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.

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

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

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

motif and missing or unusual active site residues.
Reactions catalyzed within the SDR family include
isomerization, decarboxylation, epimerization, C=N bond
reduction, dehydratase activity, dehalogenation,
Enoyl-CoA reduction, and carbonyl-alcohol
oxidoreduction. A critical catalytic Tyr residue
(Tyr-151, human 15-hydroxyprostaglandin dehydrogenase
(15-PGDH) numbering), is often found in a conserved
YXXXK pattern. In addition to the Tyr and Lys, there is
often an upstream Ser (Ser-138, 15-PGDH numbering)
and/or an Asn (Asn-107, 15-PGDH numbering) or additional
Ser, contributing to the active site. Substrates for
these enzymes include sugars, steroids, alcohols, and
aromatic compounds. The standard reaction mechanism is a
proton relay involving the conserved Tyr-151 and
Lys-155, and well as Asn-111 (or Ser). Some SDR family
members, including 17 beta-hydroxysteroid dehydrogenase
contain an additional helix-turn-helix motif that is not
generally found among SDRs.

>gnl|CDD|187624 cd05366, meso-BDH-like_SDR_c, meso-2,3-butanediol
dehydrogenase-like, classical (c) SDRs. 2,3-butanediol
dehydrogenases (BDHs) catalyze the NAD+ dependent
conversion of 2,3-butanediol to acetonin; BDHs are
classified into types according to their
stereospecificity as to substrates and products.
Included in this subgroup are Klebsiella pneumonia
meso-BDH which catalyzes meso-2,3-butanediol to
D(-)-acetonin, and Corynebacterium glutamicum L-BDH
which catalyzes lX+)-2,3-butanediol to L(+)-acetonin.
This subgroup is comprised of classical SDRs with the
characteristic catalytic triad and NAD-binding motif.
SDRs are a functionally diverse family of
oxidoreductases that have a single domain with a
structurally conserved Rossmann fold (alpha/beta folding
pattern with a central beta-sheet), an NAD(P)(H)-binding
region, and a structurally diverse C-terminal region.
Classical SDRs are typically about 250 residues long,
while extended SDRs are approximately 350 residues.
Sequence identity between different SDR enzymes are
typically in the 15-30% range, but the enzymes share the
Rossmann fold NAD-binding motif and characteristic
NAD-binding and catalytic sequence patterns. These
enzymes catalyze a wide range of activities including
the metabolism of steroids, cofactors, carbohydrates,
lipids, aromatic compounds, and amino acids, and act in
redox sensing. Classical SDRs have an TGXXX[AG]XG
cofactor binding motif and a YXXXK active site motif,
with the Tyr residue of the active site motif serving as
a critical catalytic residue (Tyr-151, human
15-hydroxyprostaglandin dehydrogenase (15-PGDH)
numbering). In addition to the Tyr and Lys, there is
often an upstream Ser (Ser-138, 15-PGDH numbering)
and/or an Asn (Asn-107, 15-PGDH numbering) contributing
to the active site; while substrate binding is in the
C-terminal region, which determines specificity. The
standard reaction mechanism is a 4-pro-S hydride
transfer and proton relay involving the conserved Tyr
and Lys, a water molecule stabilized by Asn, and
nicotinamide. Extended SDRs have additional elements in
the C-terminal region, and typically have a TGXXGXXG
cofactor binding motif. Complex (multidomain) SDRs such
as ketoreductase domains of fatty acid synthase have a
GGXGXXG NAD(P)-binding motif and an altered active site
motif (YXXXN). Fungal type ketoacyl reductases have a
TGXXXGX(1-2)G NAD(P)-binding motif. Some atypical SDRs
have lost catalytic activity and/or have an unusual
NAD(P)-binding motif and missing or unusual active site
residues. Reactions catalyzed within the SDR family
include isomerization, decarboxylation, epimerization,
C=N bond reduction, dehydratase activity,
dehalogenation, Enoyl-CoA reduction, and
carbonyl-alcohol oxidoreduction.

>gnl|CDD|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.

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

[ACP] reductase (BKR), subgroup 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.

and related proteins, classical (c) SDR. These proteins
include members identified as KDSR, ribitol type
dehydrogenase, and others. The group shows strong
conservation of the active site tetrad and glycine rich
NAD-binding motif of the classical SDRs. SDRs are a
functionally diverse family of oxidoreductases that have
a single domain with a structurally conserved Rossmann
fold (alpha/beta folding pattern with a central
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|187647 cd08943, R1PA_ADH_SDR_c, rhamnulose-1-phosphate aldolase/alcohol
dehydrogenase, classical (c) SDRs. This family has
bifunctional proteins with an N-terminal aldolase and a
C-terminal classical SDR domain. One member is
identified as a rhamnulose-1-phosphate aldolase/alcohol
dehydrogenase. The SDR domain has a canonical SDR
glycine-rich NAD(P) binding motif and a match to the
characteristic active site triad. However, it lacks an
upstream active site Asn typical of SDRs. SDRs are a
functionally diverse family of oxidoreductases that have
a single domain with a structurally conserved Rossmann
fold (alpha/beta folding pattern with a central
beta-sheet), an NAD(P)(H)-binding region, and a
structurally diverse C-terminal region. Classical SDRs
are typically about 250 residues long, while extended
SDRs are approximately 350 residues. Sequence identity
between different SDR enzymes are typically in the
15-30% range, but the enzymes share the Rossmann fold
NAD-binding motif and characteristic NAD-binding and
catalytic sequence patterns. These enzymes catalyze a
wide range of activities including the metabolism of
steroids, cofactors, carbohydrates, lipids, aromatic
compounds, and amino acids, and act in redox sensing.
Classical SDRs have an TGXXX[AG]XG cofactor binding
motif and a YXXXK active site motif, with the Tyr
residue of the active site motif serving as a critical
catalytic residue (Tyr-151, human
15-hydroxyprostaglandin dehydrogenase (15-PGDH)
numbering). In addition to the Tyr and Lys, there is
often an upstream Ser (Ser-138, 15-PGDH numbering)
and/or an Asn (Asn-107, 15-PGDH numbering) contributing
to the active site; while substrate binding is in the
C-terminal region, which determines specificity. The
standard reaction mechanism is a 4-pro-S hydride
transfer and proton relay involving the conserved Tyr
and Lys, a water molecule stabilized by Asn, and
nicotinamide. Extended SDRs have additional elements in
the C-terminal region, and typically have a TGXXGXXG
cofactor binding motif. Complex (multidomain) SDRs such
as ketoreductase domains of fatty acid synthase have a
GGXGXXG NAD(P)-binding motif and an altered active site
motif (YXXXN). Fungal type ketoacyl reductases have a
TGXXXGX(1-2)G NAD(P)-binding motif. Some atypical SDRs
have lost catalytic activity and/or have an unusual
NAD(P)-binding motif and missing or unusual active site
residues. Reactions catalyzed within the SDR family
include isomerization, decarboxylation, epimerization,
C=N bond reduction, dehydratase activity,
dehalogenation, Enoyl-CoA reduction, and
carbonyl-alcohol oxidoreduction.

>gnl|CDD|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|187602 cd05344, BKR_like_SDR_like, putative beta-ketoacyl acyl carrier
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.

SDRs. This subgroup includes human DHRS1 and human
HSDL2 and related proteins. These are members of the
classical SDR family, with a canonical Gly-rich
NAD-binding motif and the typical YXXXK active site
motif. However, the rest of the catalytic tetrad is not
strongly conserved. DHRS1 mRNA has been detected in many

pancreas; a longer transcript is predominantly expressed
in the liver , a shorter one in the heart. HSDL2 may
play a part in fatty acid metabolism, as it is found in

standard reaction mechanism is a 4-pro-S hydride

nicotinamide. Extended SDRs have additional elements in
the C-terminal region, and typically have a TGXXGXXG

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

TGXXXGX(1-2)G NAD(P)-binding motif. 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|187636 cd08931, SDR_c9, classical (c) SDR, subgroup 9. This subgroup has
the canonical active site tetrad and NAD-binding motif
of the classical SDRs. SDRs are a functionally diverse
family of oxidoreductases that have a single domain with
a structurally conserved Rossmann fold (alpha/beta
folding pattern with a central beta-sheet), an
NAD(P)(H)-binding region, and a structurally diverse
C-terminal region. Classical SDRs are typically about
250 residues long, while extended SDRs are approximately
350 residues. Sequence identity between different SDR
enzymes are typically in the 15-30% range, but the
enzymes share the Rossmann fold NAD-binding motif and
characteristic NAD-binding and catalytic sequence
patterns. These enzymes catalyze a wide range of
activities including the metabolism of steroids,
cofactors, carbohydrates, lipids, aromatic compounds,
and amino acids, and act in redox sensing. Classical
SDRs have an TGXXX[AG]XG cofactor binding motif and a
YXXXK active site motif, with the Tyr residue of the
active site motif serving as a critical catalytic
residue (Tyr-151, human 15-hydroxyprostaglandin
dehydrogenase (15-PGDH) numbering). In addition to the
Tyr and Lys, there is often an upstream Ser (Ser-138,
15-PGDH numbering) and/or an Asn (Asn-107, 15-PGDH
numbering) contributing to the active site; while
substrate binding is in the C-terminal region, which
determines specificity. The standard reaction mechanism
is a 4-pro-S hydride transfer and proton relay involving
the conserved Tyr and Lys, a water molecule stabilized
by Asn, and nicotinamide. Extended SDRs have additional
elements in the C-terminal region, and typically have a
TGXXGXXG cofactor binding motif. Complex (multidomain)
SDRs such as ketoreductase domains of fatty acid
synthase have a GGXGXXG NAD(P)-binding motif and an
altered active site motif (YXXXN). Fungal type ketoacyl
reductases have a TGXXXGX(1-2)G NAD(P)-binding motif.
Some atypical SDRs have lost catalytic activity and/or
have an unusual NAD(P)-binding motif and missing or
unusual active site residues. Reactions catalyzed within
the SDR family include isomerization, decarboxylation,
epimerization, C=N bond reduction, dehydratase activity,
dehalogenation, Enoyl-CoA reduction, and
carbonyl-alcohol oxidoreduction.

>gnl|CDD|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.

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

>gnl|CDD|187635 cd08930, SDR_c8, classical (c) SDR, subgroup 8. This subgroup has
a fairly well conserved active site tetrad and domain
size of the classical SDRs, but has an atypical
NAD-binding motif ([ST]G[GA]XGXXG). SDRs are a
functionally diverse family of oxidoreductases that have
a single domain with a structurally conserved Rossmann
fold (alpha/beta folding pattern with a central
beta-sheet), an NAD(P)(H)-binding region, and a
structurally diverse C-terminal region. Classical SDRs
are typically about 250 residues long, while extended
SDRs are approximately 350 residues. Sequence identity
between different SDR enzymes are typically in the
15-30% range, but the enzymes share the Rossmann fold
NAD-binding motif and characteristic NAD-binding and
catalytic sequence patterns. These enzymes catalyze a
wide range of activities including the metabolism of
steroids, cofactors, carbohydrates, lipids, aromatic
compounds, and amino acids, and act in redox sensing.
Classical SDRs have an TGXXX[AG]XG cofactor binding
motif and a YXXXK active site motif, with the Tyr
residue of the active site motif serving as a critical
catalytic residue (Tyr-151, human
15-hydroxyprostaglandin dehydrogenase (15-PGDH)
numbering). In addition to the Tyr and Lys, there is
often an upstream Ser (Ser-138, 15-PGDH numbering)
and/or an Asn (Asn-107, 15-PGDH numbering) contributing
to the active site; while substrate binding is in the
C-terminal region, which determines specificity. The
standard reaction mechanism is a 4-pro-S hydride
transfer and proton relay involving the conserved Tyr
and Lys, a water molecule stabilized by Asn, and
nicotinamide. Extended SDRs have additional elements in
the C-terminal region, and typically have a TGXXGXXG
cofactor binding motif. Complex (multidomain) SDRs such
as ketoreductase domains of fatty acid synthase have a
GGXGXXG NAD(P)-binding motif and an altered active site
motif (YXXXN). Fungal type ketoacyl reductases have a
TGXXXGX(1-2)G NAD(P)-binding motif. Some atypical SDRs
have lost catalytic activity and/or have an unusual
NAD(P)-binding motif and missing or unusual active site
residues. Reactions catalyzed within the SDR family
include isomerization, decarboxylation, epimerization,
C=N bond reduction, dehydratase activity,
dehalogenation, Enoyl-CoA reduction, and
carbonyl-alcohol oxidoreduction.

[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

>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.

of proteins of undetermined function. SDRs are a
functionally diverse family of oxidoreductases that have

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,

SDRs. Escherichia coli K-12 YCIK and related proteins
have a canonical classical SDR nucleotide-binding motif
and active site tetrad. They are predicted oxoacyl-(acyl
carrier protein/ACP) reductases. 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.

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

TTER is a peroxisomal protein with a proposed role in
fatty acid elongation. Fatty acid synthesis is known to
occur in the both endoplasmic reticulum and
mitochondria; peroxisomal TER has been proposed as an
additional fatty acid elongation system, it reduces the
double bond at C-2 as the last step of elongation. This
system resembles the mitochondrial system in that
acetyl-CoA is used as a carbon donor. TER may also
function in phytol metabolism, reducting phytenoyl-CoA
to phytanoyl-CoA in peroxisomes. DECR processes double
bonds in fatty acids to increase their utility in fatty
acid metabolism; it reduces 2,4-dienoyl-CoA to an
enoyl-CoA. DECR is active in mitochondria and
peroxisomes. This subgroup has the Gly-rich NAD-binding
motif of the classical SDR family, but does not display
strong identity to the canonical active site tetrad, and
lacks the characteristic Tyr at the usual position. SDRs
are a functionally diverse family of oxidoreductases
that have a single domain with a structurally conserved
Rossmann fold (alpha/beta folding pattern with a central

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

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

[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.

These are members of the classical SDR family, with a
canonical Gly-rich NAD-binding motif and the typical
YXXXK active site motif. However, the rest of the
catalytic tetrad is not strongly conserved. DHRS1 mRNA
has been detected in many tissues, liver, heart,
skeletal muscle, kidney and pancreas; a longer
transcript is predominantly expressed in the liver , a
shorter one in the heart. SDRs are a functionally
diverse family of oxidoreductases that have a single
domain with a structurally conserved Rossmann fold
(alpha/beta folding pattern with a central beta-sheet),
an NAD(P)(H)-binding region, and a structurally diverse
C-terminal region. Classical SDRs are typically about
250 residues long, while extended SDRS are approximately
350 residues. Sequence identity between different SDR
enzymes are typically in the 15-30% range, but the
enzymes share the Rossmann fold NAD-binding motif and
characteristic NAD-binding and catalytic sequence
patterns. These enzymes have a 3-glycine N-terminal
NAD(P)(H)-binding pattern (typically, TGxxxGxG in
classical SDRs and TGxxGxxG in extended SDRs), while
substrate binding is in the C-terminal region. A
critical catalytic Tyr residue (Tyr-151, human
15-hydroxyprostaglandin dehydrogenase (15-PGDH)

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.

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

erythromycin. The N-terminal subdomain, an interdomain
linker, is a truncated Rossmann fold which acts to

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|200572 cd10948, CE4_BsPdaA_like, Catalytic NodB homology domain of
Bacillus subtilis polysaccharide deacetylase PdaA, and
its bacterial homologs. The Bacillus subtilis genome
contains six polysaccharide deacetylase gene homologs:
pdaA, pdaB (previously known as ybaN), yheN, yjeA, yxkH
and ylxY. This family is represented by Bacillus
subtilis pdaA gene encoding polysaccharide deacetylase
BsPdaA, which is a member of the carbohydrate esterase
4 (CE4) superfamily. BsPdaA deacetylates peptidoglycan
N-acetylmuramic acid (MurNAc) residues to facilitate
the formation of muramic delta-lactam, which is
required for recognition of germination lytic enzymes.
BsPdaA deficiency leads to the absence of muramic
delta-lactam residues in the spore cortex. Like other
CE4 esterases, BsPdaA consists of a single catalytic
NodB homology domain that appears to adopt a deformed
(beta/alpha)8 barrel fold with a putative substrate
binding groove harboring the majority of the conserved
residues. It utilizes a general acid/base catalytic
mechanism involving a tetrahedral transition
intermediate, where a water molecule functions as the
nucleophile tightly associated to the zinc cofactor.
