>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|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.

>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.

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.

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

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.

class Sigma and similar proteins, including GSTs from
class Mu, Pi, and Alpha. 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,

GSH binds to the N-terminal domain while the hydrophobic
substrate occupies a pocket in the C-terminal domain.
Vertebrate class Sigma GSTs are 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.

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

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

only distantly related to the mitochondrial GSTs (GSTK).
Soluble GSTs bear no structural similarity to microsomal

polymorphisms which may influence individual
susceptibility to diseases such as cancer, arthritis,
allergy and sclerosis. Some GST family members with

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|239353 cd03055, GST_N_Omega, GST_N family, Class Omega 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
TRX-fold domain and a C-terminal alpha helical domain,
with an active site located in a cleft between the two
domains. Class Omega GSTs show little or no
GSH-conjugating activity towards standard GST
substrates. Instead, they catalyze the GSH dependent
reduction of protein disulfides, dehydroascorbate and
monomethylarsonate, activities which are more
characteristic of glutaredoxins. They contain a
conserved cysteine equivalent to the first cysteine in
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.

family has been characterized as a regulator of RNase E
and its crystal structure has been analyzed. This model
was initially classified as a "hypothetical equivalog"
expressing the tentative hypothesis that all members
might have the same function as the E. coli enzyme.
Considering the second clade of enterobacterial
sequences within this family, that appears to be less
tenable. The function of these sequences outside of the
narrow RraA equivalog model (TIGR02998) remains obscure.
All of these were initially annotated as MenG, AKA
S-adenosylmethionine: 2-demethylmenaquinone
methyltransferase (EC 2.1.-.-). See the references
characterizing this as a case of transitive annotation
error in the case of the E. coli protein [Unknown

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|239274 cd02976, NrdH, NrdH-redoxin (NrdH) family; NrdH is a small
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.
