WebApr 27, 2016 · Abstract. During protein synthesis, tRNA and mRNA are translocated from the A to P to E sites of the ribosome thus enabling the ribosome to translate one codon of mRNA after the other. Ribosome translocation along mRNA is induced by the universally conserved ribosome GTPase, elongation factor G (EF-G) in bacteria and elongation factor … WebDuring protein synthesis, the mRNA and tRNAs must be moved synchronously through the ribosome, to vacate the A site for the next incoming aminoacyl-tRNA while preserving the translational reading frame. This process, called translocation, is catalyzed by the GTPase elongation factor G (EF-G) (1, 2).
