>gnl|CDD|239294 cd02996, PDI_a_ERp44, PDIa family, endoplasmic reticulum protein 44
(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.

>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.

eukaryotic proteins similar to human P5, a PDI-related
protein with a domain structure of aa'b (where a and a'
are redox active TRX domains and b is a redox inactive
TRX-like domain). Like PDI, P5 is located in the
endoplasmic reticulum (ER) and displays both isomerase
and chaperone activities, which are independent of each
other. Compared to PDI, the isomerase and chaperone
activities of P5 are lower. The first cysteine in the
CXXC motif of both redox active domains in P5 is
necessary for isomerase activity. The P5 gene was first
isolated as an amplified gene from a
hydroxyurea-resistant hamster cell line. The zebrafish
P5 homolog has been implicated to play a critical role
in establishing left/right asymmetries in the embryonic
midline. Some members of this subfamily are P5-like
proteins containing only one redox active TRX domain.

stress. It interacts with BiP through its DnaJ domain in
an ATP-dependent manner. BiP, an ER-resident member of
the Hsp70 chaperone family, functions in ER-associated

substrate -> dithiol of the QSOX TRX domain -> dithiols
of the QSOX ERV1p domain -> FAD -> oxygen.

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.

>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.

to the redox active TRX domains of protein disulfide

N-terminal TRX domain of EFP1, which contains a CXXS
sequence in place of the typical CXXC motif, similar to

redox active TRX domains. This subfamily is comprised of
the first TRX domain of ERdj5 located after the DnaJ

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.
