>TIGR00487 IF-2 translation initiation factor IF-2; InterPro: IPR000178 Initiation factor 2 (IF-2) (gene infB) is one of the three factors required for the initiation of protein biosynthesis in bacteria. IF-2 promotes the GTP-dependent binding of the initiator tRNA to the small subunit of the ribosome. IF-2 is a protein of about 70 to 95 Kd which contains a central GTP-binding domain flanked by a highly variable N-terminal domain and a more conserved C-terminal domain. Bacterial IF-2 is structurally and functionally related to eukaryotic mitochondrial IF-2 (IF-2(mt)) as well as to algal and plants chloroplast IF-2 (IF-2(chl)). Both IF-2(mt) and IF-2(chl) are encoded by nuclear genes and are produced as precursor proteins with a transit peptide. An exception are red algae where IF-2(chl) is encoded by the plastid genome .; GO: 0003743 translation initiation factor activity, 0005525 GTP binding, 0006413 translational initiation, 0005622 intracellular.
