>gnl|CDD|200072 TIGR01068, thioredoxin, thioredoxin. Several proteins, such as
protein disulfide isomerase, have two or more copies of
a domain closely related to thioredoxin. This model is
designed to recognize authentic thioredoxin, a small
protein that should be hit exactly once by This model.
Any protein that hits once with a score greater than the
second (per domain) trusted cutoff may be taken as
thioredoxin [Energy metabolism, Electron transport].

>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.

>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.

ERdj5, also known as JPDI and macrothioredoxin, is a
protein containing an N-terminal DnaJ domain and four
redox active TRX domains. This subfamily is comprised of
the first TRX domain of ERdj5 located after the DnaJ
domain at the N-terminal half of the protein. ERdj5 is a
ubiquitous protein localized in the endoplasmic
reticulum (ER) and is abundant in secretory cells. It's
transcription is induced during ER 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 degradation
and protein translocation.

TryX 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.

proteins which contain one redox active TRX domain

characterized as intermediate chains (ICs) of axonemal
outer arm dynein. Dyneins are molecular motors that
generate force against microtubules to produce cellular

to size: dynein heavy, intermediate and light chains.
Axonemal dyneins form two structures, the inner and

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

with high affinity, resulting in the solubilization of
Gbg from the plasma membrane. This impedes the formation
of a functional G protein trimer (G protein
alphabetagamma), thereby inhibiting G protein-mediated
signal transduction. 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

C-terminal domain of Phd adopts a thioredoxin fold, but
it does not contain a CXXC motif. Phd interacts with G

>gnl|CDD|239271 cd02973, TRX_GRX_like, Thioredoxin (TRX)-Glutaredoxin (GRX)-like
family; composed of archaeal and bacterial proteins that
show similarity to both TRX and GRX, including the
C-terminal TRX-fold subdomain of Pyrococcus furiosus
protein disulfide oxidoreductase (PfPDO). All members
contain a redox-active CXXC motif and may function as
PDOs. The archaeal proteins Mj0307 and Mt807 show
structures more similar to GRX, but activities more
similar to TRX. Some members of the family are similar
to PfPDO in that they contain a second CXXC motif
located in a second TRX-fold subdomain at the
N-terminus; the superimposable N- and C-terminal TRX
subdomains form a compact structure. PfPDO is postulated
to be the archaeal counterpart of bacterial DsbA and
eukaryotic protein disulfide isomerase (PDI). The
C-terminal CXXC motif of PfPDO is required for its
oxidase, reductase and isomerase activities. Also
included in the family is the C-terminal TRX-fold
subdomain of the N-terminal domain (NTD) of bacterial
AhpF, which has a similar fold as PfPDO with two
TRX-fold subdomains but without the second CXXC motif.

>gnl|CDD|232970 TIGR00424, APS_reduc, 5'-adenylylsulfate reductase,
thioredoxin-independent. This enzyme, involved in the
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
metabolism].

>gnl|CDD|100111 cd05833, Ribosomal_P2, Ribosomal protein P2. This subfamily
represents the eukaryotic large ribosomal protein P2.
Eukaryotic P1 and P2 are functionally equivalent to the
bacterial protein L7/L12, but are not homologous to
L7/L12. P2 is located in the L12 stalk, with proteins
P1, P0, L11, and 28S rRNA. P1 and P2 are the only
proteins in the ribosome to occur as multimers, always
appearing as sets of heterodimers. Recent data indicate
that eukaryotes have four copies (two heterodimers),
while most archaeal species contain six copies of L12p
(three homodimers). Bacteria may have four or six
copies of L7/L12 (two or three homodimers) depending on
the species. Experiments using S. cerevisiae P1 and P2
indicate that P1 proteins are positioned more
internally with limited reactivity in the C-terminal
domains, while P2 proteins seem to be more externally
located and are more likely to interact with other
cellular components. In lower eukaryotes, P1 and P2 are
further subdivided into P1A, P1B, P2A, and P2B, which
form P1A/P2B and P1B/P2A heterodimers. Some plants have
a third P-protein, called P3, which is not homologous
to P1 and P2. In humans, P1 and P2 are strongly
autoimmunogenic. They play a significant role in the
etiology and pathogenesis of systemic lupus erythema
(SLE). In addition, the ribosome-inactivating protein
trichosanthin (TCS) interacts with human P0, P1, and
P2, with its primary binding site in the C-terminal
region of P2. TCS inactivates the ribosome by
depurinating a specific adenine in the sarcin-ricin
loop of 28S rRNA.

bacterial sequences found in this family are similar to
the N-terminal region of the TraG protein. This is a
membrane-spanning protein, with three predicted
transmembrane segments and two periplasmic regions. TraG
protein is known to be essential for DNA transfer in the
process of conjugation, with the N-terminal portion
being required for F pilus assembly. The protein is
thought to interact with the periplasmic domain of TraN
to stabilise mating-cell interactions.
