During the elongation cycle of protein biosynthesis on the ribosome, elongation factor G (EF-G), a GTPase, facilitates the translocation of the A- and P-site tRNAs to the P and E sites, respectively, ...
Several of the steps in protein synthesis on the ribosome utilize hydrolysis of guanosine triphosphate (GTP) as the driving force. This reaction is catalyzed by translation factors that become ...
Dynamin assembles into a ring around the neck of a forming vesicle and utilizes GTP hydrolysis energy to constrict and sever the membrane. The simulation reveals that the dynamin ring expands (loosens ...
