Which of the following is NOT a part of the transketolase-catalyzed reaction?

Question

Quizplus · Accepted Answer

The transketolase-catalyzed reaction involves the formation of a Schiff base intermediate between the enzyme's active-site lysine and a keto-carbonyl group on a substrate molecule, followed by transfer of a two-carbon unit from the ketose substrate to a different aldose substrate, resulting in the formation of a new ketose and a new aldose. The Schiff base intermediate is then hydrolyzed, releasing the newly formed ketose product and regenerating the active enzyme. However, there is no b-cleavage of the Schiff base intermediate in this reaction.
