>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|212491 cd05233, SDR_c, classical (c) SDRs. 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
carbonyl-alcohol oxidoreduction.

>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.

>gnl|CDD|187624 cd05366, meso-BDH-like_SDR_c, meso-2,3-butanediol
dehydrogenase-like, classical (c) SDRs. 2,3-butanediol
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.

>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

SDRs. Human 11beta_HSD1 catalyzes the NADP(H)-dependent
interconversion of cortisone and cortisol. This subgroup
also includes human dehydrogenase/reductase SDR family
member 7C (DHRS7C) and DHRS7B. These proteins have the
GxxxGxG nucleotide binding motif and S-Y-K catalytic
triad characteristic of the SDRs, but have an atypical
C-terminal domain that contributes to homodimerization
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.

>gnl|CDD|187639 cd08934, CAD_SDR_c, clavulanic acid dehydrogenase (CAD), classical
(c) SDR. CAD catalyzes the NADP-dependent reduction of
clavulanate-9-aldehyde to clavulanic acid, a
beta-lactamase inhibitor. 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.

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

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

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

protein [ACP] reductase (BKR)-like, SDR. This subgroup
resembles the SDR family, but does not have a perfect
match to the NAD-binding motif or the catalytic tetrad
characteristic of the SDRs. It includes the SDRs, Q9HYA2
from Pseudomonas aeruginosa PAO1 and APE0912 from
Aeropyrum pernix K1. 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

>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|187605 cd05347, Ga5DH-like_SDR_c, gluconate 5-dehydrogenase (Ga5DH)-like,
classical (c) SDRs. Ga5DH catalyzes the NADP-dependent
conversion of carbon source D-gluconate and
5-keto-D-gluconate. This SDR subgroup has a classical
Gly-rich NAD(P)-binding motif and a conserved active
site tetrad pattern. However, it has been proposed that
Arg104 (Streptococcus suis Ga5DH numbering), as well as
an active site Ca2+, play a critical role in catalysis.
In addition to Ga5DHs this subgroup contains Erwinia
chrysanthemi KduD which is involved in pectin
degradation, and is a putative
2,5-diketo-3-deoxygluconate dehydrogenase. 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|187600 cd05341, 3beta-17beta-HSD_like_SDR_c, 3beta17beta hydroxysteroid
dehydrogenase-like, classical (c) SDRs. This subgroup
includes members identified as 3beta17beta
hydroxysteroid dehydrogenase, 20beta hydroxysteroid
dehydrogenase, and R-alcohol dehydrogenase. These
proteins exhibit the canonical active site tetrad and
glycine rich NAD(P)-binding motif of the classical SDRs.
17beta-dehydrogenases are a group of isozymes that
catalyze activation and inactivation of estrogen and
androgens, and include members of the 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 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.

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.

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|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.

while extended SDRS are approximately 350 residues.

and related proteins, classical (c) SDR. These proteins
include members identified as KDSR, ribitol type
dehydrogenase, and others. The group shows strong
conservation of the active site tetrad and glycine rich
NAD-binding motif of the classical SDRs. 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

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.

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.

(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

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

>gnl|CDD|187631 cd05373, SDR_c10, classical (c) SDR, subgroup 10. This subgroup
resembles the classical SDRs, but has an incomplete
match to the canonical glycine rich NAD-binding motif
and lacks the typical active site tetrad (instead of the
critical active site Tyr, it has Phe, but contains the
nearby Lys). 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|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.

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.

HSDL2 and related proteins. These are members of the

Sequence identity between different SDR enzymes are

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

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

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.

>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.

(aka 1,2-dihydroxycyclohexa-3,5-diene-1-carboxylate

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

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. Note: removed :

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|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.

>gnl|CDD|187636 cd08931, SDR_c9, classical (c) SDR, subgroup 9. This subgroup has
the canonical active site tetrad and NAD-binding motif
of the classical SDRs. 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|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
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 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

family) member 1 (DHRS1) -like, classical (c) 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
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.

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.

[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

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

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

these enzymes include sugars, steroids, alcohols, and
aromatic compounds. The standard reaction mechanism is a

>gnl|CDD|187663 cd09762, HSDL2_SDR_c, human hydroxysteroid dehydrogenase-like
protein 2 (HSDL2), classical (c) SDRs. This subgroup
includes human HSDL2 and related protens. 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. 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.

>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.

>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.

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.

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
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.

clinically important therapeutic compound used in some
cancer treatments. 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
oxidoreduction.

classical (c) SDRs. Lin1944 protein from Listeria
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
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
carbonyl-alcohol oxidoreduction.

cis-biphenyl-2,3-dihydrodiol-2,3-dehydrogenase (BphB) is
a classical SDR, it is of particular importance for its

dehydrogenases. 2-Hydroxyacid dehydrogenases catalyze
the conversion of a wide variety of D-2-hydroxy acids to
their corresponding keto acids. The general mechanism is
(R)-lactate + acceptor to pyruvate + reduced acceptor.
Formate/glycerate and related dehydrogenases of the
D-specific 2-hydroxyacid dehydrogenase superfamily
include groups such as formate dehydrogenase, glycerate
dehydrogenase, L-alanine dehydrogenase, and
S-adenosylhomocysteine hydrolase. Despite often low
sequence identity, these proteins typically have a
characteristic arrangement of 2 similar subdomains of
the alpha/beta Rossmann fold NAD+ binding form. The NAD+
binding domain is inserted within the linear sequence of
the mostly N-terminal catalytic domain, which has a
similar domain structure to the internal NAD binding
domain. Structurally, these domains are connected by
extended alpha helices and create a cleft in which NAD
is bound, primarily to the C-terminal portion of the 2nd
(internal) domain. Some related proteins have similar
structural subdomain but with a tandem arrangement of
the catalytic and NAD-binding subdomains in the linear
sequence. While many members of this family are dimeric,
alanine DH is hexameric and phosphoglycerate DH is
tetrameric.

(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.

classical (c) SDRs. Dihydropteridine reductase is an
NAD-binding protein related to the SDRs. It converts
dihydrobiopterin into tetrahydrobiopterin, a cofactor
necessary in catecholamines synthesis. Dihydropteridine
reductase has the YXXXK of these tyrosine-dependent
oxidoreductases, but lacks the typical upstream Asn and
Ser catalytic residues. SDRs are a functionally diverse
family of oxidoreductases that have a single domain with

folding pattern with a central beta-sheet), an
NAD(P)(H)-binding region, and a structurally diverse

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.

(e) SDRs. UDP-Glcnac inverting 4,6-dehydratase was
identified in Helicobacter pylori as the hexameric flaA1
gene product (FlaA1). FlaA1 is hexameric, possesses
UDP-GlcNAc-inverting 4,6-dehydratase activity, and
catalyzes the first step in the creation of a

Although this subgroup has the NADP-binding motif
characteristic of extended SDRs, its members tend to
have a Met substituted for the active site Tyr found in
most SDR families. 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.

dehydrogenase, N-benzyl-3-pyrrolidinol dehydrogenase,
and other MDR family members. This group contains
enzymes of the zinc-dependent alcohol dehydrogenase
family, including members (aka MDR) identified as
6-hydroxycyclohex-1-ene-1-carboxyl-CoA dehydrogenase and
N-benzyl-3-pyrrolidinol dehydrogenase.
6-hydroxycyclohex-1-ene-1-carboxyl-CoA dehydrogenase
catalyzes the conversion of
6-Hydroxycyclohex-1-enecarbonyl-CoA and NAD+ to
6-Ketoxycyclohex-1-ene-1-carboxyl-CoA,NADH, and H+. This
group displays the characteristic catalytic and
structural zinc sites of the zinc-dependent alcohol
dehydrogenases. 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 have 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.

(MDR)/zinc-dependent alcohol dehydrogenase-like family.
This group is a member of the medium chain
dehydrogenases/reductase (MDR)/zinc-dependent alcohol
dehydrogenase-like family, but lacks the zinc-binding
sites of the zinc-dependent alcohol dehydrogenases. The
medium chain dehydrogenases/reductase
(MDR)/zinc-dependent alcohol dehydrogenase-like family,
which contains the zinc-dependent alcohol dehydrogenase
(ADH-Zn) and related proteins, is a diverse group of
proteins related to the first identified member, class I
mammalian ADH. MDRs display a broad range of activities
and are distinguished from the smaller short chain
dehydrogenases (~ 250 amino acids vs. the ~ 350 amino
acids of the MDR). The MDR proteins have 2 domains: a
C-terminal NAD(P)-binding Rossmann fold domain of a
beta-alpha form and an N-terminal catalytic domain with
distant homology to GroES. The MDR group contains a
host of activities, including the founding alcohol
dehydrogenase (ADH), quinone reductase, sorbitol
dehydrogenase, formaldehyde dehydrogenase, butanediol
DH, ketose reductase, cinnamyl reductase, and numerous
others. The zinc-dependent alcohol dehydrogenases (ADHs)
catalyze the NAD(P)(H)-dependent interconversion of
alcohols to aldehydes or ketones. Active site zinc has
a catalytic role, while structural zinc aids in
stability. ADH-like proteins typically form dimers
(typically higher plants, mammals) or tetramers (yeast,
bacteria), and generally have 2 tightly bound zinc atoms
per subunit. The active site zinc is coordinated by a
histidine, two cysteines, and a water molecule. The
second zinc seems to play a structural role, affects
subunit interactions, and is typically coordinated by 4
cysteines.

NAD-binding and catalytic domains.
D-Erythronate-4-phosphate Dehydrogenase (E. coli gene
PdxB), a D-specific 2-hydroxyacid dehydrogenase family
member, catalyzes the NAD-dependent oxidation of
erythronate-4-phosphate, which is followed by
transamination to form 4-hydroxy-L-threonine-4-phosphate
within the de novo biosynthesis pathway of vitamin B6.
D-Erythronate-4-phosphate dehydrogenase has the common
architecture shared with D-isomer specific 2-hydroxyacid
dehydrogenases but contains an additional C-terminal
dimerization domain in addition to an NAD-binding domain
and the "lid" domain. The lid domain corresponds to the
catalytic domain of phosphoglycerate dehydrogenase and
other proteins of the D-isomer specific 2-hydroxyacid
dehydrogenase family, which include groups such as
formate dehydrogenase, glycerate dehydrogenase,
L-alanine dehydrogenase, and S-adenosylhomocysteine
hydrolase. Despite often low sequence identity, these
proteins typically have a characteristic arrangement of
2 similar subdomains of the alpha/beta Rossmann fold
NAD+ binding form. The NAD+ binding domain is inserted
within the linear sequence of the mostly N-terminal
catalytic domain, which has a similar domain structure
to the internal NAD binding domain. Structurally, these
domains are connected by extended alpha helices and
create a cleft in which NAD is bound, primarily to the
C-terminal portion of the 2nd (internal) domain. Some
related proteins have similar structural subdomain but
with a tandem arrangement of the catalytic and
NAD-binding subdomains in the linear sequence.

describes Pseudomonas denitrificans CobT gene product,
which is a cobalt chelatase subunit that functions in
cobalamin biosynthesis. Cobalamin (vitamin B12) can be
synthesized via several pathways, including an aerobic
pathway (found in Pseudomonas denitrificans) and an
anaerobic pathway (found in P. shermanii and Salmonella
typhimurium). These pathways differ in the point of
cobalt insertion during corrin ring formation. There are
apparently a number of variations on these two pathways,
where the major differences seem to be concerned with
the process of ring contraction. Confusion regarding the
functions of enzymes found in the aerobic vs. anaerobic
pathways has arisen because nonhomologous genes in these
different pathways were given the same gene symbols.
Thus, cobT in the aerobic pathway (P. denitrificans) is
not a homolog of cobT in the anaerobic pathway (S.
typhimurium). It should be noted that E. coli
synthesizes cobalamin only when it is supplied with the
precursor cobinamide, which is a complex intermediate.
Additionally, all E. coli cobalamin synthesis genes
(cobU, cobS and cobT) were named after their Salmonella
typhimurium homologs which function in the anaerobic
cobalamin synthesis pathway. This model describes the
aerobic cobalamin pathway Pseudomonas denitrificans CobT
gene product, which is a cobalt chelatase subunit, with
a MW ~70 kDa. The aerobic pathway cobalt chelatase is a
heterotrimeric, ATP-dependent enzyme that catalyzes
cobalt insertion during cobalamin biosynthesis. The
other two subunits are the P. denitrificans CobS
(TIGR01650) and CobN (pfam02514 CobN/Magnesium
Chelatase) proteins. To avoid potential confusion with
the nonhomologous Salmonella typhimurium/E.coli cobT
gene product, the P. denitrificans gene symbol is not
used in the name of this model [Biosynthesis of
cofactors, prosthetic groups, and carriers, Heme,

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.

cofactors, carbohydrates, lipids, aromatic compounds,

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

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

ketoreductase domains of fatty acid synthase have a
GGXGXXG NAD(P)-binding motif and an altered active site

TGXXXGX(1-2)G NAD(P)-binding motif.

dTDP-6-deoxy-L-lyxo-4-hexulose reductase, an extended
SDR, synthesizes dTDP-L-rhamnose from
alpha-D-glucose-1-phosphate, providing the precursor
of L-rhamnose, an essential cell wall component of many
pathogenic bacteria. This subgroup has the
characteristic active site tetrad and NADP-binding

The human gene encoding MAT2B encodes two major
splicing variants which are induced in human cell liver
cancer and regulate HuR, an mRNA-binding protein which
stabilizes the mRNA of several cyclins, to affect cell
proliferation. Both MAT2B variants include this
extended SDR domain. 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

2-hydroxy acid dehydrogenase, Phosphoglycerate
Dehydrogenase, Lactate dehydrogenase, Thermostable
Phosphite Dehydrogenase, and Hydroxy(phenyl)pyruvate
reductase, among others, share a characteristic
arrangement of 2 similar subdomains of the alpha/beta
Rossmann fold NAD+ binding form. 2-hydroxyacid
dehydrogenases are enzymes that catalyze the conversion
of a wide variety of D-2-hydroxy acids to their
corresponding keto acids. The general mechanism is
(R)-lactate + acceptor to pyruvate + reduced acceptor.
The NAD+ binding domain is inserted within the linear
sequence of the mostly N-terminal catalytic domain,
which has a similar domain structure to the internal NAD
binding domain. Structurally, these domains are
connected by extended alpha helices and create a cleft
in which NAD is bound, primarily to the C-terminal
portion of the 2nd (internal) domain. Some related
proteins have similar structural subdomain but with a
tandem arrangement of the catalytic and NAD-binding
subdomains in the linear sequence. Formate dehydrogenase
(FDH) catalyzes the NAD+-dependent oxidation of formate
ion to carbon dioxide with the concomitant reduction of
NAD+ to NADH. FDHs of this family contain no metal ions
or prosthetic groups. Catalysis occurs though direct
transfer of hydride ion to NAD+ without the stages of
acid-base catalysis typically found in related
dehydrogenases. FDHs are found in all methylotrophic
microorganisms in energy production and in the stress
responses of plants. Formate/glycerate and related
dehydrogenases of the D-specific 2-hydroxyacid
dehydrogenase superfamily include groups such as formate
dehydrogenase, glycerate dehydrogenase, L-alanine
dehydrogenase, and S-Adenosylhomocysteine Hydrolase,
among others. While many members of this family are
dimeric, alanine DH is hexameric and phosphoglycerate DH
is tetrameric.

Class Sigma-like Glutathione S-transferases.
Glutathione S-transferase (GST) C-terminal domain
family, Class Sigma_like; composed of GSTs belonging to
class Sigma and similar proteins, including GSTs from
class Mu, Pi, and Alpha. GSTs are cytosolic dimeric
proteins involved in cellular detoxification by
catalyzing the conjugation of glutathione (GSH) with a
wide range of endogenous and xenobiotic alkylating
agents, including carcinogens, therapeutic drugs,
environmental toxins, and products of oxidative stress.
The GST fold contains an N-terminal thioredoxin-fold
domain and a C-terminal alpha helical domain, with an
active site located in a cleft between the two domains.
GSH binds to the N-terminal domain while the
hydrophobic substrate occupies a pocket in the
C-terminal domain. Vertebrate class Sigma GSTs are
characterized as GSH-dependent hematopoietic
prostaglandin (PG) D synthases and are responsible for
the production of PGD2 by catalyzing the isomerization
of PGH2. The functions of PGD2 include the maintenance
of body temperature, inhibition of platelet
aggregation, bronchoconstriction, vasodilation, and
mediation of allergy and inflammation. Other class
Sigma-like members include the class II insect GSTs,
S-crystallins from cephalopods, nematode-specific GSTs,
and 28-kDa GSTs from parasitic flatworms. Drosophila
GST2 is associated with indirect flight muscle and
exhibits preference for catalyzing GSH conjugation to
lipid peroxidation products, indicating an anti-oxidant
role. S-crystallin constitutes the major lens protein
in cephalopod eyes and is responsible for lens
transparency and proper refractive index. The 28-kDa
GST from Schistosoma is a multifunctional enzyme,
exhibiting GSH transferase, GSH peroxidase, and PGD2
synthase activities, and may play an important role in
host-parasite interactions. Members also include novel
GSTs from the fungus Cunninghamella elegans, designated
as class Gamma, and from the protozoan Blepharisma
japonicum, described as a light-inducible GST.

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.

(a) SDRs. This subgroup of extended SDR-like 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

>gnl|CDD|218904 pfam06123, CreD, Inner membrane protein CreD. This family consists
of several bacterial CreD or Cet inner membrane
proteins. Dominant mutations of the cet gene of
Escherichia coli result in tolerance to colicin E2 and
increased amounts of an inner membrane protein with an
Mr of 42,000. The cet gene is shown to be in the same
operon as the phoM gene, which is required in a phoR
background for expression of the structural gene for
alkaline phosphatase, phoA. Although the Cet protein is
not required for phoA expression, it has been suggested
that the Cet protein has an enhancing effect on the
transcription of phoA.

family members of unknown function have a glycine-rich

the extended SDRs, GXXGXXG. Generally, this group has
poor conservation of the active site tetrad, However,
individual sequences do contain matches to the YXXXK

>gnl|CDD|173798 cd05562, Peptidases_S53_like, Peptidase domain in the S53 family.
Members of the peptidase S53 (sedolisin) family include
endopeptidases and exopeptidases. The S53 family
contains a catalytic triad Glu/Asp/Ser with an
additional acidic residue Asp in the oxyanion hole,
similar to that of Asn in subtilisin. The stability of
these enzymes may be enhanced by calcium, some members
have been shown to bind up to 4 ions via binding sites
with different affinity. Some members of this clan
contain disulfide bonds. These enzymes can be intra- and
extracellular, some function at extreme temperatures and
pH values. Characterized sedolisins include Kumamolisin,
an extracellular calcium-dependent thermostable
endopeptidase from Bacillus. The enzyme is synthesized
with a 188 amino acid N-terminal preprotein region which
is cleaved after the extraction into the extracellular
space with low pH. One kumamolysin paralog,
kumamolisin-As, is believed to be a collagenase. TPP1 is
a serine protease that functions as a tripeptidyl
exopeptidase as well as an endopeptidase. Less is known
about PSCP from Pseudomonas which is thought to be an
aspartic proteinase.
