>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|215674 pfam00043, GST_C, Glutathione S-transferase, C-terminal domain.
GST conjugates reduced glutathione to a variety of
targets including S-crystallin from squid, the
eukaryotic elongation factor 1-gamma, the HSP26 family
of stress-related proteins and auxin-regulated proteins
in plants. Stringent starvation proteins in E. coli are
also included in the alignment but are not known to have
GST activity. The glutathione molecule binds in a cleft
between N and C-terminal domains. The catalytically
important residues are proposed to reside in the
N-terminal domain. In plants, GSTs are encoded by a
large gene family (48 GST genes in Arabidopsis) and can
be divided into the phi, tau, theta, zeta, and lambda
classes.

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

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,

The GST fold contains an N-terminal TRX-fold domain and

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.

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
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.

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

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

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 the 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 the aryl or alkyl sulfate esters.

Hck is a member of the Src subfamily of proteins, which
are cytoplasmic (or non-receptor) tyr kinases. Src
kinases contain an N-terminal SH4 domain with a
myristoylation site, followed by SH3 and SH2 domains, a
tyr kinase domain, and a regulatory C-terminal region
containing a conserved tyr. They are activated by
autophosphorylation at the tyr kinase domain, but are
negatively regulated by phosphorylation at the
C-terminal tyr by Csk (C-terminal Src Kinase). Src
proteins are involved in signaling pathways that
regulate cytokine and growth factor responses,
cytoskeleton dynamics, cell proliferation, survival, and
differentiation. Hck is present in myeloid and lymphoid
cells that play a role in the development of cancer. It
may be important in the oncogenic signaling of the
protein Tel-Abl, which induces a chronic myelogenous
leukemia (CML)-like disease. Hck also acts as a negative
regulator of granulocyte colony-stimulating factor
(G-CSF)-induced proliferation of granulocytic
precursors, suggesting a possible role in the
development of acute myeloid leukemia (AML). In
addition, Hck is essential in regulating the
degranulation of polymorphonuclear leukocytes (PMNs).
Genetic polymorphisms affect the expression level of
Hck, which affects PMN mediator release and influences
the development of chronic obstructive pulmonary disease
(COPD).

Sigma Glutathione S-transferases. Glutathione

Sigma; 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 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.

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.

>gnl|CDD|173641 cd05072, PTKc_Lyn, Catalytic domain of the Protein Tyrosine Kinase,
Lyn. Protein Tyrosine Kinase (PTK) family; Lyn kinase;
catalytic (c) domain. The PTKc family is part of a
larger superfamily that includes the catalytic domains
of other kinases such as protein serine/threonine
kinases, RIO kinases, and phosphoinositide 3-kinase
(PI3K). PTKs catalyze the transfer of the
gamma-phosphoryl group from ATP to tyrosine (tyr)
residues in protein substrates. Lyn is a member of the
Src subfamily of proteins, which are cytoplasmic (or
non-receptor) tyr kinases. Src kinases contain an
N-terminal SH4 domain with a myristoylation site,
followed by SH3 and SH2 domains, a tyr kinase domain,
and a regulatory C-terminal region containing a
conserved tyr. They are activated by autophosphorylation
at the tyr kinase domain, but are negatively regulated
by phosphorylation at the C-terminal tyr by Csk
(C-terminal Src Kinase). Src proteins are involved in
signaling pathways that regulate cytokine and growth
factor responses, cytoskeleton dynamics, cell
proliferation, survival, and differentiation. Lyn is
expressed in B lymphocytes and myeloid cells. It
exhibits both positive and negative regulatory roles in
B cell receptor (BCR) signaling. Lyn, as well as Fyn and
Blk, promotes B cell activation by phosphorylating ITAMs
(immunoreceptor tyr activation motifs) in CD19 and in Ig
components of BCR. It negatively regulates signaling by
its unique ability to phosphorylate ITIMs
(immunoreceptor tyr inhibition motifs) in cell surface
receptors like CD22 and CD5. Lyn also plays an important
role in G-CSF receptor signaling by phosphorylating a
variety of adaptor molecules.

Metaxin 1-like proteins; composed of metaxins 1 and 3,
and similar proteins including Tom37 from fungi.
Mammalian metaxin (or metaxin 1) and the fungal protein
Tom37 are components of preprotein import complexes of
the mitochondrial outer membrane. Metaxin extends to
the cytosol and is anchored to the mitochondrial
membrane through its C-terminal domain. In mice,
metaxin is required for embryonic development. Like the
murine gene, the human metaxin gene is located
downstream to the glucocerebrosidase (GBA) pseudogene
and is convergently transcribed. Inherited deficiency
of GBA results in Gaucher disease, which presents many
diverse clinical phenotypes. Alterations in the metaxin
gene, in addition to GBA mutations, may be associated
with Gaucher disease. Genome sequencing shows that a
third metaxin gene also exists in zebrafish, Xenopus,
chicken and mammals.

Members of this family belong to the iron-dependent
alcohol dehydrogenase family (see pfam00465). The
NADP(H) cofactor is bound too tightly for exchange
(although non-convalently), so enzymatic activity
depends on a second substrate or electron carrier. The
radical SAM-modified natural product mycofactocin is
proposed to fill this role.
