In initiation First the 70s ribosome must separate into 50s and 30s subunits. The 3 initiation factors IF-1, IF-2, and IF-3 then bind to the 30S ribosomal subunit. Then the specific initiator tRNA carrying the N-formylmethionine and the mRNA join the complex (remember base pairing via Shine-Dalgarno sequence). The initiator tRNA is specifically recognized by IF-2.

Unformatted text preview: • At this point in the process we have what is termed a 30s preinitiation complex . • The 50S subunit binds, triggering the release of the IFs. Thus, formation of the 70S initiation complex is completed and it is ready for the next phase, elongation....
