prokaryotic initiation factor 1 《英文msh词典》Prokaryotic Initiation Factor 1 ; [入口词] Prokaryotic Initiation Factor 1 ; [主题词] Prokaryotic Initiation Factor-1 ; [英文释义] The smallest of the three prokaryotic initiation factors with a molecular size of approximately 8 kD. It binds near the A-site of the 30S subunit of RIBOSOMES and may play a role in preventing premature addition of aminoacyl-tRNA-linked PEPTIDE ELONGATION FACTOR TU to the ribosome during PEPTIDE CHAIN INITIATION.
prokaryotic initiation factor 2 《英文msh词典》Prokaryotic Initiation Factor 2 ; [入口词] Prokaryotic Initiation Factor 2 ; [主题词] Prokaryotic Initiation Factor-2 ; [英文释义] 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.
