丙酮酸羧化酶：（Pyruvate Carboxylase）催化丙酮酸羧化生成草酰乙酸的酶，其辅酶为生物素。
催化丙酮酸羧化生成草酰乙酸的酶，其辅酶为生物素。反应分两步：第一步，CO2与生物素结合；第二步，活化的CO2再转移给丙酮酸生成草酰乙酸。在糖异生途径中其逆过程由2个反应组成，催化第一个反应的酶是丙酮酸羧化酶，催化第二个反应的酶是磷酸烯醇式丙酮酸激酶，催化草酰乙酸转变成烯醇式丙酮酸。
Date: EC 6.4.1.1. Catalytic acetone acerbity carboxyl is changed those who make acid of careless acyl second is enzymatic, its complementary enzymatic for biology element. Reaction divides a pace: The first pace, CO2Be united in wedlock with biology element; The 2nd pace, the CO of activation2Transfer acetone acid to make acid of careless acyl second again. In candy different strange way its go against a process to be comprised by 2 reaction, what catalysis reacts the first times is enzymatic it is acetone acerbity carboxyl is changed enzymatic, what catalysis reacts the 2nd times is enzymatic it is acerbity kinase of acetone of pure form of phosphoric acid Xi, change of acid of second of catalytic careless acyl becomes sick at heart of acetone of Xi pure form.
