>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.
