Certain bacterial mutant lacks the kinase catalyzing the reaction ATP + GDP ADP + GTP but otherwise possesses enzymes similar to those in mammals. This mutant could still produce GTP from GDP by utilizing the enzyme

Question

Certain bacterial mutant lacks the kinase catalyzing the reaction ATP + GDP <==> ADP + GTP but otherwise possesses enzymes similar to those in mammals. This mutant could still produce GTP from GDP by utilizing the enzyme

Quizplus · Accepted Answer

Succinate thiokinase, also known as succinyl-CoA synthetase, catalyzes the reaction succinyl-CoA + GDP <==> succinate + GTP. Therefore, the bacterial mutant lacking the kinase for ATP + GDP <==> ADP + GTP could still produce GTP from GDP by utilizing succinate thiokinase.
