>gnl|CDD|233282 TIGR01130, ER_PDI_fam, protein disulfide isomerase, eukaryotic.
This model represents eukaryotic protein disulfide
isomerases retained in the endoplasmic reticulum (ER)
and closely related forms. Some members have been
assigned alternative or additional functions such as
prolyl 4-hydroxylase and
dolichyl-diphosphooligosaccharide-protein
glycotransferase. Members of this family have at least
two protein-disulfide domains, each similar to
thioredoxin but with the redox-active disulfide in the
motif PWCGHCK, and an ER retention signal at the extreme
C-terminus (KDEL, HDEL, and similar motifs).

subfamily, second redox inactive TRX-like domain b';
ERp72 and ER57 are involved in oxidative protein folding
in the ER, like PDI. They exhibit both disulfide oxidase
and reductase functions, by catalyzing the formation of
disulfide bonds of newly synthesized polypeptides and
acting as isomerases to correct any non-native disulfide
bonds. They also display chaperone activity to prevent
protein aggregation and facilitate the folding of newly
synthesized proteins. ERp57 contains two redox-active
TRX (a) domains and two redox inactive TRX-like (b)
domains. It shares the same domain arrangement of
abb'a' as PDI, but lacks the C-terminal acid-rich region
(c domain) that is present in PDI. ERp72 contains one
additional redox-active TRX (a) domain at the N-terminus
with a molecular structure of a"abb'a'. ERp57 interacts
with the lectin chaperones, calnexin and calreticulin,
and specifically promotes the oxidative folding of
glycoproteins. ERp72 associates with several ER
chaperones and folding factors to form complexes in the
ER that bind nascent proteins. The b' domain of ERp57 is
the primary binding site and is adapted for ER lectin
association. Similarly, the b' domain of ERp72 is likely
involved in substrate recognition.

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.

(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.

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.

other. Compared to PDI, the isomerase and chaperone
activities of P5 are lower. The first cysteine in the

redox inactive TRX-like domain b'; 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, calsequestrin and other PDI-related
proteins like ERp72, ERp57 (or ERp60), ERp44, P5 and
PDIR. PDI, ERp57, ERp72, P5 and PDIR 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 contain multiple copies of a redox active TRX
(a) domain containing a CXXC motif, and one or more
redox inactive TRX-like (b) domains. The molecular
structure of PDI is abb'a'. Also included in this family
is the PDI-related protein ERp27, which contains only
redox-inactive TRX-like (b and b') domains. The redox
inactive domains are implicated in substrate recognition
with the b' domain serving as the primary substrate
binding site. Only the b' domain is necessary for the
binding of small peptide substrates. In addition to the
b' domain, other domains are required for the binding of
larger polypeptide substrates. The b' domain is also
implicated in chaperone activity.

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.

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

(ERp44) subfamily; ERp44 is an ER-resident protein,
induced during stress, involved in thiol-mediated ER
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.

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,

>gnl|CDD|239270 cd02972, DsbA_family, DsbA family; consists of DsbA and DsbA-like
proteins, including DsbC, DsbG, glutathione (GSH)
S-transferase kappa (GSTK),
2-hydroxychromene-2-carboxylate (HCCA) isomerase, an
oxidoreductase (FrnE) presumed to be involved in
frenolicin biosynthesis, a 27-kDa outer membrane
protein, and similar proteins. Members of this family
contain a redox active CXXC motif (except GSTK and HCCA
isomerase) imbedded in a TRX fold, and an alpha helical
insert of about 75 residues (shorter in DsbC and DsbG)
relative to TRX. DsbA is involved in the oxidative
protein folding pathway in prokaryotes, catalyzing
disulfide bond formation of proteins secreted into the
bacterial periplasm. DsbC and DsbG function as protein
disulfide isomerases and chaperones to correct
non-native disulfide bonds formed by DsbA and prevent
aggregation of incorrectly folded proteins.

>gnl|CDD|239261 cd02963, TRX_DnaJ, TRX domain, DnaJ domain containing protein
family; composed of uncharacterized proteins of about
500-800 amino acids, containing an N-terminal DnaJ
domain followed by one redox active TRX domain. DnaJ is
a member of the 40 kDa heat-shock protein (Hsp40) family
of molecular chaperones, which regulate the activity of
Hsp70s. TRX is involved in the redox regulation of many
protein substrates through the reduction of disulfide
bonds. TRX has been implicated to catalyse the reduction
of Hsp33, a chaperone holdase that binds to unfolded
protein intermediates. The presence of DnaJ and TRX
domains in members of this family suggests that they
could be involved in a redox-regulated chaperone
network.
