Peptide Initiation Factor IF-2 .
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. .

Peptide Initiation Factor IF-3 .
A prokaryotic initiation factor that plays a role in recycling of ribosomal subunits for a new round of translational initiation. It binds to 16S RIBOSOMAL RNA and stimulates the dissociation of vacant 70S ribosomes. It may also be involved in the preferential binding of initiator tRNA to the 30S initiation complex. .

Translation Initiation Factors, Prokaryotic .
Peptide initiation factors from prokaryotic organisms. Only three factors are needed for translation initiation in prokaryotic organisms, which occurs by a far simpler process than in PEPTIDE CHAIN INITIATION, TRANSLATIONAL of eukaryotic organisms. .

Peptide Chain Initiation .
A process of GENETIC TRANSLATION whereby the formation of a peptide chain is started. It includes assembly of the RIBOSOME components, the MESSENGER RNA coding for the polypeptide to be made, INITIATOR TRNA, and PEPTIDE INITIATION FACTORS; and placement of the first amino acid in the peptide chain. The details and components of this process are unique for prokaryotic protein biosynthesis and eukaryotic protein biosynthesis. .
