The addition of adenosine triphosphate (ATP) accelerates hydrazone-bond formation between an aldehyde and hydrazide and shifts the equilibrium reaction towards the product. Removal of the ATP using an enzyme largely reverses this beneficial effect and results in the formation of a kinetically stable state enriched in hydrazone. In this state, the reaction mixture has a higher catalytic activity compared
添加三磷酸腺苷 (ATP) 可加速醛和酰肼之间腙键的形成,并使平衡反应向产物方向移动。使用酶去除 ATP 在很大程度上逆转了这种有益效果,并导致形成富含腙的动力学稳定状态。在这种状态下,反应混合物与热力学平衡时的相同混合物相比具有更高的催化活性。
