>gnl|CDD|176250 cd08290, ETR, 2-enoyl thioester reductase (ETR). 2-enoyl thioester
reductase (ETR) catalyzes the NADPH-dependent conversion
of trans-2-enoyl acyl carrier protein/coenzyme A
(ACP/CoA) to acyl-(ACP/CoA) in fatty acid synthesis.
2-enoyl thioester reductase activity has been linked in
Candida tropicalis as essential in maintaining
mitiochondrial respiratory function. This ETR family is
a part of the medium chain dehydrogenase/reductase
family, but lack the zinc coordination sites
characteristic of the alcohol dehydrogenases in this
family. 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. 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. Candida tropicalis
enoyl thioester reductase (Etr1p) catalyzes the
NADPH-dependent reduction of trans-2-enoyl thioesters in
mitochondrial fatty acid synthesis. Etr1p forms
homodimers, with each subunit containing a
nucleotide-binding Rossmann fold domain and a catalytic
domain.

>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.

>gnl|CDD|176203 cd08241, QOR1, Quinone oxidoreductase (QOR). 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 acts in 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.

>gnl|CDD|176229 cd08268, MDR2, Medium chain dehydrogenases/reductase
(MDR)/zinc-dependent alcohol dehydrogenase-like family.
This group is a member of the medium chain
dehydrogenases/reductase (MDR)/zinc-dependent alcohol
dehydrogenase-like family, but lacks the zinc-binding
sites of the zinc-dependent alcohol dehydrogenases. 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 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.

>gnl|CDD|176191 cd05289, MDR_like_2, alcohol dehydrogenase and quinone
reductase-like medium chain degydrogenases/reductases.
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.

identified as possible enoyl reductase of the MDR
family. 2-enoyl thioester reductase (ETR) catalyzes the
NADPH-dependent dependent conversion of trans-2-enoyl
acyl carrier protein/coenzyme A (ACP/CoA) to
acyl-(ACP/CoA) in fatty acid synthesis. 2-enoyl
thioester reductase activity has been linked in Candida
tropicalis as essential in maintaining mitiochondrial
respiratory function. This ETR family is a part of the
medium chain dehydrogenase/reductase family, but lack
the zinc coordination sites characteristic of the
alcohol dehydrogenases in this family.

quinone reductase activity (QOR). Zeta-crystallin is a
eye lens protein with NADP-dependent quinone reductase
activity (QOR). It has been cited as a structural
component in mammalian eyes, but also has homology to
quinone reductases in unrelated species. QOR catalyzes
the conversion of a quinone and NAD(P)H to a
hydroquinone and NAD(P+. Quinones are cyclic diones
derived from aromatic compounds. Membrane bound QOR acts
in 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.
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. 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.

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

DH, ketose reductase, cinnamyl reductase, and numerous
others. The zinc-dependent alcohol dehydrogenases (ADHs)

a catalytic role, while structural zinc aids in

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.

>gnl|CDD|176180 cd05276, p53_inducible_oxidoreductase, PIG3 p53-inducible quinone
oxidoreductase. PIG3 p53-inducible quinone
oxidoreductase, a medium chain dehydrogenase/reductase
family member, acts in the apoptotic pathway. PIG3
reduces ortho-quinones, but its apoptotic activity has
been attributed to oxidative stress generation, since
overexpression of PIG3 accumulates reactive oxygen
species. PIG3 resembles the MDR family member quinone
reductases, which catalyze the reduction of quinone to
hydroxyquinone. 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.

contains arabinose dehydrogenase (AraDH) and related

chain dehydrogenase/reductase family and catalyzes the
NAD(P)-dependent oxidation of D-arabinose and other
pentoses, the initial step in the metabolism of
d-arabinose into 2-oxoglutarate. Like the alcohol
dehydrogenases, AraDH binds a zinc in the catalytic
cleft as well as a distal structural zinc. AraDH forms
homotetramers as a dimer of dimers. AraDH replaces a
conserved catalytic His with replace with Arg, compared
to the canonical ADH site. 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

>gnl|CDD|176179 cd05195, enoyl_red, enoyl reductase of polyketide synthase.
Putative enoyl reductase of polyketide synthase.
Polyketide synthases produce polyketides in step by step
mechanism that is similar to fatty acid synthesis. Enoyl
reductase reduces a double to single bond. Erythromycin
is one example of a polyketide generated by 3 complex
enzymes (megasynthases). 2-enoyl thioester reductase
(ETR) catalyzes the NADPH-dependent dependent conversion
of trans-2-enoyl acyl carrier protein/coenzyme A
(ACP/CoA) to acyl-(ACP/CoA) in fatty acid synthesis.
2-enoyl thioester reductase activity has been linked in
Candida tropicalis as essential in maintaining
mitiochondrial respiratory function. This ETR family is
a part of the medium chain dehydrogenase/reductase
family, but lack the zinc coordination sites
characteristic of the alcohol dehydrogenases in this
family. 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. 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.

catalytic and structural zinc sites of the
zinc-dependent alcohol dehydrogenases. Alcohol
dehydrogenase in the liver converts ethanol and NAD+ to

contact of the coenzyme with the ADH backbone. The
N-terminal catalytic domain has a distant homology to

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.

the last step of monolignal metabolism in plant cells

CAD family members are also found in non-plant species,

which contains the zinc-dependent alcohol dehydrogenase

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

DH, ketose reductase, cinnamyl reductase, and numerous
others. The zinc-dependent alcohol dehydrogenases (ADHs)
catalyze the NAD(P)(H)-dependent interconversion of

a catalytic role, while structural zinc aids in
stability. ADH-like proteins typically form dimers
(typically higher plants, mammals) or tetramers (yeast,

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.

Glutathione-dependent formaldehyde dehydrogenases (FDHs,
Class III ADH) are members 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. 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. Class III ADH are also known as
glutathione-dependent formaldehyde dehydrogenase (FDH),
which convert aldehydes to corresponding carboxylic acid
and alcohol. 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.

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.

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.

yhfp putative quinone oxidoreductases (QOR). 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.

I, typified by liver dehydrogenase, is an evolving

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

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

Glutathione-dependent formaldehyde dehydrogenases (FDHs)
are members of the zinc-dependent/medium chain alcohol
dehydrogenase family. Formaldehyde dehydrogenase (FDH)
is a member of the zinc-dependent/medium chain alcohol
dehydrogenase family. FDH converts formaldehyde and NAD
to formate and NADH. 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.
These tetrameric FDHs have a catalytic zinc that resides
between the catalytic and NAD(H)binding domains and a
structural zinc in a lobe of the catalytic domain. The
medium chain alcohol dehydrogenase family (MDR) has a
NAD(P)(H)-binding domain in a Rossmann fold of a
beta-alpha form. The N-terminal region typically has an

aldehydes or ketones. This group contains members
identified as zinc dependent alcohol dehydrogenases
(ADH), and class III ADG (aka formaldehyde

converts ethanol and NAD+ to acetaldehyde and NADH,

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.
Class III ADH are also know as glutathione-dependent
formaldehyde dehydrogenase (FDH), which convert
aldehydes to the corresponding carboxylic acid and
alcohol. 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.

contains the hypothetical TM0436 alcohol dehydrogenase
from Thermotoga maritima, proteins annotated as
5-exo-alcohol dehydrogenase, and other members of the

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.

family. Unlike typical FDH, Pseudomonas putida
aldehyde-dismutating FDH (PFDH) is

MDH family uses NAD(H) as a cofactor in the

dehydrogenases. NAD(P)(H)-dependent oxidoreductases are
the major enzymes in the interconversion of alcohols and
aldehydes or ketones. This group includes alcohol
dehydrogenases corresponding to mammalian classes I, II,
IV. 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 (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.

putative quinone oxidoreductases (QOR). 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

polarizing it, and leading to the reverse reaction.

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.

(MDR)/zinc-dependent alcohol dehydrogenase-like family.
This group contains members identified as related to
zinc-dependent alcohol dehydrogenase and other members
of the MDR family, including threonine dehydrogenase.
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.

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-Rossman 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.

>gnl|CDD|133125 cd06594, GH31_glucosidase_YihQ, YihQ is a bacterial
alpha-glucosidase with a conserved glycosyl hydrolase
family 31 (GH31) domain that catalyzes the release of an
alpha-glucosyl residue from the non-reducing end of
alpha-glucoside substrates such as alpha-glucosyl
fluoride. Orthologs of YihQ that have not yet been
functionally characterized are present in plants and
fungi. YihQ has sequence similarity to other GH31
enzymes such as CtsZ, a 6-alpha-glucosyltransferase from
Bacillus globisporus, and YicI, an alpha-xylosidase from
Echerichia coli. In bacteria, YihQ (along with YihO) is
important for bacterial O-antigen capsule assembly and
translocation.

3,4-dihydroxyphenylacetate 2,3-dioxygenase (HPCD);
belongs to the type I class II family of extradiol
dioxygenases. This subfamily contains the N-terminal,
non-catalytic, domain of HPCD. HPCD catalyses the second
step in the degradation of 4-hydroxyphenylacetate to
succinate and pyruvate. The aromatic ring of
4-hydroxyphenylacetate is opened by this dioxygenase to
yield the 3,4-diol product,
2-hydroxy-5-carboxymethylmuconate semialdehyde. HPCD is
a homotetramer and each monomer contains two
structurally homologous barrel-shaped domains at the N-
and C-terminus. The active-site metal is located in the
C-terminal barrel and plays an essential role in the
catalytic mechanism. Most extradiol dioxygenases contain
Fe(II) in their active site, but HPCD can be activated
by either Mn(II) or Fe(II). These enzymes belong to the
type I class II family of extradiol dioxygenases. The
class III 3,4-dihydroxyphenylacetate 2,3-dioxygenases
belong to a different superfamily.
