| Abstract | Initiation factor 3 (IF-3) (gene infC) is one of the three factors required for the
initiation of protein biosynthesis in bacteria. IF-3 is thought to function as a
fidelity factor during the assembly of the ternary initiation complex which consist of
the 30S ribosomal subunit, the initiator tRNA and the messenger RNA. IF-3 is a basic
protein that binds to the 30S ribosomal subunit [ 8405963]. The chloroplast initiation factor IF-3(chl) is a protein that
enhances the poly(A,U,G)-dependent binding of the initiator tRNA to chloroplast ribosomal
30s subunits in which the central section is evolutionary related to the sequence of
bacterial IF-3 [8144528]. |
