[https://www.uniprot.org/uniprot/IF2_GEOSE IF2_GEOSE] One of the essential components for the initiation of protein synthesis. Protects formylmethionyl-tRNA from spontaneous hydrolysis and promotes its binding to the 30S ribosomal subunits. Also involved in the hydrolysis of GTP during the formation of the 70S ribosomal complex.

== Publication Abstract from PubMed ==

IF2 is one of three bacterial translation initiation factors that are conserved through all kingdoms of life. It binds the 30S and 50S ribosomal subunits, as well as fMet-tRNAf(Met). After these interactions, fMet-tRNAf(Met) is oriented to the ribosomal P-site where the first amino acid of the nascent polypeptide, formylmethionine, is presented. The C-terminal domain of Bacillus stearothermophilus IF2, which is responsible for recognition and binding of fMet-tRNAf(Met), contains two structured modules. Previously, the solution structure of the most C-terminal module, IF2-C2, has been elucidated by NMR spectroscopy and direct interactions between this subdomain and fMet-tRNAf(Met) were reported. In the present NMR study we have obtained the spectral assignment of the other module of the C-terminal domain (IF2-C1) and determined its solution structure and backbone dynamics. The IF2-C1 core forms a flattened fold consisting of a central four-stranded parallel beta-sheet flanked by three alpha-helices. Although its overall organization resembles that of subdomain III of the archaeal IF2-homolog eIF5B whose crystal structure had previously been reported, some differences of potential functional significance are evident.
