>gnl|CDD|212495 cd09807, retinol-DH_like_SDR_c, retinol dehydrogenases
(retinol-DHs), classical (c) SDRs. Classical SDR-like
subgroup containing retinol-DHs and related proteins.
Retinol is processed by a medium chain alcohol
dehydrogenase followed by retinol-DHs. Proteins in this
subfamily share the glycine-rich NAD-binding motif of
the classical SDRs, have a partial match to the
canonical active site tetrad, but lack the typical
active site Ser. This subgroup includes the human
proteins: retinol dehydrogenase -12, -13 ,and -14. 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.

(retinol-DH), Light dependent Protochlorophyllide
(Pchlide) OxidoReductase (LPOR) and related proteins,
classical (c) SDRs. Classical SDR subgroup containing
retinol-DHs, LPORs, and related proteins. Retinol is
processed by a medium chain alcohol dehydrogenase
followed by retinol-DHs. Pchlide reductases act in
chlorophyll biosynthesis. There are distinct enzymes
that catalyze Pchlide reduction in light or dark
conditions. Light-dependent reduction is via an
NADP-dependent SDR, LPOR. Proteins in this subfamily
share the glycine-rich NAD-binding motif of the
classical SDRs, have a partial match to the canonical
active site tetrad, but lack the typical active site
Ser. This subgroup includes the human proteins: retinol
dehydrogenase -12, -13 ,and -14, dehydrogenase/reductase
SDR family member (DHRS)-12 , -13 and -X (a DHRS on
chromosome X), and WWOX (WW domain-containing
oxidoreductase), as well as a Neurospora crassa SDR
encoded by the blue light inducible bli-4 gene. SDRs are

reductase (PTCR)-like, classical (c) SDRs. PTCR is a
classical SDR which catalyzes the NADPH-dependent
reduction of ketones on steroids and prostaglandins.
Unlike most SDRs, PTCR functions as a monomer. This
subgroup also includes human carbonyl reductase 1 (CBR1)
and CBR3. CBR1 is an NADPH-dependent SDR with broad
substrate specificity and may be responsible for the in
vivo reduction of quinones, prostaglandins, and other
carbonyl-containing compounds. In addition it includes
poppy NADPH-dependent salutaridine reductase which
catalyzes the stereospecific reduction of salutaridine
to 7(S)-salutaridinol in the biosynthesis of morphine,
and Arabidopsis SDR1,a menthone reductase, which
catalyzes the reduction of menthone to neomenthol, a
compound with antimicrobial activity; SDR1 can also
carry out neomenthol oxidation. 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

members of the classical SDR family, with a canonical
active site triad (and also an active site Asn) and a
typical Gly-rich NAD-binding motif. SDRs are a
functionally diverse family of oxidoreductases that have

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.

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

which convert retinol to retinal, a property that

well as Asn (or Ser). Some SDR family members, including

>gnl|CDD|185752 cd08961, GH64-TLP-SF, glycoside hydrolase family 64
(beta-1,3-glucanases which produce specific
pentasaccharide oligomers) and thaumatin-like proteins.
This superfamily includes glycoside hydrolases of
family 64 (GH64), these are mostly bacterial
beta-1,3-glucanases which cleave long-chain
polysaccharide beta-1,3-glucans, into specific
pentasaccharide oligomers and are implicated in fungal
cell wall degradation. Also included in this
superfamily are thaumatin, the sweet-tasting protein
from the African berry Thaumatococcus daniellii, and
thaumatin-like proteins (TLPs) which are involved in
host defense and a wide range of developmental
processes in fungi, plants, and animals. Like GH64s,
some TLPs also hydrolyze the beta-1,3-glucans of the
type commonly found in fungal walls. Plant TLPs are
classified as pathogenesis-related (PR) protein family
5 (PR5), their expression is induced by environmental
stresses such as pathogen/pest attack, drought and
cold. Several members of the plant TLP family have been
reported as food allergens from fruits, and pollen
allergens from conifers. Streptomyces matensis
laminaripentaose-producing, beta-1,3-glucanase
(GH64-LPHase), and TLPs have in common, a core
N-terminal barrel domain (domain I) composed of 10
beta-strands, two coming from the C-terminal region of
the protein. In TLPs, this core domain is flanked by
two shorter domains (domains II and III). Small TLPs,
such as Triticum aestivum thaumatin-like xylanase
inhibitor, have a deletion in the third domain (domain
II). GH64-LPHase has a second C-terminal domain which
corresponds positional to, but is much larger than,
domain III of TLP. GH64-LPHase and TLPs are described
as crescent-fold structures. Critical functional
residues, common to GH64-LPHase and TLPs are a Glu and
an Asp residue. LPHase has an electronegative,
substrate-binding cleft and the afore mentioned
conserved Glu and Asp residues are the catalytic
residues essential for beta-1,3-glucan cleavage. In
TLPs, these residues are two of the four conserved
residues which contribute to the strong electronegative
character of the cleft which is associated with the
antifungal activity of TLPs.

A_reductase (ChcA)_like, classical (c) SDRs. This
subgroup contains classical SDR proteins, including
members identified as 1-cyclohexenylcarbonyl coenzyme A
reductase. ChcA of Streptomyces collinus is implicated
in the final reduction step of shikimic acid to
ansatrienin. ChcA shows sequence similarity to the SDR
family of NAD-binding proteins, but it lacks the
conserved Tyr of the characteristic catalytic site. This
subgroup also contains the NADH-dependent
enoyl-[acyl-carrier-protein(ACP)] reductase FabL from
Bacillus subtilis. This enzyme participates in bacterial
fatty acid synthesis, in type II fatty-acid synthases
and catalyzes the last step in each elongation cycle.
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.

Sniffer in the prevention of neurodegeneration due to

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)

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.
