs such as ketoreductase domains
of fatty acid synthase have a GGXGXXG NAD(P) binding

(retinol-DH), Light dependent Protochlorophyllide
(Pchlide) OxidoReductase (LPOR) and related proteins,
classical (c) SDRs. Classical SDR subgroup containing
retinol-DHs, LPORs, and related proteins. Retinol is
processed by a medium chain alcohol dehydrogenase
followed by retinol-DHs. Pchlide reductases act in
chlorophyll biosynthesis. There are distinct enzymes
that catalyze Pchlide reduction in light or dark
conditions. Light-dependent reduction is via an
NADP-dependent SDR, LPOR. 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, dehydrogenase/reductase
SDR family member (DHRS)-12 , -13 and -X (a DHRS on
chromosome X), and WWOX (WW domain-containing
oxidoreductase), as well as a Neurospora crassa SDR
encoded by the blue light inducible bli-4 gene. 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|187589 cd05328, 3alpha_HSD_SDR_c, alpha hydroxysteroid dehydrogenase
(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
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.

interconverts D-sorbitol (D-glucitol) and D-fructose,
but also interconverts L-iditol/L-sorbose and
galactitol/D-tagatose. SDH is NAD-dependent and is a

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
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|187656 cd08953, KR_2_SDR_x, ketoreductase (KR), subgroup 2, 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. 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.

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

These are members of the classical SDR family, with a

has been detected in many tissues, liver, heart,

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|187582 cd05274, KR_FAS_SDR_x, ketoreductase (KR) and fatty acid synthase
(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.

synthase PfaA. Members of the seed for this alignment
are involved in omega-3 polyunsaturated fatty acid
biosynthesis, such as the protein PfaA from the
eicosapentaenoic acid biosynthesis operon in
Photobacterium profundum strain SS9. PfaA is encoded
together with PfaB, PfaC, and PfaD, and the functions of
the individual polypeptides have not yet been described.
More distant homologs of PfaA, also included with the
reach of this model, appear to be involved in
polyketide-like biosynthetic mechanisms of
polyunsaturated fatty acid biosynthesis, an alternative
to the more familiar iterated mechanism of chain
extension and desaturation, and in most cases are encoded
near genes for homologs of PfaB, PfaC, and/or PfaD.
