lepA_C: This family represents the C-terminal region of LepA, a GTP-binding protein localized in the cytoplasmic membrane. LepA is ubiquitous in Bacteria and Eukaryota (e.g. Saccharomyces cerevisiae GUF1p), but is missing from Archaea. LepA exhibits significant homology to elongation factors (EFs) Tu and G. The function(s) of the proteins in this family are unknown. The N-terminal domain of LepA is homologous to a domain of similar size found in initiation factor 2 (IF2), and in EF-Tu and EF-G (factors required for translation in Escherichia coli). Two types of phylogenetic tree, rooted by other GTP-binding proteins, suggest that eukaryotic homologs (including S. cerevisiae GUF1) originated within the bacterial LepA family. LepA has never been observed in archaea, and eukaryl LepA is organellar. LepA is therefore a true bacterial GTPase, found only in the bacterial lineage.

Elongation factor G C-terminus. This domain includes the carboxyl terminal regions of elongation factors (EFs) bacterial EF-G, eukaryotic and archeal EF-2 and eukaryotic mitochondrial mtEFG1s and mtEFG2s. This group also includes proteins similar to the ribosomal protection proteins Tet(M) and Tet(O), BipA, LepA and, spliceosomal proteins: human 116kD U5 small nuclear ribonucleoprotein (snRNP) protein (U5-116 kD) and yeast counterpart Snu114p. This domain adopts a ferredoxin-like fold consisting of an alpha-beta sandwich with anti-parallel beta-sheets, resembling the topology of domain III found in the elongation factors EF-G and eukaryotic EF-2, with which it forms the C-terminal block. The two domains however are not superimposable and domain III lacks some of the characteristics of this domain. EF-2/EF-G in complex with GTP, promotes the translocation step of translation. During translocation the peptidyl-tRNA is moved from the A site to the P site, the uncharged tRNA from the P site to the E-site and, the mRNA is shifted one codon relative to the ribosome. Tet(M) and Tet(O) mediate Tc resistance. Typical Tcs bind to the ribosome and inhibit the elongation phase of protein synthesis, by inhibiting the occupation of site A by aminoacyl-tRNA. Tet(M) and Tet(O) catalyze the release of tetracycline (Tc) from the ribosome in a GTP-dependent manner. BipA is a highly conserved protein with global regulatory properties in Escherichia coli. Yeast Snu114p is essential for cell viability and for splicing in vivo. Experiments suggest that GTP binding and probably GTP hydrolysis is important for the function of the U5-116 kD/Snu114p. The function of LepA proteins is unknown. Pssm-ID: 238772 [Multi-domain] Cd Length: 79 Bit Score: 99.48 E-value: 2.79e-26

Domain III of Elongation factor G (EF-G) and related proteins; Bacterial Elongation factor G (EF-G) and related proteins play a role in translation and share a similar domain architecture. Elongation factor EFG participates in the elongation phase during protein biosynthesis on the ribosome by stimulating translocation. Its functional cycles depend on GTP binding and its hydrolysis. Domain III is involved in the activation of GTP hydrolysis. This domain III, which is different from domain III in EF-TU and related elongation factors, is found in several translation factors, like bacterial release factors RF3, elongation factor 4, elongation factor 2, GTP-binding protein BipA and tetracycline resistance protein Tet.

EFG_mtEFG_C: domains similar to the C-terminal domain of the bacterial translational elongation factor (EF) EF-G. Included in this group is the C-terminus of mitochondrial Elongation factor G1 (mtEFG1) and G2 (mtEFG2) proteins. Eukaryotic cells harbor 2 protein synthesis systems: one localized in the cytoplasm, the other in the mitochondria. Most factors regulating mitochondrial protein synthesis are encoded by nuclear genes, translated in the cytoplasm, and then transported to the mitochondria. The eukaryotic system of elongation factor (EF) components is more complex than that in prokaryotes, with both cytoplasmic and mitochondrial elongation factors and multiple isoforms being expressed in certain species. During the process of peptide synthesis and tRNA site changes, the ribosome is moved along the mRNA a distance equal to one codon with the addition of each amino acid. In bacteria this translocation step is catalyzed by EF-G_GTP, which is hydrolyzed to provide the required energy. Thus, this action releases the uncharged tRNA from the P site and transfers the newly formed peptidyl-tRNA from the A site to the P site. Eukaryotic mtEFG1 proteins show significant homology to bacterial EF-Gs. Mutants in yeast mtEFG1 have impaired mitochondrial protein synthesis, respiratory defects and a tendency to lose mitochondrial DNA. No clear phenotype has been found for mutants in the yeast homologue of mtEFG2, MEF2. Pssm-ID: 239683 [Multi-domain] Cd Length: 78 Bit Score: 53.69 E-value: 1.57e-09

BipA_TypA_C: a C-terminal portion of BipA or TypA having homology to the C terminal domains of the elongation factors EF-G and EF-2. A member of the ribosome binding GTPase superfamily, BipA is widely distributed in bacteria and plants. BipA is a highly conserved protein with global regulatory properties in Escherichia coli. BipA is phosphorylated on a tyrosine residue under some cellular conditions. Mutants show altered regulation of some pathways. BipA functions as a translation factor that is required specifically for the expression of the transcriptional modulator Fis. BipA binds to ribosomes at a site that coincides with that of EF-G and has a GTPase activity that is sensitive to high GDP:GTP ratios and, is stimulated by 70S ribosomes programmed with mRNA and aminoacylated tRNAs. The growth rate-dependent induction of BipA allows the efficient expression of Fis, thereby modulating a range of downstream processes, including DNA metabolism and type III secretion.

Domain III of bacterial Release Factor 3 (RF3); The class II RF3 is a member of one of two release factor (RF) classes required for the termination of protein synthesis by the ribosome. RF3 is a GTPase that removes class I RFs (RF1 or RF2) from the ribosome after release of the nascent polypeptide. RF3 in the GDP state binds to the ribosomal class I RF complex, followed by an exchange of GDP for GTP and release of the class I RF. Sequence comparison of class II release factors with elongation factors shows that prokaryotic RF3 is more similar to EF-G whereas eukaryotic eRF3 is more similar to eEF1A, implying that their precise function may differ.
