translation initiation factor IF-3 [Nocardioidaceae bacterium]

Protein Classification

translation initiation factor IF-3( domain architecture ID 11416658)

translation initiation factor IF-3 (InfC) is one of the essential components for the initiation of protein synthesis which binds to the 30S ribosomal subunit and shifts the equilibrum between 70S ribosomes and their 50S and 30S subunits in favor of the free subunits, thus enhancing the availability of 30S subunits on which protein synthesis initiation begins
