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

>gnl|CDD|187631 cd05373, SDR_c10, classical (c) SDR, subgroup 10. This subgroup
resembles the classical SDRs, but has an incomplete
match to the canonical glycine rich NAD-binding motif
and lacks the typical active site tetrad (instead of
the critical active site Tyr, it has Phe, but contains
the nearby Lys). SDRs are a functionally diverse family
of oxidoreductases that have a single domain with a
structurally conserved Rossmann fold (alpha/beta
folding pattern with a central beta-sheet), an
NAD(P)(H)-binding region, and a structurally diverse
C-terminal region. Classical SDRs are typically about
250 residues long, while extended SDRs are
approximately 350 residues. Sequence identity between
different SDR enzymes are typically in the 15-30%
range, but the enzymes share the Rossmann fold
NAD-binding motif and characteristic NAD-binding and
catalytic sequence patterns. These enzymes catalyze a
wide range of activities including the metabolism of
steroids, cofactors, carbohydrates, lipids, aromatic
compounds, and amino acids, and act in redox sensing.
Classical SDRs have an TGXXX[AG]XG cofactor binding
motif and a YXXXK active site motif, with the Tyr
residue of the active site motif serving as a critical
catalytic residue (Tyr-151, human
15-hydroxyprostaglandin dehydrogenase (15-PGDH)
numbering). In addition to the Tyr and Lys, there is
often an upstream Ser (Ser-138, 15-PGDH numbering)
and/or an Asn (Asn-107, 15-PGDH numbering) contributing
to the active site; while substrate binding is in the
C-terminal region, which determines specificity. The
standard reaction mechanism is a 4-pro-S hydride
transfer and proton relay involving the conserved Tyr
and Lys, a water molecule stabilized by Asn, and
nicotinamide. Extended SDRs have additional elements in
the C-terminal region, and typically have a TGXXGXXG
cofactor binding motif. Complex (multidomain) SDRs such
as ketoreductase domains of fatty acid synthase have a
GGXGXXG NAD(P)-binding motif and an altered active site
motif (YXXXN). Fungal type ketoacyl reductases have a
TGXXXGX(1-2)G NAD(P)-binding motif. Some atypical SDRs
have lost catalytic activity and/or have an unusual
NAD(P)-binding motif and missing or unusual active site
residues. Reactions catalyzed within the SDR family
include isomerization, decarboxylation, epimerization,
C=N bond reduction, dehydratase activity,
dehalogenation, Enoyl-CoA reduction, and
carbonyl-alcohol oxidoreduction.

>gnl|CDD|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

aromatic compounds. The standard reaction mechanism is
a proton relay involving the conserved Tyr-151 and

>gnl|CDD|187627 cd05369, TER_DECR_SDR_a, Trans-2-enoyl-CoA reductase (TER) and
2,4-dienoyl-CoA reductase (DECR), atypical (a) SDR.
TTER is a peroxisomal protein with a proposed role in
fatty acid elongation. Fatty acid synthesis is known to
occur in the both endoplasmic reticulum and
mitochondria; peroxisomal TER has been proposed as an
additional fatty acid elongation system, it reduces the
double bond at C-2 as the last step of elongation.
This system resembles the mitochondrial system in that
acetyl-CoA is used as a carbon donor. TER may also
function in phytol metabolism, reducting phytenoyl-CoA
to phytanoyl-CoA in peroxisomes. DECR processes double
bonds in fatty acids to increase their utility in fatty
acid metabolism; it reduces 2,4-dienoyl-CoA to an
enoyl-CoA. DECR is active in mitochondria and
peroxisomes. This subgroup has the Gly-rich NAD-binding
motif of the classical SDR family, but does not display
strong identity to the canonical active site tetrad,
and lacks the characteristic Tyr at the usual position.

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

have been isolated. In higher plants, the growth
regulator indole-3-acetic acid (IAA or auxin) is found
both free and conjugated via amide bonding to a variety
of amino acids and peptides, and via an ester linkage to
carbohydrates. IAA-Asp conjugates are involved in
homeostatic control, protection, storing and subsequent
use of free IAA. IAA-Asp is also found in some plants as
a unique intermediate for entering into IAA
non-decarboxylative oxidative pathway. IAA
amidohydrolase cleaves the amide bond between the auxin
and the conjugated amino acid. Enterobacter agglomerans

specificity towards IAA-Asp, although its substrate
affinity is weaker compared to Arabidopsis enzymes of

>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.

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.
