Glutathione S-transferase C-terminal-like, alpha helical domain of the Gamma subunit of Elongation Factor 1B and similar proteins; Glutathione S-transferase (GST) C-terminal domain family, Gamma subunit of Elongation Factor 1B (EF1Bgamma) 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 thioredoxin-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 to 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. Also included in this subfamily is the GST_C-like domain at the N-terminus of human valyl-tRNA synthetase (ValRS) and its homologs. Metazoan ValRS forms a stable complex with Elongation Factor-1H (EF-1H), and together, they catalyze consecutive steps in protein biosynthesis, tRNA aminoacylation and its transfer to EF. : Pssm-ID: 198290 [Multi-domain] Cd Length: 123 Bit Score: 230.53 E-value: 1.01e-69

Aminoacyl-tRNA synthetases (aaRSs) comprise a family of enzymes that catalyze the coupling of amino acids with their matching tRNAs. This involves the formation of an aminoacyl adenylate using ATP, followed by the transfer of the activated amino acid to the 3'-adenosine moiety of the tRNA. AaRSs may also be involved in translational and transcriptional regulation, as well as in tRNA processing. They typically form large stable complexes with other proteins. ValRS forms a stable complex with Elongation Factor-1H (EF-1H), and together, they catalyze consecutive steps in protein biosynthesis, tRNA aminoacylation and its transfer to EF. The GST_C-like domain of ValRS from higher eukaryotes is likely involved in protein-protein interactions, to mediate the formation of the multi-aaRS complex that acts as a molecular hub to coordinate protein synthesis. ValRSs from prokaryotes and lower eukaryotes, such as fungi and plants, do not appear to contain this GST_C-like domain.

AaRSs may also be involved in translational and transcriptional regulation, as well as in tRNA processing. AaRSs in this subfamily include GluRS from lower eukaryotes, as well as GluProRS, MetRS, and CysRS from higher eukaryotes. AIMPs are non-enzymatic cofactors that play critical roles in the assembly and formation of a macromolecular multi-tRNA synthetase protein complex found in higher eukaryotes. The GST_C-like domain is involved in protein-protein interactions, mediating the formation of aaRS complexes such as the MetRS-Arc1p-GluRS ternary complex in lower eukaryotes and the multi-aaRS complex in higher eukaryotes, that act as molecular hubs for protein synthesis. AaRSs from prokaryotes, which are active as dimers, do not contain this GST_C-like domain. Pssm-ID: 198322 [Multi-domain] Cd Length: 82 Bit Score: 71.19 E-value: 1.46e-14

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). 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, and aminoacyl-tRNA synthetases.

There are three AIMPs, named AIMP1-3, which play diverse regulatory roles. AIMP3, also called p18 or eukaryotic translation elongation factor 1 epsilon-1 (EEF1E1), contains a C-terminal domain with similarity to the C-terminal alpha helical domain of GSTs. It specifically interacts with methionyl-tRNA synthetase (MetRS) and is translocated to the nucleus during DNA synthesis or in response to DNA damage and oncogenic stress. In the nucleus, it interacts with ATM and ATR, which are upstream kinase regulators of p53. It appears to work against DNA damage in cooperation with AIMP2, and similar to AIMP2, AIMP3 is also a haploinsufficient tumor suppressor. AIMP3 transgenic mice have shorter lifespans than wild-type mice and they show characteristics of progeria, suggesting that AIMP3 may also be involved in cellular and organismal aging.

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.

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.

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.

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.

This SYNJ2BP-like family domain is a canonical PDZ domain containing six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2), arranged in the order: beta-strands A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F.

126-169 | 5.11e-03 | |||||||||||
C-terminal, alpha helical domain of 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.

permuted PDZ domain of Deg/high-temperature requirement factor A (HtrA) family of housekeeping serine proteases and related domains; PDZ (PSD-95 (Postsynaptic density protein 95), Dlg (Discs large protein), and ZO-1 (Zonula occludens-1)) domain of Deg/HtrA-type serine proteases that participate in folding and degradation of aberrant proteins, and in processing and maturation of native proteins. Typically, these proteases have an N-terminal serine protease domain and at least one C-terminal PDZ domain that recognizes substrates, and in some cases activates the protease function. An exception is yeast Nma11p which has two protease domains and four PDZ domains; its N-terminal half is comprised of a protease domain, followed by two PDZ domains, and its C-terminal half has a similar domain arrangement. HtrA-type proteases include the human HtrA1-4 and MBTPS2, tricorn protease, DegS, DegP and C-terminal processing peptidase, cyanobacterial serine proteases Hhoa, HhoB, and HtrA, and yeast Nma11p. PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-termini of their partner proteins (known as PDZ binding motifs). The PDZ superfamily includes canonical PDZ domains and as well as those with circular permutations and domain swapping of beta-strands. The canonical PDZ domain contains six beta-strands A-F and two alpha-helices (alpha-helix 1 and 2); arranged as A, B, C, alpha-helix 1, beta-strands D, E, alpha-helix 2 and beta-strand F. This Deg/HtrA family PDZ domain is a circularly permuted PDZ domain which places beta-strand A at the C-terminus. Another permutation exists in the PDZ superfamily which places both beta-strands A and B on the C-terminus. Pssm-ID: 467621 [Multi-domain] Cd Length: 91 Bit Score: 38.81 E-value: 5.37e-03

C-terminal, alpha helical domain of Escherichia coli Yghu Glutathione S-transferases and related uncharacterized proteins; Glutathione S-transferase (GST) C-terminal domain family, YghU-like subfamily; composed of the Escherichia coli YghU and related proteins. 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. YghU is one of nine GST homologs in the genome of Escherichia coli. It is similar to Escherichia coli YfcG in that it has poor GSH transferase activity towards typical substrates. It shows modest reductase activity towards some organic hydroperoxides. Like YfcG, YghU also shows good disulfide bond oxidoreductase activity comparable to the activities of glutaredoxins and thioredoxins. YghU 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 YghU reveals two GSH molecules bound in its active site. Pssm-ID: 198325 [Multi-domain] Cd Length: 118 Bit Score: 39.37 E-value: 6.19e-03

C-terminal, alpha helical domain of fungal Ure2p Glutathione S-transferases; Glutathione S-transferase (GST) C-terminal domain family, Ure2p subfamily; composed of the Saccharomyces cerevisiae Ure2p and related fungal 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. 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.

RapGEF2 and RapGEF6 constitute a subfamily of guanine nucleotide exchange factors (GEFs) for RAP small GTPases that is characterized by the possession of the PDZ and Ras/Rap-associating domains. They activate Rap small GTPases, by catalyzing the release of GDP from the inactive GDP-bound forms, thereby accelerating GTP loading to yield the active GTP-bound forms. The PDZ domain of RapGEF6 (also known as PDZ-GEF2) binds junctional adhesion molecule A (JAM-A). PDZ domains usually bind in a sequence-specific manner to short peptide sequences located at the C-terminal end of their partner proteins (known as PDZ binding motifs).
