摘要
Protein synthesis involves initiation,elongation,and termination.A number of studies show that translation elongation is highly regulated and is the most energy-intensive process,which controls the efficiency and accuracy of protein synthesis.In the elongation process,eukaryotic elongation factor 2(eEF2)binds to the ribosome to induce its conformation change and promotes the translocation of the tRNAs by hydrolyzing guanosine triphosphate,which then allows the next AA-tRNA to enter the A site for translation elongation.The activity of eEF2 is negatively regulated by its kinase eEF2K that phosphorylates eEF2 at threonine-56(Thr56).
