Peptide Chain Elongation: Discrimination against the Initiator Transfer RNA by Microbial Amino-acid Polymerization Factors

Abstract

The amino-acid polymerization factors S1 and S3 form complexes with most aminoacyl-tRNA species, including met-tRNAM, but not F-met-tRNAF and not met-tRNAF. This discrimination may be a basis for avoiding one kind of ambiguity in translation.
