>gnl|CDD|187614 cd05356, 17beta-HSD1_like_SDR_c, 17-beta-hydroxysteroid
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.

>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.

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.

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

Sequence identity between different SDR enzymes are
typically in the 15-30% range, but the enzymes share the

enzymes catalyze a wide range of activities including
the metabolism of steroids, cofactors, carbohydrates,

standard reaction mechanism is a 4-pro-S hydride

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

>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.

SDRs. Human Mgc4172-like proteins, putative SDRs. These
proteins are members of the SDR family, with a canonical
active site tetrad and a typical Gly-rich NAD-binding
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|187584 cd05323, ADH_SDR_c_like, insect type alcohol dehydrogenase
(ADH)-like, classical (c) SDRs. This subgroup contains
insect type ADH, and 15-hydroxyprostaglandin
dehydrogenase (15-PGDH) type I; these proteins are
classical SDRs. ADH catalyzes the NAD+-dependent
oxidation of alcohols to aldehydes/ketones. This
subgroup is distinct from the zinc-dependent alcohol
dehydrogenases of the medium chain
dehydrogenase/reductase family, and evolved in fruit
flies to allow the digestion of fermenting fruit.
15-PGDH catalyzes the NAD-dependent interconversion of
(5Z,13E)-(15S)-11alpha,15-dihydroxy-9-oxoprost-13-enoate
and (5Z,13E)-11alpha-hydroxy-9,15-dioxoprost-13-enoate,
and has a typical SDR glycine-rich NAD-binding motif,
which is not fully present in ADH. SDRs are a
functionally diverse family of oxidoreductases that have
a single domain with a structurally conserved Rossmann
fold (alpha/beta folding pattern with a central
beta-sheet), an NAD(P)(H)-binding region, and a
structurally diverse C-terminal region. Classical SDRs
are typically about 250 residues long, while extended
SDRs are approximately 350 residues. Sequence identity
between different SDR enzymes are typically in the
15-30% range, but the enzymes share the Rossmann fold
NAD-binding motif and characteristic NAD-binding and
catalytic sequence patterns. These enzymes catalyze a
wide range of activities including the metabolism of
steroids, cofactors, carbohydrates, lipids, aromatic
compounds, and amino acids, and act in redox sensing.
Classical SDRs have an TGXXX[AG]XG cofactor binding
motif and a YXXXK active site motif, with the Tyr
residue of the active site motif serving as a critical
catalytic residue (Tyr-151, human
15-hydroxyprostaglandin dehydrogenase (15-PGDH)
numbering). In addition to the Tyr and Lys, there is
often an upstream Ser (Ser-138, 15-PGDH numbering)
and/or an Asn (Asn-107, 15-PGDH numbering) contributing
to the active site; while substrate binding is in the
C-terminal region, which determines specificity. The
standard reaction mechanism is a 4-pro-S hydride
transfer and proton relay involving the conserved Tyr
and Lys, a water molecule stabilized by Asn, and
nicotinamide. Extended SDRs have additional elements in
the C-terminal region, and typically have a TGXXGXXG
cofactor binding motif. Complex (multidomain) SDRs such
as ketoreductase domains of fatty acid synthase have a
GGXGXXG NAD(P)-binding motif and an altered active site
motif (YXXXN). Fungal type ketoacyl reductases have a
TGXXXGX(1-2)G NAD(P)-binding motif. Some atypical SDRs
have lost catalytic activity and/or have an unusual
NAD(P)-binding motif and missing or unusual active site
residues. Reactions catalyzed within the SDR family
include isomerization, decarboxylation, epimerization,
C=N bond reduction, dehydratase activity,
dehalogenation, Enoyl-CoA reduction, and
carbonyl-alcohol oxidoreduction.

A_reductase (ChcA)_like, classical (c) SDRs. This
subgroup contains classical SDR proteins, including
members identified as 1-cyclohexenylcarbonyl coenzyme A
reductase. ChcA of Streptomyces collinus is implicated
in the final reduction step of shikimic acid to
ansatrienin. ChcA shows sequence similarity to the SDR
family of NAD-binding proteins, but it lacks the
conserved Tyr of the characteristic catalytic site. This
subgroup also contains the NADH-dependent
enoyl-[acyl-carrier-protein(ACP)] reductase FabL from
Bacillus subtilis. This enzyme participates in bacterial
fatty acid synthesis, in type II fatty-acid synthases
and catalyzes the last step in each elongation cycle.
SDRs are a functionally diverse family of

while extended SDRS are approximately 350 residues.
Sequence identity between different SDR enzymes are

NAD-binding and catalytic sequence patterns. These
enzymes have a 3-glycine N-terminal NAD(P)(H)-binding

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

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.

(c) SDRs. GlcDH, is a tetrameric member of the SDR
family, it catalyzes the NAD(P)-dependent oxidation of
beta-D-glucose to D-glucono-delta-lactone. GlcDH has a
typical NAD-binding site glycine-rich pattern as well as
the canonical active site tetrad (YXXXK motif plus
upstream Ser and Asn). SDRs are a functionally diverse
family of oxidoreductases that have a single domain with
a structurally conserved Rossmann fold (alpha/beta
folding pattern with a central beta-sheet), an
NAD(P)(H)-binding region, and a structurally diverse
C-terminal region. Classical SDRs are typically about
250 residues long, while extended SDRS are approximately
350 residues. Sequence identity between different SDR
enzymes are typically in the 15-30% range, but the
enzymes share the Rossmann fold NAD-binding motif and
characteristic NAD-binding and catalytic sequence
patterns. These enzymes have a 3-glycine N-terminal
NAD(P)(H)-binding pattern (typically, TGxxxGxG in
classical SDRs and TGxxGxxG in extended SDRs), while
substrate binding is in the C-terminal region. A
critical catalytic Tyr residue (Tyr-151, human
15-hydroxyprostaglandin dehydrogenase (15-PGDH)
numbering), is often found in a conserved YXXXK pattern.
In addition to the Tyr and Lys, there is often an

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

>gnl|CDD|187649 cd08945, PKR_SDR_c, Polyketide ketoreductase, classical (c) SDR.
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.

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

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

>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.

reductase; they are members of the SDR family. XR,
catalyzes the NADP-dependent reduction of L-xyulose and
other sugars. Tetrameric mouse carbonyl reductase is
involved in the metabolism of biogenic and xenobiotic
carbonyl compounds. This subgroup also includes
tetrameric chicken liver D-erythrulose reductase, which

SDRs are a functionally diverse family of
oxidoreductases that have a single domain with a

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

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|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

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

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

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

represent acetoacetyl-CoA reductase, a member of the

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

>gnl|CDD|187586 cd05325, carb_red_sniffer_like_SDR_c, carbonyl reductase
sniffer-like, classical (c) SDRs. Sniffer is an
NADPH-dependent carbonyl reductase of the classical SDR
family. Studies in Drosophila melanogaster implicate
Sniffer in the prevention of neurodegeneration due to
aging and oxidative-stress. This subgroup also includes
Rhodococcus sp. AD45 IsoH, which is an NAD-dependent
1-hydroxy-2-glutathionyl-2-methyl-3-butene dehydrogenase
involved in isoprene metabolism, Aspergillus nidulans
StcE encoded by a gene which is part of a proposed
sterigmatocystin biosynthesis gene cluster, Bacillus
circulans SANK 72073 BtrF encoded by a gene found in the
butirosin biosynthesis gene cluster, and Aspergillus
parasiticus nor-1 involved in the biosynthesis of
aflatoxins. 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
dehydrogenase) catalyzes the NAD-dependent conversion of
1,2-dihydroxycyclohexa-3,4-diene carboxylate to a
catechol. This subgroup also contains Pseudomonas putida

>gnl|CDD|187613 cd05355, SDR_c1, classical (c) SDR, subgroup 1. 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.

17beta-hydroxysteroid dehydrogenase type 1 (type 1
17beta-HSD)-like, classical (c) SDRs.
17beta-hydroxysteroid dehydrogenases are a group of
isozymes that catalyze activation and inactivation of
estrogen and androgens. This classical SDR subgroup
includes human type 1 17beta-HSD, human retinol
dehydrogenase 8, zebrafish photoreceptor associated
retinol dehydrogenase type 2, and a chicken
ovary-specific 17beta-hydroxysteroid 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.

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

dehydrogenase. Members of this protein family are the
enzyme 2-hydroxycyclohexanecarboxyl-CoA dehydrogenase.
The enzymatic properties were confirmed experimentally
in Rhodopseudomonas palustris; the enzyme is
homotetrameric, and not sensitive to oxygen. This enzyme
is part of proposed pathway for degradation of
benzoyl-CoA to 3-hydroxypimeloyl-CoA that differs from
the analogous in Thauera aromatica. It also may occur in
degradation of the non-aromatic compound
cyclohexane-1-carboxylate.

>gnl|CDD|187665 cd09805, type2_17beta_HSD-like_SDR_c, human 17beta-hydroxysteroid
dehydrogenase type 2 (type 2 17beta-HSD)-like, classical
(c) SDRs. 17beta-hydroxysteroid dehydrogenases are a
group of isozymes that catalyze activation and
inactivation of estrogen and androgens. This
classical-SDR subgroup includes the human proteins: type
2 17beta-HSD, type 6 17beta-HSD, type 2 11beta-HSD,
dehydrogenase/reductase SDR family member 9,
short-chain dehydrogenase/reductase family 9C member 7,
3-hydroxybutyrate dehydrogenase type 1, and retinol
dehydrogenase 5. 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.

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.

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

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

>gnl|CDD|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.

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

>gnl|CDD|187646 cd08942, RhlG_SDR_c, RhlG and related beta-ketoacyl reductases,
classical (c) SDRs. Pseudomonas aeruginosa RhlG is an
SDR-family beta-ketoacyl reductase involved in
Rhamnolipid biosynthesis. RhlG is similar to but
distinct from the FabG family of beta-ketoacyl-acyl
carrier protein (ACP) of type II fatty acid synthesis.
RhlG and related proteins are classical SDRs, with a
canonical active site tetrad and glycine-rich
NAD(P)-binding motif. SDRs are a functionally diverse
family of oxidoreductases that have a single domain with
a structurally conserved Rossmann fold (alpha/beta
folding pattern with a central beta-sheet), an
NAD(P)(H)-binding region, and a structurally diverse
C-terminal region. Classical SDRs are typically about
250 residues long, while extended SDRs are approximately
350 residues. Sequence identity between different SDR
enzymes are typically in the 15-30% range, but the
enzymes share the Rossmann fold NAD-binding motif and
characteristic NAD-binding and catalytic sequence
patterns. These enzymes catalyze a wide range of
activities including the metabolism of steroids,
cofactors, carbohydrates, lipids, aromatic compounds,
and amino acids, and act in redox sensing. Classical
SDRs have an TGXXX[AG]XG cofactor binding motif and a
YXXXK active site motif, with the Tyr residue of the
active site motif serving as a critical catalytic
residue (Tyr-151, human 15-hydroxyprostaglandin
dehydrogenase (15-PGDH) numbering). In addition to the
Tyr and Lys, there is often an upstream Ser (Ser-138,
15-PGDH numbering) and/or an Asn (Asn-107, 15-PGDH
numbering) contributing to the active site; while
substrate binding is in the C-terminal region, which
determines specificity. The standard reaction mechanism
is a 4-pro-S hydride transfer and proton relay involving
the conserved Tyr and Lys, a water molecule stabilized
by Asn, and nicotinamide. Extended SDRs have additional
elements in the C-terminal region, and typically have a
TGXXGXXG cofactor binding motif. Complex (multidomain)
SDRs such as ketoreductase domains of fatty acid
synthase have a GGXGXXG NAD(P)-binding motif and an
altered active site motif (YXXXN). Fungal type ketoacyl
reductases have a TGXXXGX(1-2)G NAD(P)-binding motif.
Some atypical SDRs have lost catalytic activity and/or
have an unusual NAD(P)-binding motif and missing or
unusual active site residues. Reactions catalyzed within
the SDR family include isomerization, decarboxylation,
epimerization, C=N bond reduction, dehydratase activity,
dehalogenation, Enoyl-CoA reduction, and
carbonyl-alcohol oxidoreduction.

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

family member (DHRS)-12/FLJ13639-like, classical
(c)-like SDRs. Classical SDR-like subgroup containing
human DHRS-12/FLJ13639, the 36K protein of zebrafish CNS
myelin, and related proteins. DHRS-12/FLJ13639 is
expressed in neurons and oligodendrocytes in the human
cerebral cortex. Proteins in this subgroup 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. SDRs are a
functionally diverse family of oxidoreductases that have
a single domain with a structurally conserved Rossmann
fold (alpha/beta folding pattern with a central
beta-sheet), an NAD(P)(H)-binding region, and a
structurally diverse C-terminal region. Classical SDRs
are typically about 250 residues long, while extended
SDRs are approximately 350 residues. Sequence identity
between different SDR enzymes are typically in the
15-30% range, but the enzymes share the Rossmann fold
NAD-binding motif and characteristic NAD-binding and
catalytic sequence patterns. These enzymes catalyze a
wide range of activities including the metabolism of
steroids, cofactors, carbohydrates, lipids, aromatic
compounds, and amino acids, and act in redox sensing.
Classical SDRs have an TGXXX[AG]XG cofactor binding
motif and a YXXXK active site motif, with the Tyr
residue of the active site motif serving as a critical
catalytic residue (Tyr-151, human
15-hydroxyprostaglandin dehydrogenase (15-PGDH)
numbering). In addition to the Tyr and Lys, there is
often an upstream Ser (Ser-138, 15-PGDH numbering)
and/or an Asn (Asn-107, 15-PGDH numbering) contributing
to the active site; while substrate binding is in the
C-terminal region, which determines specificity. The
standard reaction mechanism is a 4-pro-S hydride
transfer and proton relay involving the conserved Tyr
and Lys, a water molecule stabilized by Asn, and
nicotinamide. Extended SDRs have additional elements in
the C-terminal region, and typically have a TGXXGXXG
cofactor binding motif. Complex (multidomain) SDRs such
as ketoreductase domains of fatty acid synthase have a
GGXGXXG NAD(P)-binding motif and an altered active site
motif (YXXXN). Fungal type ketoacyl reductases have a
TGXXXGX(1-2)G NAD(P)-binding motif. Some atypical SDRs
have lost catalytic activity and/or have an unusual
NAD(P)-binding motif and missing or unusual active site
residues. Reactions catalyzed within the SDR family
include isomerization, decarboxylation, epimerization,
C=N bond reduction, dehydratase activity,
dehalogenation, Enoyl-CoA reduction, and
carbonyl-alcohol oxidoreduction.

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

>gnl|CDD|212496 cd11730, Tthb094_like_SDR_c, Tthb094 and related proteins,
classical (c) SDRs. Tthb094 from Thermus Thermophilus
is a classical SDR which binds NADP. Members of this
subgroup contain the YXXXK active site characteristic of
SDRs. Also, an upstream Asn residue of the canonical
catalytic tetrad is partially conserved in this subgroup
of proteins of undetermined function. SDRs are a
functionally diverse family of oxidoreductases that have
a single domain with a structurally conserved Rossmann
fold (alpha/beta folding pattern with a central
beta-sheet), an NAD(P)(H)-binding region, and a
structurally diverse C-terminal region. Classical SDRs
are typically about 250 residues long, while extended
SDRs are approximately 350 residues. Sequence identity
between different SDR enzymes are typically in the
15-30% range, but the enzymes share the Rossmann fold
NAD-binding motif and characteristic NAD-binding and
catalytic sequence patterns. These enzymes catalyze a
wide range of activities including the metabolism of
steroids, cofactors, carbohydrates, lipids, aromatic
compounds, and amino acids, and act in redox sensing.
Classical SDRs have an TGXXX[AG]XG cofactor binding
motif and a YXXXK active site motif, with the Tyr
residue of the active site motif serving as a critical
catalytic residue (Tyr-151, human prostaglandin
dehydrogenase (PGDH) numbering). In addition to the Tyr
and Lys, there is often an upstream Ser (Ser-138, PGDH
numbering) and/or an Asn (Asn-107, PGDH numbering)
contributing to the active site; while substrate binding
is in the C-terminal region, which determines
specificity. The standard reaction mechanism is a
4-pro-S hydride transfer and proton relay involving the
conserved Tyr and Lys, a water molecule stabilized by
Asn, and nicotinamide. Extended SDRs have additional
elements in the C-terminal region, and typically have a
TGXXGXXG cofactor binding motif. Complex (multidomain)
SDRs such as ketoreductase domains of fatty acid
synthase have a GGXGXXG NAD(P)-binding motif and an
altered active site motif (YXXXN). Fungal type ketoacyl
reductases have a TGXXXGX(1-2)G NAD(P)-binding motif.
Some atypical SDRs have lost catalytic activity and/or
have an unusual NAD(P)-binding motif and missing or
unusual active site residues. Reactions catalyzed within
the SDR family include isomerization, decarboxylation,
epimerization, C=N bond reduction, dehydratase activity,
dehalogenation, Enoyl-CoA reduction, and
carbonyl-alcohol oxidoreduction.

>gnl|CDD|187654 cd08951, DR_C-13_KR_SDR_c_like, daunorubicin C-13 ketoreductase
(KR), classical (c)-like SDRs. Daunorubicin is a
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.

tetrahydromethanopterin dehydrogenase. Methylene
Tetrahydromethanopterin Dehydrogenase (H4MPT DH) NADP
binding domain. NADP-dependent H4MPT DH catalyzes the
dehydrogenation of methylene- H4MPT and
methylene-tetrahydrofolate (H4F) with NADP+ as cofactor.
H4F and H4MPT are both cofactors that carry the
one-carbon units between the formyl and methyl oxidation
level. H4F and H4MPT are structurally analogous to each
other with respect to the pterin moiety, but each has
distinct side chain. H4MPT is present only in anaerobic
methanogenic archaea and aerobic methylotrophic
proteobacteria. H4MPT seems to have evolved
independently from H4F and functions as a distinct
carrier in C1 metabolism. Amino acid DH-like
NAD(P)-binding domains are members of the Rossmann fold
superfamily and include glutamate, leucine, and
phenylalanine DHs, methylene tetrahydrofolate DH,
methylene-tetrahydromethanopterin DH,
methylene-tetrahydropholate DH/cyclohydrolase, Shikimate
DH-like proteins, malate oxidoreductases, and glutamyl
tRNA reductase. Amino acid DHs catalyze the deamination
of amino acids to keto acids with NAD(P)+ as a cofactor.
The NAD(P)-binding Rossmann fold superfamily includes a
wide variety of protein families including NAD(P)-
binding domains of alcohol DHs, tyrosine-dependent
oxidoreductases, glyceraldehyde-3-phosphate DH,
lactate/malate DHs, formate/glycerate DHs, siroheme
synthases, 6-phosphogluconate DH, amino acid DHs,
repressor rex, NAD-binding potassium channel domain,
CoA-binding, and ornithine cyclodeaminase-like domains.
These domains have an alpha-beta-alpha configuration.
NAD binding involves numerous hydrogen and van der Waals
contacts.

>gnl|CDD|187656 cd08953, KR_2_SDR_x, ketoreductase (KR), subgroup 2, complex (x)
SDRs. Ketoreductase, a module of the multidomain
polyketide synthase (PKS), has 2 subdomains, each
corresponding to a SDR family monomer. The C-terminal
subdomain catalyzes the NADPH-dependent reduction of the
beta-carbonyl of a polyketide to a hydroxyl group, a
step in the biosynthesis of polyketides, such as
erythromycin. The N-terminal subdomain, an interdomain
linker, is a truncated Rossmann fold which acts to
stabilizes the catalytic subdomain. Unlike typical SDRs,
the isolated domain does not oligomerize but is composed
of 2 subdomains, each resembling an SDR monomer. The
active site resembles that of typical SDRs, except that
the usual positions of the catalytic Asn and Tyr are
swapped, so that the canonical YXXXK motif changes to
YXXXN. Modular PKSs are multifunctional structures in
which the makeup recapitulates that found in (and may
have evolved from) FAS. Polyketide synthesis also
proceeds via the addition of 2-carbon units as in fatty
acid synthesis. The complex SDR NADP-binding motif,
GGXGXXG, is often present, but is not strictly conserved
in each instance of the module. This subfamily includes
both KR domains of the Bacillus subtilis Pks J,-L, and
PksM, and all three KR domains of PksN, components of
the megacomplex bacillaene synthase, which synthesizes
the antibiotic bacillaene. SDRs are a functionally
diverse family of oxidoreductases that have a single
domain with a structurally conserved Rossmann fold
(alpha/beta folding pattern with a central beta-sheet),
an NAD(P)(H)-binding region, and a structurally diverse
C-terminal region. Classical SDRs are typically about
250 residues long, while extended SDRs are approximately
350 residues. Sequence identity between different SDR
enzymes are typically in the 15-30% range, but the
enzymes share the Rossmann fold NAD-binding motif and
characteristic NAD-binding and catalytic sequence
patterns. These enzymes catalyze a wide range of
activities including the metabolism of steroids,
cofactors, carbohydrates, lipids, aromatic compounds,
and amino acids, and act in redox sensing. Classical
SDRs have an TGXXX[AG]XG cofactor binding motif and a
YXXXK active site motif, with the Tyr residue of the
active site motif serving as a critical catalytic
residue (Tyr-151, human prostaglandin dehydrogenase
(PGDH) numbering). In addition to the Tyr and Lys, there
is often an upstream Ser (Ser-138, PGDH numbering)
and/or an Asn (Asn-107, PGDH numbering) contributing to
the active site; while substrate binding is in the
C-terminal region, which determines specificity. The
standard reaction mechanism is a 4-pro-S hydride
transfer and proton relay involving the conserved Tyr
and Lys, a water molecule stabilized by Asn, and
nicotinamide. Extended SDRs have additional elements in
the C-terminal region, and typically have a TGXXGXXG
cofactor binding motif. Complex (multidomain) SDRs such
as ketoreductase domains of fatty acid synthase have a
GGXGXXG NAD(P)-binding motif and an altered active site
motif (YXXXN). Fungal type KRs have a TGXXXGX(1-2)G
NAD(P)-binding motif. Some atypical SDRs have lost
catalytic activity and/or have an unusual NAD(P)-binding
motif and missing or unusual active site residues.
Reactions catalyzed within the SDR family include
isomerization, decarboxylation, epimerization, C=N bond
reduction, dehydratase activity, dehalogenation,
Enoyl-CoA reduction, and carbonyl-alcohol
oxidoreduction.

>gnl|CDD|187595 cd05334, DHPR_SDR_c_like, dihydropteridine reductase (DHPR),
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
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.

NMRa-like, atypical (a) SDRs. TMR is an atypical
NADP-binding protein of the SDR family. It lacks the
active site residues of the SDRs but has a glycine rich
NAD(P)-binding motif that matches the extended SDRs.
Proteins in this subgroup however, are more similar in
length to the classical SDRs. TMR was identified as a
reducer of triphenylmethane dyes, important
environmental pollutants. This subgroup also includes
Escherichia coli NADPH-dependent quinine oxidoreductase
(QOR2), which catalyzes two-electron reduction of
quinone; but is unlikely to play a major role in
protecting against quinone cytotoxicity. Atypical SDRs
are distinct from classical SDRs. Atypical SDRs include
biliverdin IX beta reductase (BVR-B,aka flavin
reductase), NMRa (a negative transcriptional regulator
of various fungi), progesterone 5-beta-reductase like
proteins, phenylcoumaran benzylic ether and
pinoresinol-lariciresinol reductases, phenylpropene
synthases, eugenol synthase, triphenylmethane reductase,
isoflavone reductases, and others. SDRs are a

Rossmann fold core region typical of all SDRs, extended
SDRs have a less conserved C-terminal extension of
approximately 100 amino acids, and typically have a
TGXXGXXG cofactor binding motif. Complex (multidomain)
SDRs such as ketoreductase domains of fatty acid
synthase have a GGXGXXG NAD(P)-binding motif and an
altered active site motif (YXXXN). Fungal type ketoacyl
reductases have a TGXXXGX(1-2)G NAD(P)-binding motif.

>gnl|CDD|187583 cd05322, SDH_SDR_c_like, Sorbitol 6-phosphate dehydrogenase (SDH),
classical (c) SDRs. Sorbitol 6-phosphate dehydrogenase
(SDH, aka glucitol 6-phosphate dehydrogenase) catalyzes
the NAD-dependent interconversion of D-fructose
6-phosphate to D-sorbitol 6-phosphate. SDH is a member
of the classical SDRs, with the characteristic catalytic
tetrad, but without a complete match to the typical
NAD-binding motif. SDRs are a functionally diverse
family of oxidoreductases that have a single domain with
a structurally conserved Rossmann fold (alpha/beta
folding pattern with a central beta-sheet), an
NAD(P)(H)-binding region, and a structurally diverse
C-terminal region. Classical SDRs are typically about
250 residues long, while extended SDRs are approximately
350 residues. Sequence identity between different SDR
enzymes are typically in the 15-30% range, but the
enzymes share the Rossmann fold NAD-binding motif and
characteristic NAD-binding and catalytic sequence
patterns. These enzymes catalyze a wide range of
activities including the metabolism of steroids,
cofactors, carbohydrates, lipids, aromatic compounds,
and amino acids, and act in redox sensing. Classical
SDRs have an TGXXX[AG]XG cofactor binding motif and a
YXXXK active site motif, with the Tyr residue of the
active site motif serving as a critical catalytic
residue (Tyr-151, human 15-hydroxyprostaglandin
dehydrogenase (15-PGDH) numbering). In addition to the
Tyr and Lys, there is often an upstream Ser (Ser-138,
15-PGDH numbering) and/or an Asn (Asn-107, 15-PGDH
numbering) contributing to the active site; while
substrate binding is in the C-terminal region, which
determines specificity. The standard reaction mechanism
is a 4-pro-S hydride transfer and proton relay involving
the conserved Tyr and Lys, a water molecule stabilized
by Asn, and nicotinamide. Extended SDRs have additional
elements in the C-terminal region, and typically have a
TGXXGXXG cofactor binding motif. Complex (multidomain)
SDRs such as ketoreductase domains of fatty acid
synthase have a GGXGXXG NAD(P)-binding motif and an
altered active site motif (YXXXN). Fungal type ketoacyl
reductases have a TGXXXGX(1-2)G NAD(P)-binding motif.
Some atypical SDRs have lost catalytic activity and/or
have an unusual NAD(P)-binding motif and missing or
unusual active site residues. Reactions catalyzed within
the SDR family include isomerization, decarboxylation,
epimerization, C=N bond reduction, dehydratase activity,
dehalogenation, Enoyl-CoA reduction, and
carbonyl-alcohol oxidoreduction.

>gnl|CDD|187582 cd05274, KR_FAS_SDR_x, ketoreductase (KR) and fatty acid synthase
(FAS), complex (x) SDRs. Ketoreductase, a module of the
multidomain polyketide synthase (PKS), has 2 subdomains,
each corresponding to a SDR family monomer. The
C-terminal subdomain catalyzes the NADPH-dependent
reduction of the beta-carbonyl of a polyketide to a
hydroxyl group, a step in the biosynthesis of
polyketides, such as erythromycin. The N-terminal
subdomain, an interdomain linker, is a truncated
Rossmann fold which acts to stabilizes the catalytic
subdomain. Unlike typical SDRs, the isolated domain does
not oligomerize but is composed of 2 subdomains, each
resembling an SDR monomer. The active site resembles
that of typical SDRs, except that the usual positions of
the catalytic Asn and Tyr are swapped, so that the
canonical YXXXK motif changes to YXXXN. Modular PKSs are
multifunctional structures in which the makeup
recapitulates that found in (and may have evolved from)
FAS. In some instances, such as porcine FAS, an enoyl
reductase (ER) module is inserted between the
sub-domains. Fatty acid synthesis occurs via the
stepwise elongation of a chain (which is attached to
acyl carrier protein, ACP) with 2-carbon units.
Eukaryotic systems consist of large, multifunctional
synthases (type I) while bacterial, type II systems, use
single function proteins. Fungal fatty acid synthase
uses a dodecamer of 6 alpha and 6 beta subunits. In
mammalian type FAS cycles, ketoacyl synthase forms
acetoacetyl-ACP which is reduced by the NADP-dependent
beta-KR, forming beta-hydroxyacyl-ACP, which is in turn
dehydrated by dehydratase to a beta-enoyl intermediate,
which is reduced by NADP-dependent beta-ER. Polyketide
synthesis also proceeds via the addition of 2-carbon
units as in fatty acid synthesis. The complex SDR
NADP-binding motif, GGXGXXG, is often present, but is
not strictly conserved in each instance of the module.
SDRs are a functionally diverse family of
oxidoreductases that have a single domain with a

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

>gnl|CDD|187540 cd05229, SDR_a3, atypical (a) SDRs, subgroup 3. These atypical SDR
family members of unknown function have a glycine-rich
NAD(P)-binding motif consensus that is very similar to
the extended SDRs, GXXGXXG. Generally, this group has
poor conservation of the active site tetrad, However,
individual sequences do contain matches to the YXXXK
active site motif, and generally Tyr or Asn in place of
the upstream Ser found in most SDRs. Atypical SDRs
generally lack the catalytic residues characteristic of
the SDRs, and their glycine-rich NAD(P)-binding motif is
often different from the forms normally seen in
classical or extended SDRs. Atypical SDRs include
biliverdin IX beta reductase (BVR-B,aka flavin
reductase), NMRa (a negative transcriptional regulator
of various fungi), progesterone 5-beta-reductase like
proteins, phenylcoumaran benzylic ether and
pinoresinol-lariciresinol reductases, phenylpropene
synthases, eugenol synthase, triphenylmethane reductase,
isoflavone reductases, and others. SDRs are a
functionally diverse family of oxidoreductases that have
a single domain with a structurally conserved Rossmann
fold, an NAD(P)(H)-binding region, and a structurally
diverse C-terminal region. Sequence identity between
different SDR enzymes is typically in the 15-30% range;
they catalyze a wide range of activities including the
metabolism of steroids, cofactors, carbohydrates,

cofactor binding motif and a YXXXK active site motif,

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.

dehydrogenase. Shikimate dehydrogenase (DH) is an amino
acid DH family member. Shikimate pathway links
metabolism of carbohydrates to de novo biosynthesis of
aromatic amino acids, quinones and folate. It is
essential in plants, bacteria, and fungi but absent in
mammals, thus making enzymes involved in this pathway
ideal targets for broad spectrum antibiotics and
herbicides. Shikimate DH catalyzes the reduction of
3-hydroshikimate to shikimate using the cofactor NADH.
Amino acid DH-like NAD(P)-binding domains are members of
the Rossmann fold superfamily and include glutamate,
leucine, and phenylalanine DHs, methylene
tetrahydrofolate DH, methylene-tetrahydromethanopterin
DH, methylene-tetrahydropholate DH/cyclohydrolase,
Shikimate DH-like proteins, malate oxidoreductases, and
glutamyl tRNA reductase. Amino acid DHs catalyze the
deamination of amino acids to keto acids with NAD(P)+ as
a cofactor. The NAD(P)-binding Rossmann fold superfamily
includes a wide variety of protein families including
NAD(P)- binding domains of alcohol DHs,
tyrosine-dependent oxidoreductases,
glyceraldehyde-3-phosphate DH, lactate/malate DHs,
formate/glycerate DHs, siroheme synthases,
6-phosphogluconate DHs, amino acid DHs, repressor rex,
NAD-binding potassium channel domain, CoA-binding, and
ornithine cyclodeaminase-like domains. These domains
have an alpha-beta-alpha configuration. NAD binding
involves numerous hydrogen and van der Waals contacts.

>gnl|CDD|187645 cd08941, 3KS_SDR_c, 3-keto steroid reductase, classical (c) SDRs.
3-keto steroid reductase (in concert with other enzymes)
catalyzes NADP-dependent sterol C-4 demethylation, as
part of steroid biosynthesis. 3-keto reductase is a
classical SDR, with a well conserved canonical active
site tetrad and fairly well conserved characteristic
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.

SDRs. Ketoreductase, a module of the multidomain
polyketide synthase (PKS), has 2 subdomains, each
corresponding to a SDR family monomer. The C-terminal
subdomain catalyzes the NADPH-dependent reduction of the
beta-carbonyl of a polyketide to a hydroxyl group, a
step in the biosynthesis of polyketides, such as
erythromycin. The N-terminal subdomain, an interdomain
linker, is a truncated Rossmann fold which acts to
stabilizes the catalytic subdomain. Unlike typical SDRs,
the isolated domain does not oligomerize but is composed
of 2 subdomains, each resembling an SDR monomer. The
active site resembles that of typical SDRs, except that
the usual positions of the catalytic Asn and Tyr are
swapped, so that the canonical YXXXK motif changes to
YXXXN. Modular PKSs are multifunctional structures in
which the makeup recapitulates that found in (and may
have evolved from) FAS. Polyketide synthesis also
proceeds via the addition of 2-carbon units as in fatty
acid synthesis. The complex SDR NADP-binding motif,
GGXGXXG, is often present, but is not strictly conserved
in each instance of the module. This subfamily includes
KR domains found in many multidomain PKSs, including six
of seven Sorangium cellulosum PKSs (encoded by
spiDEFGHIJ) which participate in the synthesis of the
polyketide scaffold of the cytotoxic spiroketal
polyketide spirangien. These seven PKSs have either a
single PKS module (SpiF), two PKR modules
(SpiD,-E,-I,-J), or three PKS modules (SpiG,-H). This
subfamily includes the single KR domain of SpiF, the
first KR domains of SpiE,-G,H,-I,and #J, the third KR
domain of SpiG, and the second KR domain of SpiH. The
second KR domains of SpiE,-G, I, and #J, and the KR
domains of SpiD, belong to a different KR_FAS_SDR
subfamily. SDRs are a functionally diverse family of
oxidoreductases that have a single domain with a

(SDRs, aka tyrosine-dependent oxidoreductases) 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

they typically have a TGXXGXXG cofactor binding motif.
Atypical SDRs generally lack the catalytic residues
characteristic of the SDRs, and their glycine-rich

normally seen in classical or extended SDRs. Atypical
SDRs include biliverdin IX beta reductase (BVR-B,aka

of this subfamily are tetrameric NAD-dependent
2-hydroxycarboxylate dehydrogenases including LDHs,
L-2-hydroxyisocaproate dehydrogenases (L-HicDH), and
LDH-like malate dehydrogenases (MDH). Dehydrogenases
catalyze the conversion of carbonyl compounds to
alcohols or amino acids. LDHs catalyze the last step of
glycolysis in which pyruvate is converted to L-lactate.
Vertebrate LDHs are non-allosteric, but some bacterial
LDHs are activated by an allosteric effector such as
fructose-1,6-bisphosphate. L-HicDH catalyzes the
conversion of a variety of 2-oxo carboxylic acids with
medium-sized aliphatic or aromatic side chains. MDH is
one of the key enzymes in the citric acid cycle,
facilitating both the conversion of malate to
oxaloacetate and replenishing levels of oxalacetate by
reductive carboxylation of pyruvate. The LDH-like

>gnl|CDD|187542 cd05231, NmrA_TMR_like_1_SDR_a, NmrA (a transcriptional
regulator) and triphenylmethane reductase (TMR) like
proteins, subgroup 1, atypical (a) SDRs. Atypical SDRs
related to NMRa, TMR, and HSCARG (an NADPH sensor).
This subgroup resembles the SDRs and has a partially
conserved characteristic [ST]GXXGXXG NAD-binding motif,
but lacks the conserved active site residues. NmrA is a
negative transcriptional regulator of various fungi,
involved in the post-translational modulation of the
GATA-type transcription factor AreA. NmrA lacks the
canonical GXXGXXG NAD-binding motif and has altered
residues at the catalytic triad, including a Met
instead of the critical Tyr residue. NmrA may bind
nucleotides but appears to lack any dehydrogenase
activity. HSCARG has been identified as a putative
NADP-sensing molecule, and redistributes and
restructures in response to NADPH/NADP ratios. Like
NmrA, it lacks most of the active site residues of the
SDR family, but has an NAD(P)-binding motif similar to
the extended SDR family, GXXGXXG. 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. Atypical
SDRs are distinct from classical SDRs. Classical SDRs
have an TGXXX[AG]XG cofactor binding motif and a YXXXK
active site motif, with the Tyr residue of the active
site motif serving as a critical catalytic residue
(Tyr-151, human 15-hydroxyprostaglandin dehydrogenase
numbering). In addition to the Tyr and Lys, there is
often an upstream Ser and/or an Asn, contributing to
the active site; while substrate binding is in the
C-terminal region, which determines specificity. The
standard reaction mechanism is a 4-pro-S hydride
transfer and proton relay involving the conserved Tyr
and Lys, a water molecule stabilized by Asn, and
nicotinamide. In addition to the Rossmann fold core
region typical of all SDRs, extended SDRs have a less
conserved C-terminal extension of approximately 100
amino acids, and typically have a TGXXGXXG cofactor
binding motif. Complex (multidomain) SDRs such as
ketoreductase domains of fatty acid synthase have a
GGXGXXG NAD(P)-binding motif and an altered active site
motif (YXXXN). Fungal type ketoacyl reductases have a
TGXXXGX(1-2)G NAD(P)-binding motif.

>gnl|CDD|133452 cd05213, NAD_bind_Glutamyl_tRNA_reduct, NADP-binding domain of
glutamyl-tRNA reductase. Glutamyl-tRNA reductase
catalyzes the conversion of glutamyl-tRNA to
glutamate-1-semialdehyde, initiating the synthesis of
tetrapyrrole. Whereas tRNAs are generally associated
with peptide bond formation in protein translation, here
the tRNA activates glutamate in the initiation of
tetrapyrrole biosynthesis in archaea, plants and many
bacteria. In the first step, activated glutamate is
reduced to glutamate-1-semi-aldehyde via the NADPH
dependent glutamyl-tRNA reductase. Glutamyl-tRNA
reductase forms a V-shaped dimer. Each monomer has 3
domains: an N-terminal catalytic domain, a classic
nucleotide binding domain, and a C-terminal dimerization
domain. Although the representative structure 1GPJ lacks
a bound NADPH, a theoretical binding pocket has been
described. (PMID 11172694). Amino acid dehydrogenase
(DH)-like NAD(P)-binding domains are members of the
Rossmann fold superfamily and include glutamate,
leucine, and phenylalanine DHs, methylene
tetrahydrofolate DH, methylene-tetrahydromethanopterin
DH, methylene-tetrahydropholate DH/cyclohydrolase,
Shikimate DH-like proteins, malate oxidoreductases, and
glutamyl tRNA reductase. Amino acid DHs catalyze the
deamination of amino acids to keto acids with NAD(P)+ as
a cofactor. The NAD(P)-binding Rossmann fold superfamily
includes a wide variety of protein families including
NAD(P)- binding domains of alcohol DHs,
tyrosine-dependent oxidoreductases,
glyceraldehyde-3-phosphate DH, lactate/malate DHs,
formate/glycerate DHs, siroheme synthases,
6-phosphogluconate DH, amino acid DHs, repressor rex,
NAD-binding potassium channel domain, CoA-binding, and
ornithine cyclodeaminase-like domains. These domains
have an alpha-beta-alpha configuration. NAD binding
involves numerous hydrogen and van der Waals contacts.

>gnl|CDD|187554 cd05243, SDR_a5, atypical (a) SDRs, subgroup 5. This subgroup
contains atypical SDRs, some of which are identified as
putative NAD(P)-dependent epimerases, one as a putative
NAD-dependent epimerase/dehydratase. Atypical SDRs are
distinct from classical SDRs. Members of this subgroup
have a glycine-rich NAD(P)-binding motif that is very
similar to the extended SDRs, GXXGXXG, and binds NADP.
Generally, this subgroup has poor conservation of the
active site tetrad; however, individual sequences do
contain matches to the YXXXK active site motif, the
upstream Ser, and there is a highly conserved Asp in
place of the usual active site Asn throughout the
subgroup. Atypical SDRs generally lack the catalytic
residues characteristic of the SDRs, and their
glycine-rich NAD(P)-binding motif is often different
from the forms normally seen in classical or extended
SDRs. Atypical SDRs include biliverdin IX beta
reductase (BVR-B,aka flavin reductase), NMRa (a
negative transcriptional regulator of various fungi),
progesterone 5-beta-reductase like proteins,
phenylcoumaran benzylic ether and
pinoresinol-lariciresinol reductases, phenylpropene

contains one P-cluster (at the alphabeta interface) and,
one molecule of iron molybdenum cofactor (FeMoco)

>gnl|CDD|187543 cd05232, UDP_G4E_4_SDR_e, UDP-glucose 4 epimerase, subgroup 4,
extended (e) SDRs. UDP-glucose 4 epimerase (aka
UDP-galactose-4-epimerase), is a homodimeric extended
SDR. It catalyzes the NAD-dependent conversion of
UDP-galactose to UDP-glucose, the final step in Leloir
galactose synthesis. This subgroup is comprised of
bacterial proteins, and includes the Staphylococcus
aureus capsular polysaccharide Cap5N, which may have a
role in the synthesis of UDP-N-acetyl-d-fucosamine. This
subgroup has the characteristic active site tetrad and
NAD-binding motif of the extended SDRs. 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.

catalyzes a first step in the biosynthesis from Asp of
Lys (and its precursor diaminopimelate), Met, and Thr.
In E. coli, a distinct isozyme is inhibited by each of
the three amino acid products. The Met-sensitive (I) and
Thr-sensitive (II) forms are bifunctional enzymes fused
to homoserine dehydrogenases and form homotetramers,
while the Lys-sensitive form (III) is a monofunctional
homodimer.The Lys-sensitive enzyme of Bacillus subtilis
resembles the E. coli form but is an alpha 2/beta 2
heterotetramer, where the beta subunit is translated
from an in-phase alternative initiator at Met-246. This
may be a feature of a number of closely related forms,
including a paralog from B. subtilis [Amino acid
