應用

磷酸(烯醇)丙酮酸三钠盐水合物用于:
  • 一些酶活性测定,例如 PRPP合成酶(PRPPS)测定、核糖激酶(RK)测定,腺嘌呤磷酸核糖基转移酶(APRT)测定
  • 反应混合物,进行酶动力学测定,确定血小板衍生生长因子受体 α (PDGFRA)的动力学参数
  • 作为缓冲液B成分,与二磷酸腺苷(ADP)反应,形成三磷酸腺苷(ATP),进行能荷测量

生化/生理作用

磷酸烯醇丙酮酸作为抑制剂,通过抑制己糖激酶、磷酸葡萄糖异构酶、磷酸果糖激酶和醛缩酶,在糖酵解的初始步骤中起主要作用。
磷酸(烯醇)丙酮酸 (PEP) 参与糖酵解和糖异生。在糖酵解中,PEP 被丙酮酸激酶代谢生成丙酮酸。在植物中,PEP 参与芳香族氨基酸的形成以及碳固定途径。
