What is probably responsible for driving the conformational shift that is required for the release of the IF2-GDP initiation factor from the initiation complex?
A)hydrolysis of ATP bound to IF2
B)hydrolysis of the GTP bound to IF2
C)binding of IF1
D)degradation of IF3
E)GDP condensation

Question

Quizplus · Accepted Answer

Hydrolysis of the GTP bound to IF2 is likely responsible for driving the conformational shift that allows for the release of the IF2-GDP initiation factor from the initiation complex. This hydrolysis releases phosphate and causes a conformational change in IF2 that allows it to dissociate from the complex.
