Phospholipid depletion substantially inhibited the maximum demonstrable activities of the forward (glucuronidation) and reverse reactions of UDP-glucuronyltransferase towards p-nitrophenol in guinea-pig liver microsomal preparations. Dispersions of liver phospholipids restored activity, whereas non-phospholipid amphipaths failed to do so effectively. These results suggest that the system is probably phospholipid-dependent rather than conformationally constrained by phospholipids.
磷脂耗竭在很大程度上抑制了豚鼠肝微粒体制剂中UDP-葡糖醛酸基转移酶对对硝基苯酚的正向(葡糖醛酸化)和逆向反应的最大可显示活性。肝磷脂分散体可恢复活性,而非磷脂两性离子则不能有效恢复活性。这些结果表明,该系统可能依赖于磷脂,而非受磷脂的构象限制。
