>gnl|CDD|198287 cd03177, GST_C_Delta_Epsilon, C-terminal, alpha helical domain of
Class Delta and Epsilon Glutathione S-transferases.
Glutathione S-transferase (GST) C-terminal domain
family, Class Delta and Epsilon 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. GSTs also show GSH peroxidase activity
and are involved in the synthesis of prostaglandins and
leukotrienes. 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. The class Delta and Epsilon subfamily
is made up primarily of insect GSTs, which play major
roles in insecticide resistance by facilitating
reductive dehydrochlorination of insecticides or
conjugating them with GSH to produce water-soluble
metabolites that are easily excreted. They are also
implicated in protection against cellular damage by
oxidative stress.

>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.

has experience extensive gene duplication. The
Arabidopsis and Oryza genomes contain 13 and 16 Phi
GSTs, respectively. They are primarily responsible for
herbicide detoxification together with class Tau GSTs,
showing class specificity in substrate preference. Phi
enzymes are highly reactive toward chloroacetanilide
and thiocarbamate herbicides. Some Phi GSTs have other
functions including transport of flavonoid pigments to
the vacuole, shoot regeneration and GSH peroxidase
activity.

>gnl|CDD|239348 cd03050, GST_N_Theta, GST_N family, Class Theta subfamily;
composed of eukaryotic class Theta GSTs and bacterial
dichloromethane (DCM) dehalogenase. 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 TRX-fold domain and
a C-terminal alpha helical domain, with an active site
located in a cleft between the two domains. Mammalian
class Theta GSTs show poor GSH conjugating activity
towards the standard substrates, CDNB and ethacrynic
acid, differentiating them from other mammalian GSTs.
GSTT1-1 shows similar cataytic activity as bacterial
DCM dehalogenase, catalyzing the GSH-dependent
hydrolytic dehalogenation of dihalomethanes. This is an
essential process in methylotrophic bacteria to enable
them to use chloromethane and DCM as sole carbon and
energy sources. The presence of polymorphisms in human
GSTT1-1 and its relationship to the onset of diseases
including cancer is subject of many studies. Human
GSTT2-2 exhibits a highly specific sulfatase activity,
catalyzing the cleavage of sulfate ions from aralkyl
sufate esters, but not from aryl or alkyl sulfate
esters.

>gnl|CDD|239346 cd03048, GST_N_Ure2p_like, GST_N family, Ure2p-like subfamily;
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

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).
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 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.
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, metaxins, stringent starvation protein A,
and aminoacyl-tRNA synthetases.

proteins. Glutathione S-transferase (GST) C-terminal
domain family, Ure2p-like subfamily; composed of the
Saccharomyces cerevisiae Ure2p, YfcG and YghU from
Escherichia coli, and related GST-like proteins. 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
thioredoxin-fold domain and a C-terminal alpha helical
domain. The N-terminal thioredoxin-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. YfcG and
YghU are two of the nine GST homologs in the genome of
Escherichia coli. They display very low or no GSH
transferase, but show very good disulfide bond
oxidoreductase activity. YghU also shows modest organic
hydroperoxide reductase activity. 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

be divided into the phi, tau, theta, zeta, and lambda

subunit of Elongation Factor 1B and similar proteins.
Glutathione S-transferase (GST) C-terminal domain
family, Gamma subunit of Elongation Factor 1B
(EF1Bgamma) subfamily; EF1Bgamma 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 guanine-nucleotide
exchange factor EF1B, a complex 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 N-terminal thioredoxin-fold domain
and a C-terminal alpha 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 to membranes in a
calcium dependent manner and is also part of a complex
that binds to the msrA (methionine sulfoxide reductase)
promoter suggesting a function in the regulation of its
gene expression. Also included in this subfamily is the
GST_C-like domain at the N-terminus of human valyl-tRNA
synthetase (ValRS) and its homologs. Metazoan ValRS
forms a stable complex with Elongation Factor-1H
(EF-1H), and together, they catalyze consecutive steps
in protein biosynthesis, tRNA aminoacylation and its
transfer to EF.

Multifunctional Protein (AIMP) 3 subfamily; AIMPs are
non-enzymatic cofactors that play critical roles in the
assembly and formation of a macromolecular multi-tRNA
synthetase protein complex that functions as a molecular
hub to coordinate protein synthesis. There are three
AIMPs, named AIMP1-3, which play diverse regulatory
roles. AIMP3, also called p18 or eukaryotic translation
elongation factor 1 epsilon-1 (EEF1E1), contains a
C-terminal domain with similarity to the C-terminal
alpha helical domain of GSTs. It specifically interacts
with methionyl-tRNA synthetase (MetRS) and is
translocated to the nucleus during DNA synthesis or in
response to DNA damage and oncogenic stress. In the
nucleus, it interacts with ATM and ATR, which are
upstream kinase regulators of p53. It appears to work
against DNA damage in cooperation with AIMP2, and
similar to AIMP2, AIMP3 is also a haploinsufficient
tumor suppressor. AIMP3 transgenic mice have shorter
lifespans than wild-type mice and they show
characteristics of progeria, suggesting that AIMP3 may
also be involved in cellular and organismal aging.

specificities. They are the most abundant GSTs in human
liver, skeletal muscle and brain, and are believed to
provide protection against diseases including cancer and
neurodegenerative disorders. Some isoenzymes have
additional specific functions. Human GST M1-1 acts as an
endogenous inhibitor of ASK1 (apoptosis
signal-regulating kinase 1) thereby suppressing
ASK1-mediated cell death. Human GSTM2-2 and 3-3 have
been identified as prostaglandin E2 synthases in the
brain and may play crucial roles in temperature and
sleep-wake regulation.

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. YghU is one of nine GST homologs in
the genome of Escherichia coli. It is similar to
Escherichia coli YfcG in that it has poor GSH
transferase activity towards typical substrates. It
shows modest reductase activity towards some organic
hydroperoxides. Like YfcG, YghU also shows good
disulfide bond oxidoreductase activity comparable to the
activities of glutaredoxins and thioredoxins. YghU 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 YghU reveals two GSH
molecules bound in its active site.

Gto2p, called ECM4, is involved in cell surface

Glutathione S-transferase (GST) C-terminal domain
family, Aminoacyl-tRNA synthetase (AaRS)-like subfamily;
This model characterizes the GST_C-like domain found in
the N-terminal region of some eukaryotic AaRSs, as well
as similar domains found in proteins involved in protein
synthesis including Aminoacyl tRNA synthetase
complex-Interacting Multifunctional Protein 2 (AIMP2),
AIMP3, and eukaryotic translation Elongation Factor 1
beta (eEF1b). AaRSs comprise a family of enzymes that
catalyze the coupling of amino acids with their matching
tRNAs. This involves the formation of an aminoacyl
adenylate using ATP, followed by the transfer of the
activated amino acid to the 3'-adenosine moiety of the
tRNA. AaRSs may also be involved in translational and
transcriptional regulation, as well as in tRNA
processing. AaRSs in this subfamily include GluRS from
lower eukaryotes, as well as GluProRS, MetRS, and CysRS
from higher eukaryotes. AIMPs are non-enzymatic
cofactors that play critical roles in the assembly and
formation of a macromolecular multi-tRNA synthetase
protein complex found in higher eukaryotes. The
GST_C-like domain is involved in protein-protein
interactions, mediating the formation of aaRS complexes
such as the MetRS-Arc1p-GluRS ternary complex in lower
eukaryotes and the multi-aaRS complex in higher
eukaryotes, that act as molecular hubs for protein
synthesis. AaRSs from prokaryotes, which are active as
dimers, do not contain this GST_C-like domain.

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
guanine-nucleotide exchange factor EF1B, a complex
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
N-terminal TRX-fold domain and a C-terminal alpha
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

subfamily; composed of proteins similar to Sphingomonas
paucimobilis beta etherase, LigE, a GST-like protein
that catalyzes the cleavage of the beta-aryl ether
linkages present in low-moleculer weight lignins using
GSH as the hydrogen donor. This reaction is an essential
step in the degradation of lignin, a complex phenolic
polymer that is the most abundant aromatic material in
the biosphere. The beta etherase activity of LigE is
enantioselective and it complements the activity of the
other GST family beta etherase, LigF.

BtuR/CobO/CobP. This family consists of the BtuR, CobO,
CobP proteins all of which are Cob(I)alamin (vitamin
B12) adenosyltransferase, which is involved in cobalamin
(vitamin B12) biosynthesis. This enzyme is a homodimer,
which catalyzes the adenosylation reaction: ATP +
cob(I)alamin + H2O <=> phosphate + diphosphate +
adenosylcobalamin.

>gnl|CDD|198327 cd10294, GST_C_ValRS_N, Glutathione S-transferase C-terminal-like,
alpha helical domain of vertebrate Valyl-tRNA
synthetase. Glutathione S-transferase (GST) C-terminal
domain family, Valyl-tRNA synthetase (ValRS) subfamily;
This model characterizes the GST_C-like domain found in
the N-terminal region of human ValRS and its homologs
from other vertebrates such as frog and zebrafish.
Aminoacyl-tRNA synthetases (aaRSs) comprise a family of
enzymes that catalyze the coupling of amino acids with
their matching tRNAs. This involves the formation of an
aminoacyl adenylate using ATP, followed by the transfer
of the activated amino acid to the 3'-adenosine moiety
of the tRNA. AaRSs may also be involved in translational
and transcriptional regulation, as well as in tRNA
processing. They typically form large stable complexes
with other proteins. ValRS forms a stable complex with
Elongation Factor-1H (EF-1H), and together, they
catalyze consecutive steps in protein biosynthesis, tRNA
aminoacylation and its transfer to EF. The GST_C-like
domain of ValRS from higher eukaryotes is likely
involved in protein-protein interactions, to mediate the
formation of the multi-aaRS complex that acts as a
molecular hub to coordinate protein synthesis. ValRSs
from prokaryotes and lower eukaryotes, such as fungi and
plants, do not appear to contain this GST_C-like domain.

>gnl|CDD|198302 cd03193, GST_C_Metaxin, C-terminal, alpha helical domain of Metaxin
and related proteins. Glutathione S-transferase (GST)
C-terminal domain family, Metaxin subfamily; composed of
metaxins and related proteins. Metaxin 1 is a component
of a preprotein import complex of the mitochondrial
outer membrane. It extends to the cytosol and is
anchored to the mitochondrial membrane through its
C-terminal domain. In mice, metaxin is required for
embryonic development. In humans, alterations in the
metaxin gene may be associated with Gaucher disease.
Metaxin 2 binds to metaxin 1 and may also play a role in
protein translocation into the mitochondria. Genome
sequencing shows that a third metaxin gene also exists
in zebrafish, Xenopus, chicken, and mammals. Sequence
analysis suggests that all three metaxins share a common
ancestry and that they possess similarity to GSTs. Also
included in the subfamily are uncharacterized proteins
with similarity to metaxins, including a novel GST from
Rhodococcus with toluene o-monooxygenase and
glutamylcysteine synthetase activities. Other members
are the cadmium-inducible lysosomal protein CDR-1 and
its homologs from C. elegans, and the failed axon
connections (fax) protein from Drosophila. CDR-1 is an
integral membrane protein that functions to protect
against cadmium toxicity and may also have a role in
osmoregulation to maintain salt balance in C. elegans.
The fax gene of Drosophila was identified as a genetic
modifier of Abelson (Abl) tyrosine kinase. The fax
protein is localized in cellular membranes and is
expressed in embryonic mesoderm and axons of the central
nervous system.
