Webb27 juni 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 … WebbRoles of mRNA, tRNA, rRNA. Translation requires the input of a messenger RNA (mRNA) template, ribosomes made up of ribosomal RNA (rRNA) and polypetide chains, and transfer RNAs (tRNAs) that carry amino acids to the growing polypeptide chain. Ribosomes are complex macromolecular factories, composed of four different structural rRNAs and …
