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.

1-76 | 3.68e-07 | ||||
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. Pssm-ID: 239346 [Multi-domain] Cd Length: 81 Bit Score: 46.38 E-value: 3.68e-07

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. 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 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. The GST active site is located in a cleft between the N- and C-terminal domains.

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, Ganglioside-induced differentiation-associated protein 1 (GDAP1) subfamily; GDAP1 was originally identified as a highly expressed gene at the differentiated stage of GD3 synthase-transfected cells. More recently, mutations in GDAP1 have been reported to cause both axonal and demyelinating autosomal-recessive Charcot-Marie-Tooth (CMT) type 4A neuropathy. CMT is characterized by slow and progressive weakness and atrophy of muscles. Sequence analysis of GDAP1 shows similarities and differences with GSTs; it appears to contain both N-terminal TRX-fold and C-terminal alpha helical domains of GSTs, however, it also contains additional C-terminal transmembrane domains unlike GSTs. GDAP1 is mainly expressed in neuronal cells and is localized in the mitochondria through its transmembrane domains. It does not exhibit GST activity using standard substrates.

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. 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 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.

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.

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.
