>gnl|CDD|239303 cd03005, PDI_a_ERp46, PDIa family, endoplasmic reticulum protein 46
(ERp46) subfamily; ERp46 is an ER-resident protein
containing three redox active TRX domains. Yeast
complementation studies show that ERp46 can substitute
for protein disulfide isomerase (PDI) function in vivo.
It has been detected in many tissues, however,
transcript and protein levels do not correlate in all
tissues, suggesting regulation at a posttranscriptional
level. An identical protein, named endoPDI, has been
identified as an endothelial PDI that is highly
expressed in the endothelium of tumors and hypoxic
lesions. It has a protective effect on cells exposed to
hypoxia.

>gnl|CDD|239259 cd02961, PDI_a_family, Protein Disulfide Isomerase (PDIa) family,
redox active TRX domains; composed of eukaryotic
proteins involved in oxidative protein folding in the
endoplasmic reticulum (ER) by acting as catalysts and
folding assistants. Members of this family include PDI
and PDI-related proteins like ERp72, ERp57 (or ERp60),
ERp44, P5, PDIR, ERp46 and the transmembrane PDIs. PDI,
ERp57, ERp72, P5, PDIR and ERp46 are all oxidases,
catalyzing the formation of disulfide bonds of newly
synthesized polypeptides in the ER. They also exhibit
reductase activity in acting as isomerases to correct
any non-native disulfide bonds, as well as chaperone
activity to prevent protein aggregation and facilitate
the folding of newly synthesized proteins. These
proteins usually contain multiple copies of a redox
active TRX (a) domain containing a CXXC motif, and may
also contain one or more redox inactive TRX-like (b)
domains. Only one a domain is required for the oxidase
function but multiple copies are necessary for the
isomerase function. The different types of PDIs may show
different substrate specificities and tissue-specific
expression, or may be induced by stress. PDIs are in
their reduced form at steady state and are oxidized to
the active form by Ero1, which is localized in the ER
through ERp44. Some members of this family also contain
a DnaJ domain in addition to the redox active a domains;
examples are ERdj5 and Pfj2. Also included in the family
is the redox inactive N-terminal TRX-like domain of
ERp29.

>gnl|CDD|239296 cd02998, PDI_a_ERp38, PDIa family, endoplasmic reticulum protein 38
(ERp38) subfamily; composed of proteins similar to the
P5-like protein first isolated from alfalfa, which
contains two redox active TRX (a) domains at the
N-terminus, like human P5, and a C-terminal domain with
homology to the C-terminal domain of ERp29, unlike human
P5. The cDNA clone of this protein (named G1) was
isolated from an alfalfa cDNA library by screening with
human protein disulfide isomerase (PDI) cDNA. The G1
protein is constitutively expressed in all major organs
of the plant and its expression is induced by treatment
with tunicamycin, indicating that it may be a
glucose-regulated protein. The G1 homolog in the
eukaryotic social amoeba Dictyostelium discoideum is
also described as a P5-like protein, which is located in
the endoplasmic reticulum (ER) despite the absence of an
ER-retrieval signal. G1 homologs from Aspergillus niger
and Neurospora crassa have also been characterized, and
are named TIGA and ERp38, respectively. Also included in
the alignment is an atypical PDI from Leishmania
donovani containing a single a domain, and the
C-terminal a domain of a P5-like protein from Entamoeba
histolytica.

subfamily; composed of the C-terminal redox active a'
domains of PDI, ERp72, ERp57 (or ERp60) and EFP1. PDI,
ERp72 and ERp57 are endoplasmic reticulum (ER)-resident
eukaryotic proteins involved in oxidative protein
folding. They are oxidases, catalyzing the formation of
disulfide bonds of newly synthesized polypeptides in the
ER. They also exhibit reductase activity in acting as
isomerases to correct any non-native disulfide bonds, as
well as chaperone activity to prevent protein
aggregation and facilitate the folding of newly
synthesized proteins. PDI and ERp57 have the abb'a'
domain structure (where a and a' are redox active TRX
domains while b and b' are redox inactive TRX-like
domains). PDI also contains an acidic region (c domain)
after the a' domain that is absent in ERp57. ERp72 has
an additional a domain at the N-terminus (a"abb'a'
domain structure). ERp57 interacts with the lectin
chaperones, calnexin and calreticulin, and specifically
promotes the oxidative folding of glycoproteins, while
PDI shows a wider substrate specificity. ERp72
associates with several ER chaperones and folding
factors to form complexes in the ER that bind nascent
proteins. EFP1 is a binding partner protein of thyroid
oxidase, which is responsible for the generation of
hydrogen peroxide, a crucial substrate of
thyroperoxidase, which functions to iodinate
thyroglobulin and synthesize thyroid hormones.

TRX-like (b) domain. Similar to PDI, it is involved in
oxidative protein folding in the endoplasmic reticulum
(ER) through its isomerase and chaperone activities.
These activities are lower compared to PDI, probably due
to PDIR acting only on a subset of proteins. PDIR is
preferentially expressed in cells actively secreting
proteins and its expression is induced by stress.
Similar to PDI, the isomerase and chaperone activities
of PDIR are independent; CXXC mutants lacking isomerase
activity retain chaperone activity.

>gnl|CDD|239245 cd02947, TRX_family, TRX family; composed of two groups: Group I,
which includes proteins that exclusively encode a TRX
domain; and Group II, which are composed of fusion
proteins of TRX and additional domains. Group I TRX is a
small ancient protein that alter the redox state of
target proteins via the reversible oxidation of an
active site dithiol, present in a CXXC motif, partially
exposed at the protein's surface. TRX reduces protein
disulfide bonds, resulting in a disulfide bond at its
active site. Oxidized TRX is converted to the active
form by TRX reductase, using reducing equivalents
derived from either NADPH or ferredoxins. By altering
their redox state, TRX regulates the functions of at
least 30 target proteins, some of which are enzymes and
transcription factors. It also plays an important role
in the defense against oxidative stress by directly
reducing hydrogen peroxide and certain radicals, and by
serving as a reductant for peroxiredoxins. At least two
major types of functional TRXs have been reported in
most organisms; in eukaryotes, they are located in the
cytoplasm and the mitochondria. Higher plants contain
more types (at least 20 TRX genes have been detected in
the genome of Arabidopsis thaliana), two of which (types
f amd m) are located in the same compartment, the
chloroplast. Also included in the alignment are TRX-like
domains which show sequence homology to TRX but do not
contain the redox active CXXC motif. Group II proteins,
in addition to either a redox active TRX or a TRX-like
domain, also contain additional domains, which may or
may not possess homology to known proteins.

the N-terminal redox active TRX domain is present in the

oriented towards the cytoplasm. It is expressed in many
cell types and its active site motif (CPAC) is unique.
In vitro, TMX reduces interchain disulfides of insulin
and renatures inactive RNase containing incorrect
disulfide bonds. The C. elegans homolog, DPY-11, is
expressed only in the hypodermis and resides in the
cytoplasm. It is required for body and sensory organ
morphogeneis. Another uncharacterized TRX-related

adenine dinucleotide (FAD)-binding domain homologous to

is accompanied by the reduction of oxygen to hydrogen
peroxide. QSOX is localized in high concentrations in
cells with heavy secretory load and prefers peptides and
proteins as substrates, not monothiols like glutathione.
Inside the cell, QSOX is found in the endoplasmic
reticulum and Golgi. The flow of reducing equivalents in
a QSOX-catalyzed reaction goes from the dithiol
substrate -> dithiol of the QSOX TRX domain -> dithiols
of the QSOX ERV1p domain -> FAD -> oxygen.

retention. It contains an N-terminal TRX domain, similar
to that of PDIa, with a CXFS motif followed by two redox
inactive TRX-like domains, homologous to the b and b'
domains of PDI. The CXFS motif in the N-terminal domain
allows ERp44 to form stable reversible mixed disulfides
with its substrates. Through this activity, ERp44
mediates the ER localization of Ero1alpha, a protein
that oxidizes protein disulfide isomerases into their
active form. ERp44 also prevents the secretion of
unassembled cargo protein with unpaired cysteines. It
also modulates the activity of inositol
1,4,5-triphosphate type I receptor (IP3R1), an
intracellular channel protein that mediates calcium
release from the ER to the cytosol.

reductase subfamily; composed of plant-type APS
reductases containing a C-terminal redox active TRX
domain and an N-terminal reductase domain which is part
of a superfamily that includes N type ATP PPases. APS
reductase catalyzes the reduction of activated sulfate
to sulfite, a key step in the biosynthesis of
sulfur-containing metabolites. Sulfate is first
activated by ATP sulfurylase, forming APS, which can be
phosphorylated to 3'-phosphoadenosine-5'-phosphosulfate
(PAPS). Depending on the organism, either APS or PAPS
can be used for sulfate reduction. Prokaryotes and fungi
use PAPS, whereas plants use both APS and PAPS. Since
plant-type APS reductase uses glutathione (GSH) as its
electron donor, the C-terminal domain may function like
glutaredoxin, a GSH-dependent member of the TRX
superfamily. The flow of reducing equivalents goes from
GSH -> C-terminal TRX domain -> N-terminal reductase
domain -> APS. Plant-type APS reductase shows no
homology to that of dissimilatory sulfate-reducing
bacteria, which is an iron-sulfur flavoenzyme. Also
included in the alignment is EYE2 from Chlamydomonas
reinhardtii, a protein required for eyespot assembly.

subfamily, N-terminal TRX-fold domain; Calsequestrin is
the major calcium storage protein in the sarcoplasmic
reticulum (SR) of skeletal and cardiac muscle. It stores
calcium ions in sufficient quantities (up to 20 mM) to
allow repetitive contractions and is essential to
maintain movement, respiration and heart beat. A
missense mutation in human cardiac calsequestrin is
associated with catecholamine-induced polymorphic
ventricular tachycardia (CPVT), a rare disease
characterized by seizures or sudden death in response to
physiologic or emotional stress. Calsequestrin is a
highly acidic protein with up to 50 calcium binding
sites formed simply by the clustering of two or more
acidic residues. The monomer contains three redox
inactive TRX-fold domains. Calsequestrin is condensed as
a linear polymer in the SR lumen and is
membrane-anchored through binding with intra-membrane
proteins triadin, junctin and ryanodine receptor (RyR)
Ca2+ release channel. In addition to its role as a
calcium ion buffer, calsequestrin also regulates the
activity of the RyR channel, coordinating the release of
calcium ions from the SR with the loading of the calcium
store. The N-terminal TRX-fold domain (or domain I)
mediates front-to-front dimer interaction, an important
feature in the formation of calsequestrin polymers.

assimilation of inorganic sulfate, is closely related to
the thioredoxin-dependent PAPS reductase of Bacteria
(CysH) and Saccharomyces cerevisiae. However, it has its
own C-terminal thioredoxin-like domain and is not
thioredoxin-dependent. Also, it has a substrate
preference for 5'-adenylylsulfate (APS) over
3'-phosphoadenylylsulfate (PAPS) so the pathway does not
require an APS kinase (CysC) to convert APS to PAPS.
Arabidopsis thaliana appears to have three isozymes, all
able to complement E. coli CysH mutants (even in
backgrounds lacking thioredoxin or APS kinase) but
likely localized to different compartments in
Arabidopsis [Central intermediary metabolism, Sulfur

throughout the cilia and flagella. The human homolog is
the sperm-specific Sptrx-2, presumed to be a component
of the human sperm axoneme architecture. Included in
this group is another human protein, TRX-like protein 2,
a smaller fusion protein containing one TRX and one NDPK
domain, which is also associated with microtubular
structures. The other members of this group are
hypothetical insect proteins containing a TRX domain and
outer arm dynein light chains (14 and 16kDa) of
Chlamydomonas reinhardtii. Using standard assays, the
fusion proteins have shown no TRX enzymatic activity.

(ADH) and class III ADG (AKA formaldehyde
dehydrogenase). NAD(P)(H)-dependent oxidoreductases are
the major enzymes in the interconversion of alcohols and
aldehydes or ketones. This group contains members
identified as zinc dependent alcohol dehydrogenases
(ADH), and class III ADG (aka formaldehyde
dehydrogenase, FDH). 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. 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 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.

Phd-like proteins (PhLP), characterized as cytosolic
regulators of G protein functions. Phd and PhLPs
specifically bind G protein betagamma (Gbg)-subunits
with high affinity, resulting in the solubilization of
Gbg from the plasma membrane and impeding G
protein-mediated signal transduction by inhibiting the
formation of a functional G protein trimer (G protein
alphabetagamma). Phd also inhibits the GTPase activity
of G protein alpha. Phd can be phosphorylated by protein
kinase A and G protein-coupled receptor kinase 2,
leading to its inactivation. Phd was originally isolated
from the retina, where it is highly expressed and has
been implicated to play an important role in light
adaptation. It is also found in the pineal gland, liver,
spleen, striated muscle and the brain. The C-terminal
domain of Phd adopts a thioredoxin fold, but it does not
contain a CXXC motif. Phd interacts with G protein beta
mostly through the N-terminal helical domain. Also
included in this family is a PhLP characterized as a
viral inhibitor of apoptosis (IAP)-associated factor,
named VIAF, that functions in caspase activation during
apoptosis.

methylamine as a sole carbon source and a nitrogen
source. mauD is an essential accessory protein for the
biosynthesis of methylamine dehydrogenase (MADH), the
enzyme that catalyzes the oxidation of methylamine and
other primary amines. MADH possesses an alpha2beta2
subunit structure; the alpha subunit is also referred to
as the large subunit. Each beta (small) subunit contains
a tryptophan tryptophylquinone (TTQ) prosthetic group.
Accessory proteins are essential for the proper
transport of MADH to the periplasm, TTQ synthesis and
the formation of several structural disulfide bonds.
Bacterial mutants containing an insertion on the mauD
gene were unable to grow on methylamine as a sole carbon
source, were found to lack the MADH small subunit and
had decreased amounts of the MADH large subunit.

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

of 2 structurally similar halves, each of which contacts

monomeric thiol disulfide oxidoreductase protein
containing a redox active CXXC motif imbedded in a TRX
fold. It is involved in the oxidative protein folding
pathway in prokaryotes, and is the strongest thiol
oxidant known, due to the unusual stability of the
thiolate anion form of the first cysteine in the CXXC
motif. The highly unstable oxidized form of DsbA
directly donates disulfide bonds to reduced proteins
secreted into the bacterial periplasm. This rapid and
unidirectional process helps to catalyze the folding of
newly-synthesized polypeptides. To regain catalytic
activity, reduced DsbA is then reoxidized by the
membrane protein DsbB, which generates its disulfides
from oxidized quinones, which in turn are reoxidized by
the electron transport chain.

and nucleoredoxin (NRX) subfamily; TryX and NRX are
thioredoxin (TRX)-like protein disulfide oxidoreductases
that alter the redox state of target proteins via the
reversible oxidation of an active center CXXC motif.
TryX is involved in the regulation of oxidative stress
in parasitic trypanosomatids by reducing TryX
peroxidase, which in turn catalyzes the reduction of
hydrogen peroxide and organic hydroperoxides. TryX
derives reducing equivalents from reduced trypanothione,
a polyamine peptide conjugate unique to trypanosomatids,
which is regenerated by the NADPH-dependent flavoprotein
trypanothione reductase. Vertebrate NRX is a 400-amino
acid nuclear protein with one redox active TRX domain
containing a CPPC active site motif followed by one
redox inactive TRX-like domain. Mouse NRX transcripts
are expressed in all adult tissues but is restricted to
the nervous system and limb buds in embryos. Plant NRX,
longer than the vertebrate NRX by about 100-200 amino
acids, is a nuclear protein containing a redox inactive
TRX-like domain between two redox active TRX domains.
Both vertebrate and plant NRXs show thiol oxidoreductase
activity in vitro. Their localization in the nucleus
suggests a role in the redox regulation of nuclear
proteins such as transcription factors.
