Are transferases involved in pyruvate conversion?

Yes, transferases are involved in pyruvate conversion. Pyruvate conversion is catalyzed by the pyruvate dehydrogenase enzyme, which is part of the multienzyme Pyruvate dehydrogenase complex (PDC). This is a complex composed of three enzymes that catalyze the irreversible decarboxylation of pyruvate into acetyl-CoA.
