Elongation factor G (EF-G) catalyzes the translocation step of translation. It consists of five structural domains, this entry represents the second domain [1]. This domain adopts a beta barrel structure. This family also includes domains found in other translation factors such as translation initiation factor IF-2, peptide chain release factor, etc.	Domain

IF-2 is a translation initiator in each of the three main phylogenetic domains (Eukaryotes [1], Bacteria [2] and Archaea [3]). IF2 interacts with formylmethionine-tRNA, GTP, IF1, IF3 and both ribosomal subunits [2]. Through these interactions, IF2 promotes the binding of the initiator tRNA to the A site in the smaller ribosomal subunit and catalyses the hydrolysis of GTP following initiation-complex formation [2].
