>gnl|CDD|239329 cd03031, GRX_GRX_like, Glutaredoxin (GRX) family, GRX-like domain
containing protein subfamily; composed of
uncharacterized eukaryotic proteins containing a
GRX-like domain having only one conserved cysteine,
aligning to the C-terminal cysteine of the CXXC motif of
GRXs. This subfamily is predominantly composed of plant
proteins. GRX is a glutathione (GSH) dependent
reductase, catalyzing the disulfide reduction of target
proteins via a redox active CXXC motif using a similar
dithiol mechanism employed by TRXs. GRX has preference
for mixed GSH disulfide substrates, in which it uses a
monothiol mechanism where only the N-terminal cysteine
is required. Proteins containing only the C-terminal
cysteine are generally redox inactive.

>gnl|CDD|239017 cd02066, GRX_family, Glutaredoxin (GRX) family; composed of GRX,
approximately 10 kDa in size, and proteins containing a
GRX or GRX-like domain. GRX is a glutathione (GSH)
dependent reductase, catalyzing the disulfide reduction
of target proteins such as ribonucleotide reductase. It
contains a redox active CXXC motif in a TRX fold and
uses a similar dithiol mechanism employed by TRXs for
intramolecular disulfide bond reduction of protein
substrates. Unlike TRX, GRX has preference for mixed GSH
disulfide substrates, in which it uses a monothiol
mechanism where only the N-terminal cysteine is
required. The flow of reducing equivalents in the GRX
system goes from NADPH -> GSH reductase -> GSH -> GRX ->
protein substrates. By altering the redox state of
target proteins, GRX is involved in many cellular
functions including DNA synthesis, signal transduction
and the defense against oxidative stress. Different
classes are known including human GRX1 and GRX2, as well
as E. coli GRX1 and GRX3, which are members of this
family. E. coli GRX2, however, is a 24-kDa protein that
belongs to the GSH S-transferase (GST) family.

>gnl|CDD|233766 TIGR02181, GRX_bact, Glutaredoxin, GrxC family. Glutaredoxins are
thioltransferases (disulfide reductases) which utilize
glutathione and NADPH as cofactors. Oxidized glutathione
is regenerated by glutathione reductase. Together these
components compose the glutathione system. Glutaredoxins
utilize the CXXC motif common to thioredoxins and are
involved in multiple cellular processes including
protection from redox stress, reduction of critical
enzymes such as ribonucleotide reductase and the
generation of reduced sulfur for iron sulfur cluster
formation. Glutaredoxins are capable of reduction of
mixed disulfides of glutathione as well as the formation
of glutathione mixed disulfides. This family of
glutaredoxins includes the E. coli protein GrxC (Grx3)
which appears to have a secondary role in reducing
ribonucleotide reductase (in the absence of GrxA)
possibly indicating a role in the reduction of other
protein disulfides [Energy metabolism, Electron
transport].

cousin of TRX (PICOT)-like subfamily; composed of PICOT
and GRX-PICOT-like proteins. The non-PICOT members of
this family contain only the GRX-like domain, whereas
PICOT contains an N-terminal TRX-like domain followed by
one to three GRX-like domains. It is interesting to note
that PICOT from plants contain three repeats of the
GRX-like domain, metazoan proteins (except for insect)
have two repeats, while fungal sequences contain only
one copy of the domain. PICOT is a protein that
interacts with protein kinase C (PKC) theta, a calcium
independent PKC isoform selectively expressed in
skeletal muscle and T lymphocytes. PICOT inhibits the
activation of c-Jun N-terminal kinase and the
transcription factors, AP-1 and NF-kB, induced by PKC
theta or T-cell activating stimuli. Both GRX and TRX
domains of PICOT are required for its activity.
Characterized non-PICOT members of this family include
CXIP1, a CAX-interacting protein in Arabidopsis
thaliana, and PfGLP-1, a GRX-like protein from
Plasmodium falciparum.

subfamily; composed of hybrid proteins containing
peroxiredoxin (PRX) and GRX domains, which is found in
some pathogenic bacteria and cyanobacteria. PRXs are
thiol-specific antioxidant (TSA) proteins that confer a
protective antioxidant role in cells through their
peroxidase activity in which hydrogen peroxide,
peroxynitrate, and organic hydroperoxides are reduced
and detoxified using reducing equivalents derived from
either thioredoxin, glutathione, trypanothione and AhpF.
GRX is a glutathione (GSH) dependent reductase,
catalyzing the disulfide reduction of target proteins.
PRX-GRX hybrid proteins from Haemophilus influenza and
Neisseria meningitis exhibit GSH-dependent peroxidase
activity. The flow of reducing equivalents in the
catalytic cycle of the hybrid protein goes from NADPH ->
GSH reductase -> GSH -> GRX domain of hybrid -> PRX
domain of hybrid -> peroxide substrate.

thioltransferases (disulfide reductases) which utilize
glutathione and NADPH as cofactors. Oxidized glutathione
is regenerated by glutathione reductase. Together these
components compose the glutathione system. Glutaredoxins
utilize the CXXC motif common to thioredoxins and are
involved in multiple cellular processes including
protection from redox stress, reduction of critical
enzymes such as ribonucleotide reductase and the
generation of reduced sulfur for iron sulfur cluster
formation. Glutaredoxins are capable of reduction of
mixed disulfides of glutathione as well as the formation
of glutathione mixed disulfides. This model includes the
E. coli glyutaredoxin GrxA which appears to have primary
responsibility for the reduction of ribonucleotide
reductase.

dimeric proteins involved in cellular detoxification by
catalyzing the conjugation of glutathione (GSH) with a
wide range of endogenous and xenobiotic alkylating
agents, including carcinogens, therapeutic drugs,
environmental toxins and products of oxidative stress.
In addition, GSTs also show GSH peroxidase activity and
are involved in the synthesis of prostaglandins and
leukotrienes. This family, also referred to as soluble
GSTs, is the largest family of GSH transferases and is
only distantly related to the mitochondrial GSTs (GSTK
subfamily, a member of the DsbA family). Soluble GSTs
bear no structural similarity to microsomal GSTs (MAPEG
family) and display additional activities unique to
their group, such as catalyzing thiolysis, reduction
and isomerization of certain compounds. The GST fold
contains an N-terminal TRX-fold domain and a C-terminal
alpha helical domain, with an active site located in a
cleft between the two domains. Based on sequence
similarity, different classes of GSTs have been
identified, which display varying tissue distribution,
substrate specificities and additional specific
activities. In humans, GSTs display polymorphisms which
may influence individual susceptibility to diseases such
as cancer, arthritis, allergy and sclerosis. Some GST
family members with non-GST functions include
glutaredoxin 2, the CLIC subfamily of anion channels,
prion protein Ure2p, crystallins, metaxin 2 and
stringent starvation protein A.

monomeric protein with a conserved redox active CXXC
motif within a TRX fold, characterized by a glutaredoxin
(GRX)-like sequence and TRX-like activity profile. In
vitro, it displays protein disulfide reductase activity
that is dependent on TRX reductase, not glutathione
(GSH). It is part of the NrdHIEF operon, where NrdEF
codes for class Ib ribonucleotide reductase (RNR-Ib), an
efficient enzyme at low oxygen levels. Under these
conditions when GSH is mostly conjugated to spermidine,
NrdH can still function and act as a hydrogen donor for
RNR-Ib. It has been suggested that the NrdHEF system may
be the oldest RNR reducing system, capable of
functioning in a microaerophilic environment, where GSH
was not yet available. NrdH from Corynebacterium
ammoniagenes can form domain-swapped dimers, although it
is unknown if this happens in vivo. Domain-swapped
dimerization, which results in the blocking of the TRX
reductase binding site, could be a mechanism for
regulating the oxidation state of the protein.

therapeutic drugs, environmental toxins and products of
oxidative stress. The GST fold contains an N-terminal

by catalyzing the isomerization of PGH2. The functions
of PGD2 include the maintenance of body temperature,
inhibition of platelet aggregation, bronchoconstriction,
vasodilation and mediation of allergy and inflammation.
Other class Sigma members include the class II insect
GSTs, S-crystallins from cephalopods and 28-kDa GSTs
from parasitic flatworms. Drosophila GST2 is associated
with indirect flight muscle and exhibits preference for
catalyzing GSH conjugation to lipid peroxidation
products, indicating an anti-oxidant role. S-crystallin
constitutes the major lens protein in cephalopod eyes
and is responsible for lens transparency and proper
refractive index. The 28-kDa GST from Schistosoma is a
multifunctional enzyme, exhibiting GSH transferase, GSH
peroxidase and PGD2 synthase activities, and may play an
important role in host-parasite interactions. Also
members are novel GSTs from the fungus Cunninghamella

In response to oxidative stress, Spx can also activate
transcription, making it a general regulator that
exerts both positive and negative control over
transcription initiation. Spx has been shown to exert
redox-sensitive transcriptional control over genes like
trxA (TRX) and trxB (TRX reductase), genes that
function in thiol homeostasis. This redox-sensitive
activity is dependent on the presence of a CXXC motif,
present in some members of the Spx subfamily, that acts
as a thiol/disulfide switch. Spx has also been shown to
repress genes in a sulfate-dependent manner independent
of the presence of the CXXC motif.
