>gnl|CDD|239343 cd03045, GST_N_Delta_Epsilon, GST_N 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
TRX-fold domain and a C-terminal alpha helical domain,
with an active site located in a cleft between the two
domains. 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|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|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.

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|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 peroxidase activity and are
involved in the synthesis of prostaglandins and
leukotrienes.

Factor 1B (EFB1gamma) 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 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 (methionine sulfoxide reductase) promoter
suggesting a function in the regulation of its gene
expression.

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.

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

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

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

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

vertebrates), p64, parchorin, and similar proteins.
They are auto-inserting, self-assembling intracellular
anion channels involved 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, and they may play roles in the
maintenance of these intracellular membranes.
Biochemical studies of the Caenorhabditis elegans
homolog, EXC-4, show that the membrane localization
domain is present in the N-terminal part of the
protein. CLICs display structural plasticity, with
CLIC1 adopting two soluble conformations. The structure
of soluble human CLIC1 reveals that it is monomeric and
adopts a fold similar to GSTs, containing an N-terminal
domain with a thioredoxin 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.

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

Beta 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. Unlike
mammalian GSTs which detoxify a broad range of
compounds, the bacterial class Beta GSTs exhibit GSH
conjugating activity with a narrow range of substrates.
In addition to GSH conjugation, they are involved in
the protection against oxidative stress and are able to
bind antibiotics and reduce the antimicrobial activity
of beta-lactam drugs, contributing to antibiotic
resistance. The structure of the Proteus mirabilis
enzyme reveals that the cysteine in the active site
forms a covalent bond with GSH. One member of this
subfamily is a GST from Burkholderia xenovorans LB400
that is encoded by the bphK gene and is part of the
biphenyl catabolic pathway.

Mu subfamily is composed of eukaryotic GSTs. In rats,
at least six distinct class Mu subunits have been
identified, with homologous genes in humans for five of
these subunits. Class Mu GSTs can form homodimers and
heterodimers, giving a large number of possible
isoenzymes that can be formed, all with overlapping
activities but different substrate 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.

characterized as GSH-dependent hematopoietic
prostaglandin (PG) D synthases and are responsible for
the production of PGD2 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-like members include the class II insect GSTs,
S-crystallins from cephalopods, nematode-specific GSTs,
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. Members also include novel
GSTs from the fungus Cunninghamella elegans, designated
as class Gamma, and from the protozoan Blepharisma
japonicum, described as a light-inducible GST.

involved in the ubiquitylation and proteasomal
degradation of its substrates. Mutations in the Parkin
gene is found in 50% of patients with
autosomal-recessive early-onset parkinsonism. The

Escherichia coli Yghu Glutathione S-transferases and
related uncharacterized proteins. Glutathione
S-transferase (GST) C-terminal domain family, YghU-like
subfamily; composed of the Escherichia coli YghU and
related proteins. 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 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.

(SspA) subfamily; SspA is a RNA polymerase
(RNAP)-associated protein required for the lytic
development of phage P1 and for stationary phase-induced
acid tolerance of E. coli. It is implicated in survival
during nutrient starvation. SspA adopts the GST fold
with an N-terminal TRX-fold domain and a C-terminal
alpha helical domain, but it does not bind glutathione
(GSH) and lacks GST activity. SspA is highly conserved
among gram-negative bacteria. Related proteins found in
Neisseria (called RegF), Francisella and Vibrio regulate
the expression of virulence factors necessary for
pathogenesis.

Ure2p Glutathione S-transferases. Glutathione
S-transferase (GST) C-terminal domain family, Ure2p
subfamily; composed of the Saccharomyces cerevisiae
Ure2p and related fungal 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. 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

Glutathione S-transferase (GST) C-terminal domain
family, Saccharomyces cerevisiae Omega-like subfamily;
composed of three Saccharomyces cerevisiae GST
omega-like (Gto) proteins, Gto1p, Gto2p (also known as
Extracellular mutant protein 4 or ECM4p), and Gto3p, as
well as similar uncharacterized proteins from fungi and
bacteria. The three Saccharomyces cerevisiae Gto
proteins are omega-class GSTs with low or no GST
activity against standard substrates, but have
glutaredoxin/thiol oxidoreductase and dehydroascorbate
reductase activity through a single cysteine residue in
the active site. Gto1p is located in the peroxisomes
while Gto2p and Gto3p are cytosolic. The gene encoding
Gto2p, called ECM4, is involved in cell surface
biosynthesis and architecture. S. cerevisiae ECM4
mutants show increased amounts of the cell wall hexose,
N-acetylglucosamine. More recently, global gene
expression analysis shows that ECM4 is upregulated
during genotoxic conditions and together with the
expression profiles of 18 other genes could potentially
differentiate between genotoxic and cytotoxic insults
in yeast.

>gnl|CDD|187693 cd07180, RNase_HII_Archaea_like, Archaeal ribonuclease HII.
Ribonuclease (RNase) H is classified into two families,
type I (prokaryotic RNase HI, eukaryotic RNase H1 and
viral RNase H) and type II (prokaryotic RNase HII and
HIII, archaeal RNase HII and eukaryotic RNase H2/HII).
RNase H endonucleolytically hydrolyzes an RNA strand
when it is annealed to a complementary DNA strand in the
presence of divalent cations, in DNA replication or
repair. Some archaeal RNase HII show broad divalent
cation specificity. It is proposed that three of the
four acidic residues at the active site are involved in
metal binding and the fourth one involved in the
catalytic process in archaea. Most archaeal genomes
contain multiple RNase H genes. Despite a lack of
evidence for homology from sequence comparisons, type I
and type II RNase H share a common fold and similar
steric configurations of the four acidic active-site
residues, suggesting identical or very similar catalytic
mechanisms. It appears that type I and type II RNases H
also have overlapping functions in cells, as
over-expression of Escherichia coli RNase HII can
complement an RNase HI deletion phenotype in E. coli.

Dehydroascorbate Reductase. Glutathione S-transferase
(GST) C-terminal domain family, Dehydroascorbate
Reductase (DHAR) subfamily; composed of plant-specific
DHARs, which are monomeric enzymes catalyzing the
reduction of DHA into ascorbic acid (AsA) using
glutathione as the reductant. DHAR allows plants to
recycle oxidized AsA before it is lost. AsA serves as a
cofactor of violaxanthin de-epoxidase in the
xanthophyll cycle and as an antioxidant in the
detoxification of reactive oxygen species. Because AsA
is the major reductant in plants, DHAR serves to
regulate their redox state. It has been suggested that
a significant portion of DHAR activity is plastidic,
acting to reduce the large amounts of ascorbate
oxidized during hydrogen peroxide scavenging by
ascorbate peroxidase. DHAR contains a conserved
cysteine in its active site and in addition to its
reductase activity, shows thiol transferase activity
similar to glutaredoxins.
