WebJun 27, 2005 · Small GTPases play central roles in catalyzing each stage of protein synthesis on the ribosome. In prokaryotes, the relevant GTPases are: initiation factor IF2, which delivers the initiator tRNA to the P (peptide) site of the 30S ribosomal subunit; elongation factor EF-Tu, which delivers the aminoacyl-tRNA to the 70S ribosome … WebThe protein translation by a ribosome consists of three stages: (1) Initiation, (2) Elongation, and (3) Termination. Initiation – the ribosome assembles around the target mRNA. A small ribosome subunit links onto the “start-end” of an mRNA strand. “Initiator tRNA” also enters the small subunit and binds to the start codon (most commonly, AUG).
