#Unit 3. Fundamental Processes

The initiation of prokaryotic translation commences with the small subunit and is catalyzed by three translation initiation factors called IF1, IF2, and IF3.

IF1 prevents tRNAs from binding to the portion of the small subunit that will become part of the A-site.

#Unit 3. Fundamental Processes

IF2 is a GTPase (a protein that binds and hydrolyzes GTP) that interacts with three key components of the initiation machinery: the small subunit, IF1, and the charged initiator tRNA (fMet-tRNAi fMet).

IF3 binds to the small subunit and blocks it from reassociating with a large subunit.
