- initiation factors
The set of catalytic proteins required, in addition to mRNA and ribosomes, for protein synthesis to begin. In bacteria three distinct proteins have been identified: IF-1 (8 kD),IF-2 (75 kD) and IF-3 (30 kD). At least 6-8 proteins have been identified in eukaryotes. IFs 1 and 2 enhance the binding of initiator tRNA to the initiation complex.

Prokaryotic initiation factors — Prokaryotes require the use of three initiation factors: IF1, IF2, and IF3, for translation. IF1 IF1 associates with the 30S ribosomal subunit in the A site and prevents an aminoacyl tRNA from entering. It modulates IF2 binding to the ribosome by … Wikipedia
