Scope note

  • The largest of the three prokaryotic initiation factors with a molecular size of approximately 80 kD. It functions in the transcription initiation process by promoting the binding of formylmethionine-tRNA to the P-site of the 30S ribosome and by preventing the incorrect binding of elongator tRNA to the translation initiation site.

History note

  • 2003; use PROKARYOTIC INITIATION FACTOR-2 (NM) 1990-2002
