Abstract
Protein biosynthesis is a complex biochemical process involving a number of stages at which different translation factors specifically interact with ribosome. Some of these factors belong to GTP-binding proteins, or G-proteins. Due to their functioning, GTP is hydrolyzed to yield GDP and the inorganic phosphate ion Pi. Interaction with ribosome enhances GTPase activity of translation factors; i.e., ribosome plays a role of GTPase-activating protein (GAP). GTPases involved in translation interact with ribosome at every stage of protein biosynthesis. Initiation factor 2 (IF2) catalyzes initiator tRNA binding to the ribosome P site and subsequent binding of the 50S subunit to the initiation complex of the 30S subunit. Elongation factor Tu (EF-Tu) controls aminoacyl-tRNA delivery to the ribosome A site, while elongation factor G (EF-G) catalyzes translocation of the mRNA-tRNA complex by one codon on the ribosome. Release factor 3 (RF3) catalyzes the release of termination factors 1 or 2 (RF1 or RF2) from the ribosomal complex after completion of protein synthesis and peptidyl-tRNA hydrolysis. The functional properties of translational GTPases as related to other G-proteins, the putative mechanism of GTP hydrolysis, structural features, and the functional cycles of translational GTPases are considered.
