GST_N family, Class Zeta 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 Zeta GSTs, also known as maleylacetoacetate (MAA) isomerases, catalyze the isomerization of MAA to fumarylacetoacetate, the penultimate step in tyrosine/phenylalanine catabolism, using GSH as a cofactor. They show little GSH-conjugating activity towards traditional GST substrates but display modest GSH peroxidase activity. They are also implicated in the detoxification of the carcinogen dichloroacetic acid by catalyzing its dechlorination to glyoxylic acid.

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.

7-83 | 1.17e-10 | ||||
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.

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.

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.

GST_N family, Gamma subunit of Elongation 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.

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.

GST_N family, Class Alpha 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. The class Alpha subfamily is composed of eukaryotic GSTs which can form homodimer and heterodimers. There are at least six types of class Alpha GST subunits in rats, four of which have human counterparts, resulting in many possible isoenzymes with different activities, tissue distribution and substrate specificities. Human GSTA1-1 and GSTA2-2 show high GSH peroxidase activity. GSTA3-3 catalyzes the isomerization of intermediates in steroid hormone biosynthesis. GSTA4-4 preferentially catalyzes the GSH conjugation of alkenals. Pssm-ID: 239375 Cd Length: 79 Bit Score: 35.20 E-value: 2.26e-03

GST_N family, unknown subfamily 2; composed of uncharacterized bacterial proteins with similarity to GSTs. 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 sequence from Burkholderia cepacia was identified as part of a gene cluster involved in the degradation of 2,4,5-trichlorophenoxyacetic acid. Some GSTs (e.g. Class Zeta and Delta) are known to catalyze dechlorination reactions. Pssm-ID: 239345 [Multi-domain] Cd Length: 73 Bit Score: 34.60 E-value: 3.55e-03
