>gnl|CDD|239337 cd03039, GST_N_Sigma_like, GST_N family, Class Sigma_like;
composed of GSTs belonging to 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, 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. 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 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
elegans, designated as class Gamma, and from the
protozoan Blepharisma japonicum, described as a
light-inducible GST.

Class Sigma-like Glutathione S-transferases.
Glutathione S-transferase (GST) C-terminal domain
family, Class Sigma_like; composed of GSTs belonging to
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,
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.
Vertebrate class Sigma GSTs are characterized as

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 Pi GST is a homodimeric eukaryotic
protein. The human GSTP1 is mainly found in
erythrocytes, kidney, placenta and fetal liver. It is
involved in stress responses and in cellular
proliferation pathways as an inhibitor of JNK (c-Jun
N-terminal kinase). Following oxidative stress,
monomeric GSTP1 dissociates from JNK and dimerizes,
losing its ability to bind JNK and causing an increase
in JNK activity, thereby promoting apoptosis. GSTP1 is
expressed in various tumors and is the predominant GST
in a wide range of cancer cells. It has been implicated
in the development of multidrug-resistant tumours.

>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.

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

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.

believed to mediate the dimerization of the EF1
complex, which in yeast is a dimer of the heterotrimer

>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.

Glutathione S-transferases. Glutathione S-transferase
(GST) C-terminal domain family, Class Mu 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. The class 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.

Metaxin-like proteins; a heterogenous group of
proteins, predominantly uncharacterized, with
similarity to metaxins and GSTs. 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.
One characterized member of this subgroup is a novel
GST from Rhodococcus with toluene o-monooxygenase and
gamma-glutamylcysteine synthetase activities. Also
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.

subgroup, a delta-12 acyl-lipid desaturase-like,
DesA-like, yet uncharacterized subgroup of membrane
fatty acid desaturase proteins found in alpha-, beta-,
and gamma-proteobacteria. Sequences of this domain
family appear to be structurally related to membrane
fatty acid desaturases and alkane hydroxylases. They all
share in common extensive hydrophobic regions that would
be capable of spanning the membrane bilayer at least
twice. Comparison of these sequences also reveals three
regions of conserved histidine cluster motifs that
contain eight histidine residues: HXXXH, HXXHH, and
HXXHH. These histidine residues are reported to be
catalytically essential and proposed to be the ligands
for the iron atoms contained within homologs, stearoyl
CoA desaturase and alkane hydroxylase.

RhoA-binding protein Rhophilin-1. This subfamily
contains the Bro1-like domain of the RhoA-binding
protein, Rhophilin-1. It belongs to the BRO1_Alix_like
superfamily which also includes the Bro1-like domains of
mammalian Alix (apoptosis-linked gene-2 interacting
protein X), His-Domain type N23 protein tyrosine
phosphatase (HD-PTP, also known as PTPN23), RhoA-binding
protein Rhophilin-2, Brox, Bro1 and Rim20 (also known as
PalA) from Saccharomyces cerevisiae, Ustilago maydis
Rim23 (also known as PalC), and related domains.
Rhophilin-1 binds both GDP- and GTP-bound RhoA.
Bro1-like domains are boomerang-shaped, and part of the
domain is a tetratricopeptide repeat (TPR)-like
structure. In addition to this Bro1-like domain,
Rhophilin-1 contains an N-terminal Rho-binding domain
and a C-terminal PDZ (PS.D.-95, Disc-large, ZO-1)
domain. The Drosophila knockout of the Rhophilin-1 is
embryonic lethal, suggesting an essential role in
embryonic development. The isolated Bro1-like domain of
Rhophilin-1 binds human immunodeficiency virus type 1
(HIV-1) nucleocapsid. Rhophilin-1 lacks the V-shaped (V)
domain found in many members of the BRO1_Alix_ like
superfamily.

topoisomerase-primase (TORPIM) domain found in members
of the type IA family of DNA topoisomerases (Topo IA)
similar to topoisomerase III. Type IA DNA
topoisomerases remove (relax) negative supercoils in
the DNA by: cleaving one strand of the DNA duplex,
covalently linking to the 5' phosphoryl end of the DNA
break and, allowing the other strand of the duplex to
pass through the gap. The TOPRIM domain has two
conserved motifs, one of which centers at a conserved
glutamate and the other one at two conserved aspartates
(DxD). For topoisomerases the conserved glutamate is
believed to act as a general base in strand joining
and, as a general acid in strand cleavage. The DXD
motif may co-ordinate Mg2+, a cofactor required for
full catalytic function.
