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.

Domain III of Elongation Factor (EF) Tu; EF-Tu consists of three structural domains, designated I, II, and III. Domain III adopts a beta barrel structure. Domain III is involved in binding to both charged tRNA and to elongation factor Ts (EF-Ts). EF-Ts is the guanine-nucleotide-exchange factor for EF-Tu. EF-Tu and EF-G participate in the elongation phase during protein biosynthesis on the ribosome. Their functional cycles depend on GTP binding and its hydrolysis. The EF-Tu complexed with GTP and aminoacyl-tRNA delivers tRNA to the ribosome, whereas EF-G stimulates translocation, a process in which tRNA and mRNA movements occur in the ribosome. Crystallographic studies revealed structural similarities ("molecular mimicry") between tertiary structures of EF-G and the EF-Tu-aminoacyl-tRNA ternary complex. Domains III, IV, and V of EF-G mimic the tRNA structure in the EF-Tu ternary complex; domains III, IV and V can be related to the acceptor stem, anticodon helix and T stem of tRNA respectively.

1-86 | 2.57e-50 | ||||
Domain II of elongation factor Tu; Elongation factors Tu (EF-Tu) are three-domain GTPases with an essential function in the elongation phase of mRNA translation. The GTPase center of EF-Tu is in the N-terminal domain (domain I), also known as the catalytic or G-domain. The G-domain is composed of about 200 amino acid residues, arranged into a predominantly parallel six-stranded beta-sheet core surrounded by seven alpha helices. Non-catalytic domains II and III are beta-barrels of seven and six, respectively, antiparallel beta-strands that share an extended interface. Both non-catalytic domains are composed of about 100 amino acid residues. EF-Tu proteins exist in two principal conformations: a compact one, EF-Tu*GTP, with tight interfaces between all three domains and a high affinity for aminoacyl-tRNA; and an open one, EF-Tu*GDP, with essentially no G-domain-domain II interactions and a low affinity for aminoacyl-tRNA. EF-Tu has approximately a 100-fold higher affinity for GDP than for GTP. Pssm-ID: 293898 [Multi-domain] Cd Length: 87 Bit Score: 156.91 E-value: 2.57e-50

Domain III of mitochondrial EF-TU (mtEF-TU); mtEF-TU is highly conserved and is 55-60% identical to bacterial EF-TU. The overall structure is similar to that observed in the Escherichia coli and Thermus aquaticus EF-TU. However, compared with that observed in prokaryotic EF-TU, the nucleotide-binding domain (domain I) of mtEF-TU is in a different orientation relative to the rest of the structure. Furthermore, domain III is followed by a short 11-amino acid extension that forms one helical turn. This extension seems to be specific to the mitochondrial factors and has not been observed in any of the prokaryotic factors.

Domain II of elongation factor 1-alpha; This family represents domain II of elongation factor 1-alpha (EF-1A) that is found in archaea and all eukaryotic lineages. EF-1A is very abundant in the cytosol, where it is involved in the GTP-dependent binding of aminoacyl-tRNAs to the A site of the ribosomes in the second step of translation from mRNAs to proteins. Both domain II of EF-1A and domain IV of IF2/eIF5B have been implicated in recognition of the 3'-ends of tRNA. More than 61% of eukaryotic elongation factor 1A (eEF-1A) in cells is estimated to be associated with actin cytoskeleton. The binding of eEF-1A to actin is a noncanonical function that may link two distinct cellular processes, cytoskeleton organization and gene expression.

Experimental findings indicate an essential contribution of domain III to activation of GTP hydrolysis. This domain III, which is distinct from the domain III in EFG and related elongation factors, is found in several eukaryotic translation factors, like peptide chain release factors RF3, elongation factor 1, selenocysteine (Sec)-specific elongation factor, and in GT-1 family of GTPase (GTPBP1).

Domain II of the GTPBP family of GTP binding proteins; This group includes proteins similar to GTPBP1 and GTPBP2. GTPBP1 is structurally related to elongation factor 1 alpha, a key component of the protein biosynthesis machinery. Immunohistochemical analyses on mouse tissues revealed that GTPBP1 is expressed in some neurons and smooth muscle cells of various organs as well as macrophages. Immunofluorescence analyses revealed that GTPBP1 is localized exclusively in cytoplasm and shows a diffuse granular network forming a gradient from the nucleus to the periphery of the cells in smooth muscle cell lines and macrophages. No significant difference was observed in the immune response to protein antigen between mutant mice and wild-type mice, suggesting normal function of antigen-presenting cells of the mutant mice. The absence of an eminent phenotype in GTPBP1-deficient mice may be due to functional compensation by GTPBP2, which is similar to GTPBP1 in structure and tissue distribution.

Domain II of the large subunit of ATP sulfurylase; This subfamily represents domain II of the large subunit of ATP sulfurylase (ATPS): CysN or the N-terminal portion of NodQ, found mainly in proteobacteria and homologous to the domain II of EF-Tu. Escherichia coli ATPS consists of CysN and a smaller subunit CysD. ATPS produces adenosine-5'-phosphosulfate (APS) from ATP and sulfate, coupled with GTP hydrolysis. In the subsequent reaction, APS is phosphorylated by an APS kinase (CysC), to produce 3'-phosphoadenosine-5'-phosphosulfate (PAPS) for use in amino acid (aa) biosynthesis. The Rhizobiaceae group (alpha-proteobacteria) appears to carry out the same chemistry for the sulfation of a nodulation factor. In Rhizobium meliloti, the heterodimeric complex comprised of NodP and NodQ appears to possess both ATPS and APS kinase activities. The N and C termini of NodQ correspond to CysN and CysC, respectively. Other eubacteria, archaea, and eukaryotes use a different ATP sulfurylase, which shows no amino acid sequence similarity to CysN or NodQ. CysN and the N-terminal portion of NodQ show similarity to GTPases involved in translation, in particular, EF-Tu and EF-1alpha.

2-82 | 9.68e-05 | ||||
Domain II of the eukaryotic class II release factor; In eukaryotes, translation termination is mediated by two interacting release factors, eRF1 and eRF3, which act as class I and II factors, respectively. eRF1 functions as an omnipotent release factor, decoding all three stop codons and triggering the release of the nascent peptide catalyzed by the ribosome. eRF3 is a GTPase, which enhances termination efficiency by stimulating eRF1 activity in a GTP-dependent manner. Sequence comparison of class II release factors with elongation factors shows that eRF3 is more similar to eEF-1alpha whereas prokaryote RF3 is more similar to EF-G, implying that their precise function may differ. Only eukaryote RF3s are found in this group. Saccharomyces cerevisiae eRF3 (Sup35p) is a translation termination factor which is divided into three regions N, M and a C-terminal eEF1a-like region essential for translation termination. Sup35NM is a non-pathogenic prion-like protein with the property of aggregating into polymer-like fibrils. Pssm-ID: 293906 [Multi-domain] Cd Length: 82 Bit Score: 39.39 E-value: 9.68e-05

Domain II of BipA; BipA (also called TypA) 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. The domain II of BipA shows similarity to the domain II of the elongation factors (EFs) EF-G and EF-Tu. Pssm-ID: 293892 [Multi-domain] Cd Length: 94 Bit Score: 36.01 E-value: 1.97e-03
