Protein Domain : IPR000795

Type:  Domain Name:  Transcription factor, GTP-binding domain
Description:  The translational GTPases are the Bacteria elongation factors, EFTu, EFG, and the initiation factor, IF2, and their archaeal homologues, the EF1, EF2, aeIF5b and aeIF2. They all contain two homologous N-terminal domains: a GTPase or G-domain, followed by an OB-domain. These translational proteins' G-domains are both structurally and functionally related to a larger family of GTPase G proteins [].In both prokaryotes and eukaryotes, there are three distinct types of elongation factors, EF-1alpha (EF-Tu), which binds GTP and an aminoacyl-tRNAand delivers the latter to the A site of ribosomes; EF-1beta (EF-Ts), which interacts with EF-1a/EF-Tu to displace GDP and thus allows the regeneration of GTP-EF-1a; and EF-2 (EF-G), which binds GTP and peptidyl-tRNA and translocates the latter from the A site to the P site. In EF-1-alpha, a specific region has been shown [] to be involved in a conformational change mediated by the hydrolysis of GTP to GDP. This region is conserved in both EF-1alpha/EF-Tu as well as EF-2/EF-G and thus seems typical for GTP-dependent proteins which bind non-initiator tRNAs to the ribosome. The GTP-binding protein synthesis factor family also includes the eukaryotic peptide chain release factor GTP-binding subunits [] and prokaryotic peptide chain release factor 3 (RF-3) []; the prokaryotic GTP-binding protein lepA and its homologue in yeast(GUF1) and Caenorhabditis elegans(ZK1236.1); yeast HBS1 []; rat statin S1 []; and the prokaryotic selenocysteine-specific elongation factor selB [].
