>gnl|CDD|187547 cd05236, FAR-N_SDR_e, fatty acyl CoA reductases (FARs), extended
(e) SDRs. SDRs are Rossmann-fold NAD(P)H-binding
proteins, many of which may function as fatty acyl CoA
reductases (FAR), acting on medium and long chain fatty
acids, and have been reported to be involved in diverse
processes such as biosynthesis of insect pheromones,
plant cuticular wax production, and mammalian wax
biosynthesis. In Arabidopsis thaliana, proteins with
this particular architecture have also been identified
as the MALE STERILITY 2 (MS2) gene product, which is
implicated in male gametogenesis. Mutations in MS2
inhibit the synthesis of exine (sporopollenin),
rendering plants unable to reduce pollen wall fatty
acids to corresponding alcohols. This N-terminal domain
shares the catalytic triad (but not the upstream Asn)
and characteristic NADP-binding motif of the extended
SDR family. 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.

>gnl|CDD|187546 cd05235, SDR_e1, extended (e) SDRs, subgroup 1. This family
consists of an SDR module of multidomain proteins
identified as putative polyketide sythases fatty acid
synthases (FAS), and nonribosomal peptide synthases,

>gnl|CDD|233557 TIGR01746, Thioester-redct, thioester reductase domain. This model
includes the terminal domain from the fungal alpha
aminoadipate reductase enzyme (also known as
aminoadipate semialdehyde dehydrogenase) which is
involved in the biosynthesis of lysine , as well as the
reductase-containing component of the myxochelin
biosynthetic gene cluster, MxcG. The mechanism of
reduction involves activation of the substrate by
adenylation and transfer to a covalently-linked
pantetheine cofactor as a thioester. This thioester is
then reduced to give an aldehyde (thus releasing the
product) and a regenerated pantetheine thiol. (In
myxochelin biosynthesis this aldehyde is further reduced
to an alcohol or converted to an amine by an
aminotransferase.) This is a fundamentally different
reaction than beta-ketoreductase domains of polyketide
synthases which act at a carbonyl two carbons removed
from the thioester and forms an alcohol as a product.
This domain is invariably found at the C-terminus of the
proteins which contain it (presumably because it results
in the release of the product). The majority of hits to
this model are non-ribosomal peptide synthetases in
which this domain is similarly located proximal to a
thiolation domain (pfam00550). In some cases this domain
is found at the end of a polyketide synthetase enzyme,
but is unlike ketoreductase domains which are found
before the thiolase domains. Exceptions to this observed
relationship with the thiolase domain include three
proteins which consist of stand-alone reductase domains
(GP|466833 from M. leprae, GP|435954 from Anabaena and
OMNI|NTL02SC1199 from Strep. coelicolor) and one protein
(OMNI|NTL01NS2636 from Nostoc) which contains N-terminal
homology with a small group of hypothetical proteins but
no evidence of a thiolation domain next to the putative
reductase domain. Below the noise cutoff to this model
are proteins containing more distantly related
ketoreductase and dehydratase/epimerase domains. It has
been suggested that a NADP-binding motif can be found in
the N-terminal portion of this domain that may form a
Rossman-type fold.

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

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

dehydrogenase) and HSD3B1(delta 5-delta
4-isomerase)-like, extended (e) SDRs. This extended-SDR
subgroup includes human 3 beta-HSD/HSD3B1 and C(27)
3beta-HSD/ [3beta-hydroxy-delta(5)-C(27)-steroid
oxidoreductase; HSD3B7], and related proteins. These
proteins have the characteristic active site tetrad and
NAD(P)-binding motif of extended SDRs. 3 beta-HSD
catalyzes the oxidative conversion of delta 5-3
beta-hydroxysteroids to the delta 4-3-keto
configuration; this activity is essential for the
biosynthesis of all classes of hormonal steroids. C(27)
3beta-HSD is a membrane-bound enzyme of the endoplasmic
reticulum, it catalyzes the isomerization and oxidation
of 7alpha-hydroxylated sterol intermediates, an early
step in bile acid biosynthesis. Mutations in the human
gene encoding C(27) 3beta-HSD underlie a rare autosomal
recessive form of neonatal cholestasis. 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 sythase 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.

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.

extended (e) SDRs. This subgroup contains
UDP-N-acetylglucosamine 4-epimerase of Pseudomonas
aeruginosa, WbpP, an extended SDR, that catalyzes the
NAD+ dependent conversion of UDP-GlcNAc and UDPGalNA to
UDP-Glc and UDP-Gal. 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

this subgroup are poorly defined and have been
identified putatively as isoflavones reductase, sugar
