  • Peptide Initiation Factor IF-1
  • Prokaryotic Peptide Initiation Factor 1

Scope note

  • 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).

History note

  • 2003; for IF-1 use EUKARYOTIC INITIATION FACTOR-1 1990-2002
