摘　　要：质膜Ｈ＋┐ＡＴＰａｓｅ磷酸化对其活性的调节＊凌启阆向左云刘华尚克进（南开大学生物化学及分子生物学系，天津３０００７１）ＲｅｇｕｌａｔｉｏｎｏｆＰＭＨ＋┐ＡＴＰａｓｅＡｃｔｉｖｉｔｙｂｙＩｔｓＰｈｏｓｐｈｏｒｙｌａｔｉｏｎＬｉｎｇＱｉ－ＬａｎｇＸｉａｎ...The relationship between phosphorylation and activity of plasma membrane H+ATPase(PM H+ATPase)in the invivo treatments of auxin (IAA) and chlorpromazine(CPZ)has been investigated.The study shows that IAA not only improves the level of PM H+ATPase phosphorylation but also induces its activity.On the other hand,CPZ inhibits the activity of PM H+ATPase and its phosphorylation level at the same time.Statistical analysis demonstrates that an extremely positive correlation exists between the level of phosphorylation and the activity of PM H+ATPase.These results suggest that the activity of PM H+ATPase is regulated by its phosphorylation.
