Question

Quizplus · Accepted Answer

EF-Ts (Elongation Factor-Thermus aquaticus) is responsible for exchanging GTP (Guanosine Triphosphate) for GDP (Guanosine Diphosphate) in the elongation factor EF-Tu (Elongation Factor-Thermus aquaticus), enabling it to bind another aminoacyl-tRNA and elongate the polypeptide. Therefore, it does not hydrolyze GTP, hydrolyze GDP or deliver the aminoacyl-tRNA to the ribosome.
