WebKinetic data have shown that the hydrolysis of GTP is very rapid and precedes translocation [31,180,181,182,183]. On the other hand, it has been demonstrated that EF-G can bind to the ribosome in either the classical or hybrid state to promote translocation [ 42 , 44 , 184 ], but favors the hybrid configuration [ 30 , 185 , 186 ].

The new aminoacyl tRNA now comes and connects itself to the aminoacyl or A site of the ribosome. The tRNAs on the A site and P sites of the ribosomes are connected using peptide bonds. We consider this as the initiation of the second step of elongation.

Web7 okt. 2024 · With time, intrinsic guanosine triphosphatase (GTPase) activity of the Gα subunits leads to GTP hydrolysis; the activity further sped up by the dedicated RGS (regulator of G protein signaling) proteins ( 3 ). The resultant Gα-GDP can reload with GTP ( 4) or complex back with Gβγ, thus closing the G protein activation-deactivation loop ( 2 ).
