>gnl|CDD|238319 cd00570, GST_N_family, Glutathione S-transferase (GST) family,
N-terminal domain; a large, diverse group of cytosolic
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.

the CXXC motif of glutaredoxins, which is a redox
active residue capable of reducing GSH mixed disulfides
in a monothiol mechanism. Polymorphisms of the class
Omega GST genes may be associated with the development
of some types of cancer and the age-at-onset of both
Alzheimer's and Parkinson's diseases.

undergone extensive gene duplication. The Arabidopsis
and Oryza genomes contain 28 and 40 Tau GSTs,
respectively. They are primarily responsible for
herbicide detoxification together with class Phi GSTs,
showing class specificity in substrate preference. Tau
enzymes are highly efficient in detoxifying
diphenylether and aryloxyphenoxypropionate herbicides.
In addition, Tau GSTs play important roles in
intracellular signalling, biosynthesis of anthocyanin,
responses to soil stresses and responses to auxin and
cytokinin hormones.

in a wide variety of functions including regulated
secretion, cell division and apoptosis. They can exist
in both water-soluble and membrane-bound states, and
are found in various vesicles and membranes.
Biochemical studies of the C. elegans homolog, EXC-4,
show that the membrane localization domain is present
in the N-terminal part of the protein. The structure of
soluble human CLIC1 reveals that it is monomeric and it
adopts a fold similar to GSTs, containing an N-terminal
domain with a TRX fold and a C-terminal alpha helical
domain. Upon oxidation, the N-terminal domain of CLIC1
undergoes a structural change to form a non-covalent
dimer stabilized by the formation of an intramolecular
disulfide bond between two cysteines that are far apart
in the reduced form. The CLIC1 dimer bears no
similarity to GST dimers. The redox-controlled
structural rearrangement exposes a large hydrophobic
surface, which is masked by dimerization in vitro. In
vivo, this surface may represent the docking interface
of CLIC1 in its membrane-bound state. The two cysteines
in CLIC1 that form the disulfide bond in oxidizing
conditions are essential for dimerization and chloride
channel activity, however, in other subfamily members,
the second cysteine is not conserved.

unique to their group, such as catalyzing thiolysis,

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.

subfamily; composed of the Escherichia coli YfcG and

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. GSTs also show GSH
peroxidase activity and are involved in the synthesis of
prostaglandins and leukotrienes. The GST active site is
located in a cleft between the N- and C-terminal
domains. GSH binds to the N-terminal domain while the
hydrophobic substrate occupies a pocket in the
C-terminal domain. YfcG is one of nine GST homologs in
Escherichia coli. It is expressed predominantly during
the late stationary phase where the predominant form of
GSH is glutathionylspermidine (GspSH), suggesting that
YfcG might interact with GspSH. It has very low or no
GSH transferase or peroxidase activity, but displays a
unique disulfide bond reductase activity that is
comparable to thioredoxins (TRXs) and glutaredoxins
(GRXs). However, unlike TRXs and GRXs, YfcG does not
contain a redox active cysteine residue and may use a
bound thiol disulfide couple such as 2GSH/GSSG for
activity. The crystal structure of YcfG reveals a bound
GSSG molecule in its active site. The actual
physiological substrates for YfcG are yet to be
identified.

is part of the eukaryotic translation elongation
factor-1 (EF1) complex which plays a central role in
the elongation cycle during protein biosynthesis. EF1
consists of two functionally distinct units, EF1A and
EF1B. EF1A catalyzes the GTP-dependent binding of
aminoacyl-tRNA to the ribosomal A site concomitant with
the hydrolysis of GTP. The resulting inactive EF1A:GDP
complex is recycled to the active GTP form by the

composed of at least two subunits, alpha and gamma.
Metazoan EFB1 contain a third subunit, beta. The EF1B
gamma subunit contains a GST fold consisting of an

helical domain. The GST-like domain of EF1Bgamma is
believed to mediate the dimerization of the EF1
complex, which in yeast is a dimer of the heterotrimer
EF1A:EF1Balpha:EF1Bgamma. In addition to its role in
protein biosynthesis, EF1Bgamma may also display other
functions. The recombinant rice protein has been shown
to possess GSH conjugating activity. The yeast
EF1Bgamma binds membranes in a calcium dependent manner
and is also part of a complex that binds to the msrA

act as a hydrogen donor for RNR-Ib. It has been
suggested that the NrdHEF system may be the oldest RNR

composed of the Saccharomyces cerevisiae Ure2p and
related GSTs. Ure2p is a regulator for nitrogen
catabolism in yeast. It represses the expression of
several gene products involved in the use of poor
nitrogen sources when rich sources are available. A
transmissible conformational change of Ure2p results in
a prion called [Ure3], an inactive, self-propagating
and infectious amyloid. Ure2p displays a GST fold
containing 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. The
N-terminal TRX-fold domain is sufficient to induce the
[Ure3] phenotype and is also called the prion domain of
Ure2p. In addition to its role in nitrogen regulation,
Ure2p confers protection to cells against heavy metal
ion and oxidant toxicity, and shows glutathione (GSH)
peroxidase activity. Characterized GSTs in this
subfamily include Aspergillus fumigatus GSTs 1 and 2,
and Schizosaccharomyces pombe GST-I. GSTs are cytosolic
dimeric proteins involved in cellular detoxification by
catalyzing the conjugation of GSH with a wide range of
endogenous and xenobiotic alkylating agents, including
carcinogens, therapeutic drugs, environmental toxins
and products of oxidative stress. GSTs also show GSH
peroxidase activity and are involved in the synthesis
of prostaglandins and leukotrienes.

reactive oxygen species. Because AsA is the major
reductant in plants, DHAR serves to regulate their redox

of DHAR activity is plastidic, acting to reduce the
large amounts of ascorbate oxidized during hydrogen

1-like proteins. Glutathione S-transferase (GST)
C-terminal domain family, Ganglioside-induced
differentiation-associated protein 1 (GDAP1)-like
subfamily; GDAP1 was originally identified as a highly
expressed gene at the differentiated stage of GD3
synthase-transfected cells. More recently, mutations in
GDAP1 have been reported to cause both axonal and
demyelinating autosomal-recessive Charcot-Marie-Tooth
(CMT) type 4A neuropathy. CMT is characterized by slow
and progressive weakness and atrophy of muscles.
Sequence analysis of GDAP1 shows similarities and
differences with GSTs; it appears to contain both
N-terminal thioredoxin-fold and C-terminal alpha helical
domains of GSTs, however, it also contains additional
C-terminal transmembrane domains unlike GSTs. GDAP1 is
mainly expressed in neuronal cells and is localized in
the mitochondria through its transmembrane domains. It
does not exhibit GST activity using standard substrates.

Glutathione S-transferases. Glutathione S-transferase
(GST) C-terminal domain family, Class Zeta subfamily;
GSTs are cytosolic 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. The GST fold contains an N-terminal
thioredoxin-fold domain and a C-terminal alpha helical
domain, with an active site located in a cleft between
the two domains. GSH binds to the N-terminal domain
while the hydrophobic substrate occupies a pocket in the
C-terminal domain. Class Zeta GSTs, also known as
maleylacetoacetate (MAA) isomerases, catalyze the
isomerization of MAA to fumarylacetoacetate, the
penultimate step in tyrosine/phenylalanine catabolism,
using GSH as a cofactor. They show little
GSH-conjugating activity towards traditional GST
substrates, but display modest GSH peroxidase activity.
They are also implicated in the detoxification of the
carcinogen dichloroacetic acid by catalyzing its
dechlorination to glyoxylic acid.
