 1-137 2.68e-99

P-loop containing Nucleoside Triphosphate Hydrolases; Members of the P-loop NTPase domain superfamily are characterized by a conserved nucleotide phosphate-binding motif, also referred to as the Walker A motif (GxxxxGK[S/T], where x is any residue), and the Walker B motif (hhhh[D/E], where h is a hydrophobic residue). The Walker A and B motifs bind the beta-gamma phosphate moiety of the bound nucleotide (typically ATP or GTP) and the Mg2+ cation, respectively. The P-loop NTPases are involved in diverse cellular functions, and they can be divided into two major structural classes: the KG (kinase-GTPase) class which includes Ras-like GTPases and its circularly permutated YlqF-like; and the ASCE (additional strand catalytic E) class which includes ATPase Binding Cassette (ABC), DExD/H-like helicases, 4Fe-4S iron sulfur cluster binding proteins of NifH family, RecA-like F1-ATPases, and ATPases Associated with a wide variety of Activities (AAA). Also included are a diverse set of nucleotide/nucleoside kinase families.

 1-137 2.68e-99

Elongation Factor 1-alpha (EF1-alpha) protein family; EF1 is responsible for the GTP-dependent binding of aminoacyl-tRNAs to the ribosomes. EF1 is composed of four subunits: the alpha chain which binds GTP and aminoacyl-tRNAs, the gamma chain that probably plays a role in anchoring the complex to other cellular components and the beta and delta (or beta') chains. This subfamily is the alpha subunit, and represents the counterpart of bacterial EF-Tu for the archaea (aEF1-alpha) and eukaryotes (eEF1-alpha). eEF1-alpha interacts with the actin of the eukaryotic cytoskeleton and may thereby play a role in cellular transformation and apoptosis. EF-Tu can have no such role in bacteria. In humans, the isoform eEF1A2 is overexpressed in 2/3 of breast cancers and has been identified as a putative oncogene. This subfamily also includes Hbs1, a G protein known to be important for efficient growth and protein synthesis under conditions of limiting translation initiation in yeast, and to associate with Dom34. It has been speculated that yeast Hbs1 and Dom34 proteins may function as part of a complex with a role in gene expression.

CysN, together with protein CysD, forms the ATP sulfurylase (ATPS) complex; CysN_ATPS subfamily. CysN, together with protein CysD, form the ATP sulfurylase (ATPS) complex in some bacteria and lower eukaryotes. ATPS catalyzes the production of ATP sulfurylase (APS) and pyrophosphate (PPi) from ATP and sulfate. CysD, which catalyzes ATP hydrolysis, is a member of the ATP pyrophosphatase (ATP PPase) family. CysN hydrolysis of GTP is required for CysD hydrolysis of ATP; however, CysN hydrolysis of GTP is not dependent on CysD hydrolysis of ATP. CysN is an example of lateral gene transfer followed by acquisition of new function. In many organisms, an ATPS exists which is not GTP-dependent and shares no sequence or structural similarity to CysN.

 2-137 8.71e-33

sulfate adenylyltransferase, large subunit; Metabolic assimilation of sulfur from inorganic sulfate, requires sulfate activation by coupling to a nucleoside, for the production of high-energy nucleoside phosphosulfates. This pathway appears to be similar in all prokaryotic organisms. Activation is first achieved through sulfation of sulfate with ATP by sulfate adenylyltransferase (ATP sulfurylase) to produce 5'-phosphosulfate (APS), coupled by GTP hydrolysis. Subsequently, APS is phosphorylated by an APS kinase to produce 3'-phosphoadenosine-5'-phosphosulfate (PAPS). In Escherichia coli, ATP sulfurylase is a heterodimer composed of two subunits encoded by cysD and cysN, with APS kinase encoded by cysC. These genes are located in a unidirectionally transcribed gene cluster, and have been shown to be required for the synthesis of sulfur-containing amino acids. Homologous to this E.coli activation pathway are nodPQH gene products found among members of the Rhizobiaceae family. These gene products have been shown to exhibit ATP sulfurase and APS kinase activity, yet are involved in Nod factor sulfation, and sulfation of other macromolecules. With members of the Rhizobiaceae family, nodQ often appears as a fusion of cysN (large subunit of ATP sulfurase) and cysC (APS kinase). [Central intermediary metabolism, Sulfur metabolism]

Elongation Factor Tu (EF-Tu) GTP-binding proteins; EF-Tu subfamily. This subfamily includes orthologs of translation elongation factor EF-Tu in bacteria, mitochondria, and chloroplasts. It is one of several GTP-binding translation factors found in the larger family of GTP-binding elongation factors. The eukaryotic counterpart, eukaryotic translation elongation factor 1 (eEF-1 alpha), is excluded from this family. EF-Tu is one of the most abundant proteins in bacteria, as well as, one of the most highly conserved, and in a number of species the gene is duplicated with identical function. When bound to GTP, EF-Tu can form a complex with any (correctly) aminoacylated tRNA except those for initiation and for selenocysteine, in which case EF-Tu is replaced by other factors. Transfer RNA is carried to the ribosome in these complexes for protein translation.

 4-120 1.38e-26

SelB, the dedicated elongation factor for delivery of selenocysteinyl-tRNA to the ribosome; SelB is an elongation factor needed for the co-translational incorporation of selenocysteine. Selenocysteine is coded by a UGA stop codon in combination with a specific downstream mRNA hairpin. In bacteria, the C-terminal part of SelB recognizes this hairpin, while the N-terminal part binds GTP and tRNA in analogy with elongation factor Tu (EF-Tu). It specifically recognizes the selenocysteine charged tRNAsec, which has a UCA anticodon, in an EF-Tu like manner. This allows insertion of selenocysteine at in-frame UGA stop codons. In E. coli SelB binds GTP, selenocysteyl-tRNAsec, and a stem-loop structure immediately downstream of the UGA codon (the SECIS sequence). The absence of active SelB prevents the participation of selenocysteyl-tRNAsec in translation. Archaeal and animal mechanisms of selenocysteine incorporation are more complex. Although the SECIS elements have different secondary structures and conserved elements between archaea and eukaryotes, they do share a common feature. Unlike in E. coli, these SECIS elements are located in the 3' UTRs. This group contains bacterial SelBs, as well as, one from archaea.

translation elongation factor TU; This model models orthologs of translation elongation factor EF-Tu in bacteria, mitochondria, and chloroplasts, one of several GTP-binding translation factors found by the more general pfam model GTP_EFTU. The eukaryotic conterpart, eukaryotic translation elongation factor 1 (eEF-1 alpha), is excluded from this model. EF-Tu is one of the most abundant proteins in bacteria, as well as one of the most highly conserved, and in a number of species the gene is duplicated with identical function. When bound to GTP, EF-Tu can form a complex with any (correctly) aminoacylated tRNA except those for initiation and for selenocysteine, in which case EF-Tu is replaced by other factors. Transfer RNA is carried to the ribosome in these complexes for protein translation. [Protein synthesis, Translation factors]

selenocysteine-specific elongation factor SelB; In prokaryotes, the incorporation of selenocysteine as the 21st amino acid, encoded by TGA, requires several elements: SelC is the tRNA itself, SelD acts as a donor of reduced selenium, SelA modifies a serine residue on SelC into selenocysteine, and SelB is a selenocysteine-specific translation elongation factor. 3-prime or 5-prime non-coding elements of mRNA have been found as probable structures for directing selenocysteine incorporation. This model describes the elongation factor SelB, a close homolog rf EF-Tu. It may function by replacing EF-Tu. A C-terminal domain not found in EF-Tu is in all SelB sequences in the seed alignment except that from Methanococcus jannaschii. This model does not find an equivalent protein for eukaryotes.

 3-137 2.89e-13

SelB, the dedicated elongation factor for delivery of selenocysteinyl-tRNA to the ribosome; SelB is an elongation factor needed for the co-translational incorporation of selenocysteine. Selenocysteine is coded by a UGA stop codon in combination with a specific downstream mRNA hairpin. In bacteria, the C-terminal part of SelB recognizes this hairpin, while the N-terminal part binds GTP and tRNA in analogy with elongation factor Tu (EF-Tu). It specifically recognizes the selenocysteine charged tRNAsec, which has a UCA anticodon, in an EF-Tu like manner. This allows insertion of selenocysteine at in-frame UGA stop codons. In E. coli SelB binds GTP, selenocysteyl-tRNAsec and a stem-loop structure immediately downstream of the UGA codon (the SECIS sequence). The absence of active SelB prevents the participation of selenocysteyl-tRNAsec in translation. Archaeal and animal mechanisms of selenocysteine incorporation are more complex. Although the SECIS elements have different secondary structures and conserved elements between archaea and eukaryotes, they do share a common feature. Unlike in E. coli, these SECIS elements are located in the 3' UTRs. This group contains eukaryotic SelBs and some from archaea.

 2-121 2.25e-11

LepA also known as Elongation Factor 4 (EF4); LepA (also known as elongation factor 4, EF4) belongs to the GTPase family and exhibits significant homology to the translation factors EF-G and EF-Tu, indicating its possible involvement in translation and association with the ribosome. LepA is ubiquitous in bacteria and eukaryota (e.g. yeast GUF1p), but is missing from archaea. This pattern of phyletic distribution suggests that LepA evolved through a duplication of the EF-G gene in bacteria, followed by early transfer into the eukaryotic lineage, most likely from the promitochondrial endosymbiont. Yeast GUF1p is not essential and mutant cells did not reveal any marked phenotype.

 3-99 2.69e-11

Tet(M)-like family includes Tet(M), Tet(O), Tet(W), and OtrA, containing tetracycline resistant proteins; Tet(M), Tet(O), Tet(W), and OtrA are tetracycline resistance genes found in Gram-positive and Gram-negative bacteria. Tetracyclines inhibit protein synthesis by preventing aminoacyl-tRNA from binding to the ribosomal acceptor site. This subfamily contains tetracycline resistance proteins that function through ribosomal protection and are typically found on mobile genetic elements, such as transposons or plasmids, and are often conjugative. Ribosomal protection proteins are homologous to the elongation factors EF-Tu and EF-G. EF-G and Tet(M) compete for binding on the ribosomes. Tet(M) has a higher affinity than EF-G, suggesting these two proteins may have overlapping binding sites and that Tet(M) must be released before EF-G can bind. Tet(M) and Tet(O) have been shown to have ribosome-dependent GTPase activity. These proteins are part of the GTP translation factor family, which includes EF-G, EF-Tu, EF2, LepA, and SelB.

Initiation Factor 2 (IF2)/ eukaryotic Initiation Factor 5B (eIF5B) family; IF2/eIF5B contribute to ribosomal subunit joining and function as GTPases that are maximally activated by the presence of both ribosomal subunits. As seen in other GTPases, IF2/IF5B undergoes conformational changes between its GTP- and GDP-bound states. Eukaryotic IF2/eIF5Bs possess three characteristic segments, including a divergent N-terminal region followed by conserved central and C-terminal segments.

 2-99 2.68e-08

Tyrosine phosphorylated protein A (TypA)/BipA family belongs to ribosome-binding GTPases; BipA is a protein belonging to the ribosome-binding family of GTPases and is widely distributed in bacteria and plants. BipA was originally described as a protein that is induced in Salmonella typhimurium after exposure to bactericidal/permeability-inducing protein (a cationic antimicrobial protein produced by neutrophils), and has since been identified in E. coli as well. The properties thus far described for BipA are related to its role in the process of pathogenesis by enteropathogenic E. coli. It appears to be involved in the regulation of several processes important for infection, including rearrangements of the cytoskeleton of the host, bacterial resistance to host defense peptides, flagellum-mediated cell motility, and expression of K5 capsular genes. It has been proposed that BipA may utilize a novel mechanism to regulate the expression of target genes. In addition, BipA from enteropathogenic E. coli has been shown to be phosphorylated on a tyrosine residue, while BipA from Salmonella and from E. coli K12 strains is not phosphorylated under the conditions assayed. The phosphorylation apparently modifies the rate of nucleotide hydrolysis, with the phosphorylated form showing greatly increased GTPase activity.

 30-125 2.76e-07

GTP binding protein 1 (GTPBP1)-like family includes GTPBP2; Mammalian GTP binding protein 1 (GTPBP1), GTPBP2, and nematode homologs AGP-1 and CGP-1 are GTPases whose specific functions remain unknown. In mouse, GTPBP1 is expressed in macrophages, in smooth muscle cells of various tissues and in some neurons of the cerebral cortex; GTPBP2 tissue distribution appears to overlap that of GTPBP1. In human leukemia and macrophage cell lines, expression of both GTPBP1 and GTPBP2 is enhanced by interferon-gamma (IFN-gamma). The chromosomal location of both genes has been identified in humans, with GTPBP1 located in chromosome 22q12-13.1 and GTPBP2 located in chromosome 6p21-12. Human glioblastoma multiforme (GBM), a highly-malignant astrocytic glioma and the most common cancer in the central nervous system, has been linked to chromosomal deletions and a translocation on chromosome 6. The GBM translocation results in a fusion of GTPBP2 and PTPRZ1, a protein involved in oligodendrocyte differentiation, recovery, and survival. This fusion product may contribute to the onset of GBM.

Snu114p, a spliceosome protein, is a GTPase; Snu114p subfamily. Snu114p is one of several proteins that make up the U5 small nuclear ribonucleoprotein (snRNP) particle. U5 is a component of the spliceosome, which catalyzes the splicing of pre-mRNA to remove introns. Snu114p is homologous to EF-2, but typically contains an additional N-terminal domain not found in Ef-2. This protein is part of the GTP translation factor family and the Ras superfamily, characterized by five G-box motifs.

 4-64 8.00e-07

Release Factor 3 (RF3) protein involved in the terminal step of translocation in bacteria; Peptide chain release factor 3 (RF3) is a protein involved in the termination step of translation in bacteria. Termination occurs when class I release factors (RF1 or RF2) recognize the stop codon at the A-site of the ribosome and activate the release of the nascent polypeptide. The class II release factor RF3 then initiates the release of the class I RF from the ribosome. RF3 binds to the RF/ribosome complex in the inactive (GDP-bound) state. GDP/GTP exchange occurs, followed by the release of the class I RF. Subsequent hydrolysis of GTP to GDP triggers the release of RF3 from the ribosome. RF3 also enhances the efficiency of class I RFs at less preferred stop codons and at stop codons in weak contexts.

 2-41 1.74e-06

Elongation factor G (EF-G) family involved in both the elongation and ribosome recycling phases of protein synthesis; Translocation is mediated by EF-G (also called translocase). The structure of EF-G closely resembles that of the complex between EF-Tu and tRNA. This is an example of molecular mimicry; a protein domain evolved so that it mimics the shape of a tRNA molecule. EF-G in the GTP form binds to the ribosome, primarily through the interaction of its EF-Tu-like domain with the 50S subunit. The binding of EF-G to the ribosome in this manner stimulates the GTPase activity of EF-G. On GTP hydrolysis, EF-G undergoes a conformational change that forces its arm deeper into the A site on the 30S subunit. To accommodate this domain, the peptidyl-tRNA in the A site moves to the P site, carrying the mRNA and the deacylated tRNA with it. The ribosome may be prepared for these rearrangements by the initial binding of EF-G as well. The dissociation of EF-G leaves the ribosome ready to accept the next aminoacyl-tRNA into the A site. This group contains both eukaryotic and bacterial members.

The eukaryotic elongation factor eEF2 is a GTPase involved in the translocation of the peptidyl-tRNA from the A site to the P site on the ribosome. The 95-kDa protein is highly conserved, with 60% amino acid sequence identity between the human and yeast proteins. Two major mechanisms are known to regulate protein elongation and both involve eEF2. First, eEF2 can be modulated by reversible phosphorylation. Increased levels of phosphorylated eEF2 reduce elongation rates presumably because phosphorylated eEF2 fails to bind the ribosomes. Treatment of mammalian cells with agents that raise the cytoplasmic Ca2+ and cAMP levels reduce elongation rates by activating the kinase responsible for phosphorylating eEF2. In contrast, treatment of cells with insulin increases elongation rates by promoting eEF2 dephosphorylation. Second, the protein can be post-translationally modified by ADP-ribosylation. Various bacterial toxins perform this reaction after modification of a specific histidine residue to diphthamide, but there is evidence for endogenous ADP ribosylase activity. Similar to the bacterial toxins, it is presumed that modification by the endogenous enzyme also inhibits eEF2 activity.
