PROTEIN SYNTHESIS INHIBITORS

PROTEIN SYNTHESIS INHIBITORS. INTRODUCTION. These antibiotics exert their actions by targeting the bacterial ribosomal subunit at various steps in the synthesis of bacterial protein. Bacterial ribosome is smaller 70 s as compared to the mammalian cytoplasmic ribosome - 80 s.

The tRNA i Met is needed to start synthesis of a polypeptide chain

7. two types of tRNAs exist for the methionine codon. tRNA i Met is exclusively used for initiation of a polypeptide chain. tRNA Met is exclusively used for elongation of a polypeptide chain. The tRNA i Met is needed to start synthesis of a polypeptide chain.

eukaryotic translation initiation factor 5

Eukaryotic translation initiation factor-5 (EIF5) interacts with the 40S initiation complex to promote hydrolysis of;bound GTP with concomitant joining of the 60S ribosomal subunit to the 40S initiation complex. The resulting;functional 80S ribosomal initiation complex is then active in peptidyl transfer and chain elongations (summary by Si;et al., 1996 (PubMed 8663286)).
