Prokaryotic Initiation Factor-1
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 the initiation of a peptide chain (PEPTIDE CHAIN INITIATION, TRANSLATIONAL).
