GST_N family, Class Beta 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. Unlike mammalian GSTs which detoxify a broad range of compounds, the bacterial class Beta GSTs exhibit limited GSH conjugating activity with a narrow range of substrates. In addition to GSH conjugation, they also bind antibiotics and reduce the antimicrobial activity of beta-lactam drugs. The structure of the Proteus mirabilis enzyme reveals that the cysteine in the active site forms a covalent bond with GSH.

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.

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.

C-terminal, alpha helical domain of Ure2p and related Glutathione S-transferase-like proteins; Glutathione S-transferase (GST) C-terminal 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 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.

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 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.

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.

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.

Glutathione S-transferase, N-terminal domain; Function: conjugation of reduced glutathione to a variety of targets. Also included in the alignment, but not GSTs: S-crystallins from squid (similarity to GST previously noted); eukaryotic elongation factors 1-gamma (not known to have GST activity and similarity not previously recognized); HSP26 family of stress-related proteins including auxin-regulated proteins in plants and stringent starvation proteins in E. coli (not known to have GST activity and similarity not previously recognized). The glutathione molecule binds in a cleft between the N- and C-terminal domains - the catalytically important residues are proposed to reside in the N-terminal domain.
