DE RecName: Full=Translation initiation factor IF-2; GN Name=infB; OrderedLocusNames=FTW_0126; OS Francisella tularensis subsp. tularensis (strain WY96-3418). OC Bacteria; Proteobacteria; Gammaproteobacteria; Thiotrichales; OC Francisellaceae; Francisella. OX NCBI_TaxID=418136; RN [1] RP NUCLEOTIDE SEQUENCE [LARGE SCALE GENOMIC DNA]. RC STRAIN=WY96-3418; RX PubMed=17895988; DOI=10.1371/journal.pone.0000947; RA Beckstrom-Sternberg S.M., Auerbach R.K., Godbole S., Pearson J.V., RA Beckstrom-Sternberg J.S., Deng Z., Munk C., Kubota K., Zhou Y., RA Bruce D., Noronha J., Scheuermann R.H., Wang A., Wei X., Wang J., RA Hao J., Wagner D.M., Brettin T.S., Brown N., Gilna P., Keim P.S.; RT "Complete genomic characterization of a pathogenic A.II strain of RT Francisella tularensis subspecies tularensis."; RL PLoS ONE 2:E947-E947(2007). CC -!- FUNCTION: One of the essential components for the initiation of CC protein synthesis. Protects formylmethionyl-tRNA from spontaneous CC hydrolysis and promotes its binding to the 30S ribosomal subunits. CC Also involved in the hydrolysis of GTP during the formation of the CC 70S ribosomal complex (By similarity). CC -!- SUBCELLULAR LOCATION: Cytoplasm (By similarity). CC -!- SIMILARITY: Belongs to the IF-2 family.
