>gnl|CDD|161904 TIGR00507, aroE, shikimate 5-dehydrogenase. This model finds
proteins from prokaryotes and functionally equivalent
domains from larger, multifunctional proteins of fungi
and plants. Below the trusted cutoff of 180, but above
the noise cutoff of 20, are the putative shikimate
dehydrogenases of Thermotoga maritima and Mycobacterium
tuberculosis, and uncharacterized paralogs of shikimate
dehydrogenase from E. coli and H. influenzae. The
related enzyme quinate 5-dehydrogenase scores below the
noise cutoff. A neighbor-joining tree, constructed with
quinate 5-dehydrogenases as the outgroup, shows the
Clamydial homolog as clustering among the shikimate
dehydrogenases, although the sequence is unusual in the
degree of sequence divergence and the presence of an
additional N-terminal domain [Amino acid biosynthesis,
Aromatic amino acid family].

>gnl|CDD|133443 cd01065, NAD_bind_Shikimate_DH, NAD(P) binding domain of Shikimate
dehydrogenase. Shikimate dehydrogenase (DH) is an amino
acid DH family member. Shikimate pathway links
metabolism of carbohydrates to de novo biosynthesis of
aromatic amino acids, quinones and folate. It is
essential in plants, bacteria, and fungi but absent in
mammals, thus making enzymes involved in this pathway
ideal targets for broad spectrum antibiotics and
herbicides. Shikimate DH catalyzes the reduction of
3-hydroshikimate to shikimate using the cofactor NADH.
Amino acid DH-like NAD(P)-binding domains are members of
the Rossmann fold superfamily and include glutamate,
leucine, and phenylalanine DHs, methylene
tetrahydrofolate DH, methylene-tetrahydromethanopterin
DH, methylene-tetrahydropholate DH/cyclohydrolase,
Shikimate DH-like proteins, malate oxidoreductases, and
glutamyl tRNA reductase. Amino acid DHs catalyze the
deamination of amino acids to keto acids with NAD(P)+ as
a cofactor. The NAD(P)-binding Rossmann fold superfamily
includes a wide variety of protein families including
NAD(P)- binding domains of alcohol DHs,
tyrosine-dependent oxidoreductases,
glyceraldehyde-3-phosphate DH, lactate/malate DHs,
formate/glycerate DHs, siroheme synthases,
6-phosphogluconate DHs, amino acid DHs, repressor rex,
NAD-binding potassium channel domain, CoA-binding, and
ornithine cyclodeaminase-like domains. These domains
have an alpha-beta-alpha configuration. NAD binding
involves numerous hydrogen and van der Waals contacts.

>gnl|CDD|240631 cd12154, FDH_GDH_like, Formate/glycerate dehydrogenases, D-specific
2-hydroxy acid dehydrogenases and related
dehydrogenases. The formate/glycerate dehydrogenase
like family contains a diverse group of enzymes such as
formate dehydrogenase (FDH), glycerate dehydrogenase
(GDH), D-lactate dehydrogenase, L-alanine dehydrogenase,
and S-Adenosylhomocysteine hydrolase, that share a
common 2-domain structure. Despite often low sequence
identity, these proteins typically have a characteristic
arrangement of 2 similar domains of the alpha/beta
Rossmann fold NAD+ binding form. The NAD(P) binding
domain is inserted within the linear sequence of the
mostly N-terminal catalytic domain. Structurally, these
domains are connected by extended alpha helices and
create a cleft in which NAD(P) is bound, primarily to
the C-terminal portion of the 2nd (internal) domain.
While many members of this family are dimeric, alanine
DH is hexameric and phosphoglycerate DH is tetrameric.
2-hydroxyacid dehydrogenases are enzymes that catalyze
the conversion of a wide variety of D-2-hydroxy acids to
their corresponding keto acids. The general mechanism is
(R)-lactate + acceptor to pyruvate + reduced acceptor.
Formate dehydrogenase (FDH) catalyzes the NAD+-dependent
oxidation of formate ion to carbon dioxide with the
concomitant reduction of NAD+ to NADH. FDHs of this
family contain no metal ions or prosthetic groups.
Catalysis occurs though direct transfer of a hydride ion
to NAD+ without the stages of acid-base catalysis
typically found in related dehydrogenases.

>gnl|CDD|176178 cd05188, MDR, Medium chain reductase/dehydrogenase
(MDR)/zinc-dependent alcohol dehydrogenase-like family.
The medium chain reductase/dehydrogenases
(MDR)/zinc-dependent alcohol dehydrogenase-like family,
which contains the zinc-dependent alcohol dehydrogenase
(ADH-Zn) and related proteins, is a diverse group of
proteins related to the first identified member, class I
mammalian ADH. MDRs display a broad range of activities
and are distinguished from the smaller short chain
dehydrogenases (~ 250 amino acids vs. the ~ 350 amino
acids of the MDR). The MDR proteins have 2 domains: a
C-terminal NAD(P) binding-Rossmann fold domain of a
beta-alpha form and an N-terminal catalytic domain with
distant homology to GroES. The MDR group contains a
host of activities, including the founding alcohol
dehydrogenase (ADH) , quinone reductase, sorbitol
dehydrogenase, formaldehyde dehydrogenase, butanediol
DH, ketose reductase, cinnamyl reductase, and numerous
others. The zinc-dependent alcohol dehydrogenases (ADHs)
catalyze the NAD(P)(H)-dependent interconversion of
alcohols to aldehydes or ketones. ADH-like proteins
typically form dimers (typically higher plants, mammals)
or tetramers (yeast, bacteria), and generally have 2
tightly bound zinc atoms per subunit, a catalytic zinc
at the active site and a structural zinc in a lobe of
the catalytic domain. The active site zinc is
coordinated by a histidine, two cysteines, and a water
molecule. The second zinc seems to play a structural
role, affects subunit interactions, and is typically
coordinated by 4 cysteines. Other MDR members have only
a catalytic zinc, and some contain no coordinated zinc.

(SAHH, AdoHycase) catalyzes the hydrolysis of
S-adenosyl-L-homocysteine (AdoHyc) to form adenosine
(Ado) and homocysteine (Hcy). The equilibrium lies far
on the side of AdoHyc synthesis, but in nature the
removal of Ado and Hyc is sufficiently fast, so that the

>gnl|CDD|176222 cd08261, Zn_ADH7, Alcohol dehydrogenases of the MDR family. This
group contains members identified as related to
zinc-dependent alcohol dehydrogenase and other members
of the MDR family. The medium chain
dehydrogenases/reductase (MDR)/zinc-dependent alcohol
dehydrogenase-like family, which contains the
zinc-dependent alcohol dehydrogenase (ADH-Zn) and
related proteins, is a diverse group of proteins related
to the first identified member, class I mammalian ADH.
MDRs display a broad range of activities and are
distinguished from the smaller short chain
dehydrogenases (~ 250 amino acids vs. the ~ 350 amino
acids of the MDR). The MDR proteins have 2 domains: a
C-terminal NAD(P)-binding Rossmann fold domain of a
beta-alpha form and an N-terminal catalytic domain with
distant homology to GroES. The MDR group includes
various activities, including the founding alcohol
dehydrogenase (ADH), quinone reductase, sorbitol
dehydrogenase, formaldehyde dehydrogenase, butanediol
DH, ketose reductase, cinnamyl reductase, and numerous
others. The zinc-dependent alcohol dehydrogenases (ADHs)
catalyze the NAD(P)(H)-dependent interconversion of
alcohols to aldehydes or ketones. Active site zinc has a
catalytic role, while structural zinc aids in stability.
ADH-like proteins typically form dimers (typically
higher plants, mammals) or tetramers (yeast, bacteria),
and generally have 2 tightly bound zinc atoms per
subunit. The active site zinc is coordinated by a
histidine, two cysteines, and a water molecule. The
second zinc seems to play a structural role, affects
subunit interactions, and is typically coordinated by 4
cysteines.

[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.

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,

>gnl|CDD|176182 cd05279, Zn_ADH1, Liver alcohol dehydrogenase and related
zinc-dependent alcohol dehydrogenases.
NAD(P)(H)-dependent oxidoreductases are the major
enzymes in the interconversion of alcohols and
aldehydes, or ketones. Alcohol dehydrogenase in the
liver converts ethanol and NAD+ to acetaldehyde and
NADH, while in yeast and some other microorganisms ADH
catalyzes the conversion acetaldehyde to ethanol in
alcoholic fermentation. There are 7 vertebrate ADH 7
classes, 6 of which have been identified in humans.
Class III, glutathione-dependent formaldehyde
dehydrogenase, has been identified as the primordial
form and exists in diverse species, including plants,
micro-organisms, vertebrates, and invertebrates. Class
I, typified by liver dehydrogenase, is an evolving
form. Gene duplication and functional specialization of
ADH into ADH classes and subclasses created numerous
forms in vertebrates. For example, the A, B and C
(formerly alpha, beta, gamma) human class I subunits
have high overall structural similarity, but differ in
the substrate binding pocket and therefore in substrate
specificity. In human ADH catalysis, the zinc ion helps
coordinate the alcohol, followed by deprotonation of a
histidine (His-51), the ribose of NAD, a serine
(Ser-48), then the alcohol, which allows the transfer of
a hydride to NAD+, creating NADH and a zinc-bound
aldehyde or ketone. In yeast and some bacteria, the
active site zinc binds an aldehyde, polarizing it, and
leading to the reverse reaction. ADH is a member of the
medium chain alcohol dehydrogenase family (MDR), which
has a NAD(P)(H)-binding domain in a Rossmann fold of an
beta-alpha form. The NAD(H)-binding region is comprised
of 2 structurally similar halves, each of which contacts
a mononucleotide. A GxGxxG motif after the first
mononucleotide contact half allows the close contact of
the coenzyme with the ADH backbone. The N-terminal
catalytic domain has a distant homology to GroES.
These proteins typically form dimers (typically higher
plants, mammals) or tetramers (yeast, bacteria), and
have 2 tightly bound zinc atoms per subunit, a catalytic
zinc at the active site and a structural zinc in a lobe
of the catalytic domain. NAD(H) binding occurs in the
cleft between the catalytic and coenzyme-binding domains
at the active site, and coenzyme binding induces a
conformational closing of this cleft. Coenzyme binding
typically precedes and contributes to substrate binding.

tetrameric, classical SDR that catalyzes the
NAD-dependent conversion of (-)-secoisolariciresinol to
(-)-matairesinol via a (-)-lactol intermediate.
(-)-Matairesinol is an intermediate to various
8'-lignans, including the cancer-preventive mammalian
lignan, and those involved in vascular plant defense.
This subgroup also includes rice momilactone A synthase
which catalyzes the conversion of
3beta-hydroxy-9betaH-pimara-7,15-dien-19,6beta-olide
into momilactone A, Arabidopsis ABA2 which during
abscisic acid (ABA) biosynthesis, catalyzes the
conversion of xanthoxin to abscisic aldehyde and, maize
Tasselseed2 which participate in the maize sex

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, 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.

dehydrogenase-like, classical(c)-like SDRs. Beta
oxidation of fatty acids in eukaryotes occurs by a
four-reaction cycle, that may take place in mitochondria
or in peroxisomes. (3R)-hydroxyacyl-CoA dehydrogenase is
part of rat peroxisomal multifunctional MFE-2, it is a
member of the NAD-dependent SDRs, but contains an
additional small C-terminal domain that completes the
active site pocket and participates in dimerization. The
atypical, additional C-terminal extension allows for
more extensive dimerization contact than other SDRs.
MFE-2 catalyzes the second and third reactions of the
peroxisomal beta oxidation cycle. Proteins in this
subgroup have a typical catalytic triad, but have a His
in place of the usual upstream Asn. This subgroup also
contains members identified as 17-beta-hydroxysteroid
dehydrogenases, including human peroxisomal
17-beta-hydroxysteroid dehydrogenase type 4 (17beta-HSD
type 4, aka MFE-2, encoded by HSD17B4 gene) which is
involved in fatty acid beta-oxidation and steroid
metabolism. This subgroup also includes two SDR domains
of the Neurospora crassa and Saccharomyces cerevisiae
multifunctional beta-oxidation protein (MFP, aka Fox2).
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.

connected by a long alpha helical stretch, each
resembling a Rossmann fold NAD-binding domain. The
NAD-binding domain is inserted within the linear
sequence of the more divergent catalytic domain. Ligand
binding and active site residues are found in the cleft
between the subdomains. L-AlaDH is typically hexameric
and is critical in carbon and nitrogen metabolism in
micro-organisms.

>gnl|CDD|187635 cd08930, SDR_c8, classical (c) SDR, subgroup 8. This subgroup has
a fairly well conserved active site tetrad and domain
size of the classical SDRs, but has an atypical
NAD-binding motif ([ST]G[GA]XGXXG). 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.

dehydrogenase, N-benzyl-3-pyrrolidinol dehydrogenase,
and other MDR family members. This group contains
enzymes of the zinc-dependent alcohol dehydrogenase
family, including members (aka MDR) identified as
6-hydroxycyclohex-1-ene-1-carboxyl-CoA dehydrogenase and
N-benzyl-3-pyrrolidinol dehydrogenase.
6-hydroxycyclohex-1-ene-1-carboxyl-CoA dehydrogenase
catalyzes the conversion of
6-Hydroxycyclohex-1-enecarbonyl-CoA and NAD+ to
6-Ketoxycyclohex-1-ene-1-carboxyl-CoA,NADH, and H+. This
group displays the characteristic catalytic and
structural zinc sites of the zinc-dependent alcohol
dehydrogenases. NAD(P)(H)-dependent oxidoreductases are
the major enzymes in the interconversion of alcohols and
aldehydes, or ketones. Alcohol dehydrogenase in the
liver converts ethanol and NAD+ to acetaldehyde and
NADH, while in yeast and some other microorganisms ADH
catalyzes the conversion acetaldehyde to ethanol in
alcoholic fermentation. ADH is a member of the medium
chain alcohol dehydrogenase family (MDR), which have a
NAD(P)(H)-binding domain in a Rossmann fold of a
beta-alpha form. The NAD(H)-binding region is comprised
of 2 structurally similar halves, each of which contacts
a mononucleotide. A GxGxxG motif after the first
mononucleotide contact half allows the close contact of
the coenzyme with the ADH backbone. The N-terminal
catalytic domain has a distant homology to GroES. These
proteins typically form dimers (typically higher plants,
mammals) or tetramers (yeast, bacteria), and have 2
tightly bound zinc atoms per subunit, a catalytic zinc
at the active site and a structural zinc in a lobe of
the catalytic domain. NAD(H)-binding occurs in the cleft
between the catalytic and coenzyme-binding domains at
the active site, and coenzyme binding induces a
conformational closing of this cleft. Coenzyme binding
typically precedes and contributes to substrate binding.
In human ADH catalysis, the zinc ion helps coordinate
the alcohol, followed by deprotonation of a histidine,
the ribose of NAD, a serine, then the alcohol, which
allows the transfer of a hydride to NAD+, creating NADH
and a zinc-bound aldehyde or ketone. In yeast and some
bacteria, the active site zinc binds an aldehyde,
polarizing it, and leading to the reverse reaction.

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|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.

Members identified as zinc-dependent alcohol
dehydrogenases and quinone oxidoreductase. QOR catalyzes
the conversion of a quinone + NAD(P)H to a hydroquinone
+ NAD(P)+. Quinones are cyclic diones derived from
aromatic compounds. Membrane bound QOR actin the
respiratory chains of bacteria and mitochondria, while
soluble QOR acts to protect from toxic quinones (e.g.
DT-diaphorase) or as a soluble eye-lens protein in some
vertebrates (e.g. zeta-crystalin). QOR reduces quinones
through a semi-quinone intermediate via a
NAD(P)H-dependent single electron transfer. QOR is a
member of the medium chain dehydrogenase/reductase
family, but lacks the zinc-binding sites of the
prototypical alcohol dehydrogenases of this group.
NAD(P)(H)-dependent oxidoreductases are the major
enzymes in the interconversion of alcohols and
aldehydes, or ketones. Alcohol dehydrogenase in the
liver converts ethanol and NAD+ to acetaldehyde and
NADH, while in yeast and some other microorganisms ADH
catalyzes the conversion acetaldehyde to ethanol in
alcoholic fermentation. ADH is a member of the medium
chain alcohol dehydrogenase family (MDR), which has a
NAD(P)(H)-binding domain in a Rossmann fold of a
beta-alpha form. The NAD(H)-binding region is comprised
of 2 structurally similar halves, each of which contacts
a mononucleotide. A GxGxxG motif after the first
mononucleotide contact half allows the close contact of
the coenzyme with the ADH backbone. The N-terminal
catalytic domain has a distant homology to GroES. These
proteins typically form dimers (typically higher plants,
mammals) or tetramers (yeast, bacteria), and have 2
tightly bound zinc atoms per subunit, a catalytic zinc
at the active site and a structural zinc in a lobe of
the catalytic domain. NAD(H) binding occurs in the
cleft between the catalytic and coenzyme-binding domains
at the active site, and coenzyme binding induces a
conformational closing of this cleft. Coenzyme binding
typically precedes and contributes to substrate binding.
In human ADH catalysis, the zinc ion helps coordinate
the alcohol, followed by deprotonation of a histidine,
the ribose of NAD, a serine, then the alcohol, which
allows the transfer of a hydride to NAD+, creating NADH
and a zinc-bound aldehyde or ketone. In yeast and some
bacteria, the active site zinc binds an aldehyde,
polarizing it, and leading to the reverse reaction.

(MDR)/zinc-dependent alcohol dehydrogenase-like family,
which contains the zinc-dependent alcohol dehydrogenase
(ADH-Zn) and related proteins, is a diverse group of
proteins related to the first identified member, class I
mammalian ADH. MDRs display a broad range of activities
and are distinguished from the smaller short chain
dehydrogenases (~ 250 amino acids vs. the ~ 350 amino
acids of the MDR). The MDR proteins have 2 domains: a
C-terminal NAD(P)-binding Rossmann fold domain of a
beta-alpha form and an N-terminal catalytic domain with
distant homology to GroES. The MDR group contains a
host of activities, including the founding alcohol
dehydrogenase (ADH), quinone reductase, sorbitol
dehydrogenase, formaldehyde dehydrogenase, butanediol
DH, ketose reductase, cinnamyl reductase, and numerous
others. The zinc-dependent alcohol dehydrogenases (ADHs)
catalyze the NAD(P)(H)-dependent interconversion of
alcohols to aldehydes or ketones. Active site zinc has
a catalytic role, while structural zinc aids in
stability. ADH-like proteins typically form dimers
(typically higher plants, mammals) or tetramers (yeast,
bacteria), and generally have 2 tightly bound zinc atoms
per subunit. The active site zinc is coordinated by a
histidine, two cysteines, and a water molecule. The
second zinc seems to play a structural role, affects
subunit interactions, and is typically coordinated by 4
cysteines.

oxidative deamination of an amino acid to its keto acid
and ammonia with concomitant reduction of NADP+. For
example, leucine DH catalyzes the reversible oxidative
deamination of L-leucine and several other straight or

methylene-tetrahydropholate DH/cyclohydrolase, Shikimate
DH-like proteins, malate oxidoreductases, and glutamyl
tRNA reductase. Amino acid DHs catalyze the deamination
of amino acids to keto acids with NAD(P)+ as a cofactor.
The NAD(P)-binding Rossmann fold superfamily includes a
wide variety of protein families including NAD(P)-
binding domains of alcohol DHs, tyrosine-dependent
oxidoreductases, glyceraldehyde-3-phosphate DH,

Members identified as glutathione-dependent formaldehyde
dehydrogenase(FDH), a member of the zinc
dependent/medium chain alcohol dehydrogenase family.
FDH converts formaldehyde and NAD(P) to formate and
NAD(P)H. The initial step in this process the
spontaneous formation of a S-(hydroxymethyl)glutathione
adduct from formaldehyde and glutathione, followed by
FDH-mediated oxidation (and detoxification) of the
adduct to S-formylglutathione. MDH family uses NAD(H)
as a cofactor in the interconversion of alcohols and
aldehydes or ketones. Like many zinc-dependent alcohol
dehydrogenases (ADH) of the medium chain alcohol
dehydrogenase/reductase family (MDR), these FDHs form
dimers, with 4 zinc ions per dimer. The medium chain
alcohol dehydrogenase family (MDR) have a
NAD(P)(H)-binding domain in a Rossmann fold of a
beta-alpha form. The N-terminal region typically has an
all-beta catalytic domain. These proteins typically form
dimers (typically higher plants, mammals) or tetramers
(yeast, bacteria), and have 2 tightly bound zinc atoms
per subunit. Alcohol dehydrogenase in the liver
converts ethanol and NAD+ to acetaldehyde and NADH,
while in yeast and some other microorganisms ADH
catalyzes the conversion acetaldehyde to ethanol in
alcoholic fermentation. ADH is a member of the medium
chain alcohol dehydrogenase family (MDR), which have a
NAD(P)(H)-binding domain in a Rossmann fold of a
beta-alpha form. The NAD(H)-binding region is comprised
of 2 structurally similar halves, each of which contacts
a mononucleotide. A GxGxxG motif after the first
mononucleotide contact half allows the close contact of
the coenzyme with the ADH backbone. The N-terminal
catalytic domain has a distant homology to GroES.
These proteins typically form dimers (typically higher
plants, mammals) or tetramers (yeast, bacteria), and
have 2 tightly bound zinc atoms per subunit, a catalytic
zinc at the active site and a structural zinc in a lobe
of the catalytic domain. NAD(H) binding occurs in the
cleft between the catalytic and coenzyme-binding
domains at the active site, and coenzyme binding induces
a conformational closing of this cleft. Coenzyme binding
typically precedes and contributes to substrate binding.

proteins of the D-specific 2-hydroxy dehydrogenase
family. This group contains a variety of proteins
variously identified as glycerate dehydrogenase (GDH,
aka Hydroxypyruvate Reductase) and other enzymes of the
2-hydroxyacid dehydrogenase family. GDH catalyzes the
reversible reaction of (R)-glycerate + NAD+ to
hydroxypyruvate + NADH + H+. 2-hydroxyacid
dehydrogenases catalyze the conversion of a wide variety
of D-2-hydroxy acids to their corresponding keto acids.
The general mechanism is (R)-lactate + acceptor to
pyruvate + reduced acceptor. Formate/glycerate and
related dehydrogenases of the D-specific 2-hydroxyacid
dehydrogenase superfamily include groups such as formate
dehydrogenase, glycerate dehydrogenase, L-alanine
dehydrogenase, and S-adenosylhomocysteine hydrolase.
Despite often low sequence identity, these proteins
typically have a characteristic arrangement of 2 similar
subdomains of the alpha/beta Rossmann-fold NAD+ binding
form. The NAD+ binding domain is inserted within the
linear sequence of the mostly N-terminal catalytic
domain, which has a similar domain structure to the
internal NAD binding domain. Structurally, these domains
are connected by extended alpha helices and create a
cleft in which NAD is bound, primarily to the C-terminal
portion of the 2nd (internal) domain. Some related
proteins have similar structural subdomain but with a
tandem arrangement of the catalytic and NAD-binding
subdomains in the linear sequence. While many members of
this family are dimeric, alanine DH is hexameric and
phosphoglycerate DH is tetrameric.

>gnl|CDD|133452 cd05213, NAD_bind_Glutamyl_tRNA_reduct, NADP-binding domain of
glutamyl-tRNA reductase. Glutamyl-tRNA reductase
catalyzes the conversion of glutamyl-tRNA to
glutamate-1-semialdehyde, initiating the synthesis of
tetrapyrrole. Whereas tRNAs are generally associated
with peptide bond formation in protein translation, here
the tRNA activates glutamate in the initiation of
tetrapyrrole biosynthesis in archaea, plants and many
bacteria. In the first step, activated glutamate is
reduced to glutamate-1-semi-aldehyde via the NADPH
dependent glutamyl-tRNA reductase. Glutamyl-tRNA
reductase forms a V-shaped dimer. Each monomer has 3
domains: an N-terminal catalytic domain, a classic
nucleotide binding domain, and a C-terminal dimerization
domain. Although the representative structure 1GPJ lacks
a bound NADPH, a theoretical binding pocket has been
described. (PMID 11172694). Amino acid dehydrogenase
(DH)-like NAD(P)-binding domains are members of the
Rossmann fold superfamily and include glutamate,
leucine, and phenylalanine DHs, methylene
tetrahydrofolate DH, methylene-tetrahydromethanopterin
DH, methylene-tetrahydropholate DH/cyclohydrolase,
Shikimate DH-like proteins, malate oxidoreductases, and
glutamyl tRNA reductase. Amino acid DHs catalyze the
deamination of amino acids to keto acids with NAD(P)+ as
a cofactor. The NAD(P)-binding Rossmann fold superfamily
includes a wide variety of protein families including
NAD(P)- binding domains of alcohol DHs,
tyrosine-dependent oxidoreductases,
glyceraldehyde-3-phosphate DH, lactate/malate DHs,
formate/glycerate DHs, siroheme synthases,
6-phosphogluconate DH, amino acid DHs, repressor rex,
NAD-binding potassium channel domain, CoA-binding, and
ornithine cyclodeaminase-like domains. These domains
have an alpha-beta-alpha configuration. NAD binding
involves numerous hydrogen and van der Waals contacts.

>gnl|CDD|187629 cd05371, HSD10-like_SDR_c, 17hydroxysteroid dehydrogenase type 10
(HSD10)-like, classical (c) SDRs. HSD10, also known as
amyloid-peptide-binding alcohol dehydrogenase (ABAD),
was previously identified as a L-3-hydroxyacyl-CoA
dehydrogenase, HADH2. In fatty acid metabolism, HADH2
catalyzes the third step of beta-oxidation, the
conversion of a hydroxyl to a keto group in the
NAD-dependent oxidation of L-3-hydroxyacyl CoA. In
addition to alcohol dehydrogenase and HADH2 activites,
HSD10 has steroid dehydrogenase activity. Although the
mechanism is unclear, HSD10 is implicated in the
formation of amyloid beta-petide in the brain (which is
linked to the development of Alzheimer's disease).
Although HSD10 is normally concentrated in the
mitochondria, in the presence of amyloid beta-peptide it
translocates into the plasma membrane, where it's action
may generate cytotoxic aldehydes and may lower estrogen
levels through its use of 17-beta-estradiol as a
substrate. HSD10 is a member of the SRD family, but
differs from other SDRs by the presence of two
insertions of unknown function. 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.

(7 alpha-HSDH), classical (c) SDRs. This bacterial
subgroup contains 7 alpha-HSDHs, including Escherichia
coli 7 alpha-HSDH. 7 alpha-HSDH, a member of the SDR
family, catalyzes the NAD+ -dependent dehydrogenation of
a hydroxyl group at position 7 of the steroid skeleton
of bile acids. In humans the two primary bile acids are
cholic and chenodeoxycholic acids, these are formed from
cholesterol in the liver. Escherichia coli 7 alpha-HSDH
dehydroxylates these bile acids in the human intestine.
Mammalian 7 alpha-HSDH activity has been found in
livers. 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

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

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

there is often an upstream Ser (Ser-138, 15-PGDH
numbering) and/or an Asn (Asn-107, 15-PGDH numbering) or

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

ACCD catalyzes the conversion of
1-aminocyclopropane-1-carboxylate to alpha-ketobutyrate
and ammonia. Tryptophan synthase folds into a tetramer,
where the beta chain is the catalytic PLP-binding
subunit and catalyzes the formation of L-tryptophan from

that catalyzes condensation of serine and homocysteine
to cystathionine. CS is a homodimer that catalyzes the

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

classical (c) SDRs. Dihydropteridine reductase is an
NAD-binding protein related to the SDRs. It converts
dihydrobiopterin into tetrahydrobiopterin, a cofactor
necessary in catecholamines synthesis. Dihydropteridine
reductase has the YXXXK of these tyrosine-dependent
oxidoreductases, but lacks the typical upstream Asn and
Ser catalytic residues. 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|176221 cd08260, Zn_ADH6, Alcohol dehydrogenases of the MDR family.
NAD(P)(H)-dependent oxidoreductases are the major
enzymes in the interconversion of alcohols and
aldehydes, or ketones. This group has the characteristic
catalytic and structural zinc sites of the
zinc-dependent alcohol dehydrogenases. Alcohol
dehydrogenase in the liver converts ethanol and NAD+ to
acetaldehyde and NADH, while in yeast and some other
microorganisms ADH catalyzes the conversion acetaldehyde
to ethanol in alcoholic fermentation. ADH is a member of
the medium chain alcohol dehydrogenase family (MDR),
which has a NAD(P)(H)-binding domain in a Rossmann fold
of a beta-alpha form. The NAD(H)-binding region is
comprised of 2 structurally similar halves, each of
which contacts a mononucleotide. A GxGxxG motif after
the first mononucleotide contact half allows the close
contact of the coenzyme with the ADH backbone. The
N-terminal catalytic domain has a distant homology to
GroES. These proteins typically form dimers (typically
higher plants, mammals) or tetramers (yeast, bacteria),
and have 2 tightly bound zinc atoms per subunit, a
catalytic zinc at the active site and a structural zinc
in a lobe of the catalytic domain. NAD(H)-binding occurs
in the cleft between the catalytic and coenzyme-binding
domains at the active site, and coenzyme binding induces
a conformational closing of this cleft. Coenzyme binding
typically precedes and contributes to substrate binding.
In human ADH catalysis, the zinc ion helps coordinate
the alcohol, followed by deprotonation of a histidine,
the ribose of NAD, a serine, then the alcohol, which
allows the transfer of a hydride to NAD+, creating NADH
and a zinc-bound aldehyde or ketone. In yeast and some
bacteria, the active site zinc binds an aldehyde,
polarizing it, and leading to the reverse reaction.

>gnl|CDD|187605 cd05347, Ga5DH-like_SDR_c, gluconate 5-dehydrogenase (Ga5DH)-like,
classical (c) SDRs. Ga5DH catalyzes the NADP-dependent
conversion of carbon source D-gluconate and
5-keto-D-gluconate. This SDR subgroup has a classical
Gly-rich NAD(P)-binding motif and a conserved active
site tetrad pattern. However, it has been proposed that
Arg104 (Streptococcus suis Ga5DH numbering), as well as
an active site Ca2+, play a critical role in catalysis.
In addition to Ga5DHs this subgroup contains Erwinia
chrysanthemi KduD which is involved in pectin
degradation, and is a putative
2,5-diketo-3-deoxygluconate dehydrogenase. 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.
