>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.

C-terminal domain of fatty acyl CoA reductases, a family
of SDR-like proteins. SDRs or short-chain
dehydrogenases/reductases are Rossmann-fold
NAD(P)H-binding proteins. Many proteins in this FAR_C
family may function as fatty acyl-CoA reductases (FARs),
acting on medium and long chain fatty acids, and have

extended (e) SDRs. This subgroup of extended SDR family
domains have the characteristic active site tetrad and a
well-conserved NAD(P)-binding motif. This subgroup is
not well characterized, its members are annotated as

>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.

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

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

dehydrogenase-like protein)-like, extended (e) SDRs.
This subgroup includes human NSDHL and related proteins.
These proteins have the characteristic active site
tetrad of extended SDRs, and also have a close match to
their NAD(P)-binding motif. Human NSDHL is a
3beta-hydroxysteroid dehydrogenase (3 beta-HSD) which
functions in the cholesterol biosynthetic pathway. 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.
Mutations in the gene encoding NSDHL cause CHILD
syndrome (congenital hemidysplasia with ichthyosiform
nevus and limb defects), an X-linked dominant,
male-lethal trait. This subgroup also includes an
unusual bifunctional [3beta-hydroxysteroid dehydrogenase
(3b-HSD)/C-4 decarboxylase from Arabidopsis thaliana,
and Saccharomyces cerevisiae ERG26, a 3b-HSD/C-4
decarboxylase, involved in the synthesis of ergosterol,
the major sterol of yeast. 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

>gnl|CDD|187564 cd05254, dTDP_HR_like_SDR_e, dTDP-6-deoxy-L-lyxo-4-hexulose
reductase and related proteins, extended (e) SDRs.
dTDP-6-deoxy-L-lyxo-4-hexulose reductase, an extended
SDR, synthesizes dTDP-L-rhamnose from
alpha-D-glucose-1-phosphate, providing the precursor of
L-rhamnose, an essential cell wall component of many
pathogenic bacteria. This subgroup has the
characteristic active site tetrad and NADP-binding
motif. This subgroup also contains human MAT2B, the
regulatory subunit of methionine adenosyltransferase
(MAT); MAT catalyzes S-adenosylmethionine synthesis. The
human gene encoding MAT2B encodes two major splicing
variants which are induced in human cell liver cancer
and regulate HuR, an mRNA-binding protein which
stabilizes the mRNA of several cyclins, to affect cell
proliferation. Both MAT2B variants include this extended
SDR domain. Extended SDRs are distinct from classical
SDRs. In addition to the Rossmann fold (alpha/beta
folding pattern with a central beta-sheet) core region
typical of all SDRs, extended SDRs have a less conserved
C-terminal extension of approximately 100 amino acids.
Extended SDRs are a diverse collection 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.

3, extended (e) SDRs. Members of this bacterial
subgroup are identified as possible sugar epimerases,
such as UDP-glucose 4 epimerase. However, while the
NAD(P)-binding motif is fairly well conserved, not all
members retain the canonical active site tetrad of the
extended 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. Extended SDRs are distinct from
classical SDRs. In addition to the Rossmann fold

extended (e) SDRs. This subgroup contains proteins of
unknown function related to aldehyde reductase and
flavonoid reductase of the extended SDR-type. Aldehyde
reductase I (aka carbonyl reductase) is an NADP-binding
SDR; it has an NADP-binding motif consensus that is
slightly different from the canonical SDR form and lacks
the Asn of the extended SDR active site tetrad. Aldehyde
reductase I catalyzes the NADP-dependent reduction of
ethyl 4-chloro-3-oxobutanoate to ethyl
(R)-4-chloro-3-hydroxybutanoate. The related flavonoid
reductases act in the NADP-dependent reduction of
flavonoids, ketone-containing plant secondary
metabolites. Extended SDRs are distinct from classical
SDRs. In addition to the Rossmann fold (alpha/beta
