pyruvate kinase : ウィキペディア英語版 | pyruvate kinase
Pyruvate kinase is an enzyme involved in glycolysis. It catalyzes the transfer of a phosphate group from phosphoenolpyruvate (PEP) to ADP, yielding one molecule of pyruvate and one molecule of ATP. ==Reaction== The pyruvate kinase reaction: This process also requires a magnesium ion. The enzyme is a 'transferase' under the international classification of enzymes. This step is the final one in the glycolytic pathway, which produces pyruvate molecules, the final product of aerobic glycolysis. However, in anaerobic glycolysis, lactate dehydrogenase will utilize the NADH produced by glyceraldehyde phosphate dehydrogenase to reduce pyruvate to lactate. In humans, there are two pyruvate kinase isozymes: type M (muscle, SwissProt P14618) and type L,R (liver and erythrocyte, SwissProt P30613). The isozymes differ in primary structure and regulation.
