摘要：

Phosphorylation/dephosphorylation of plasma membrane H+-ATPase acts as a regulator to control the H+-ATPase activity. In this work a plasmalemma-enriched fraction from wheat root and a partially purified H+-ATPase were used to investigate the effects of Ca2+ and calmodulin on the H+-ATPase activity and its phosphorylation status, The hydrolytic activities increased approximately 40% by mumol l(-1) Ca2+, while calmodulin did not have any effect neither alone nor in the presence of Ca2+, indicating that calmodulin is not involved in the process. However, when adding stauosporine, a kinase inhibitor. the stimulating effect of Ca2+ was eliminated. Moreover. partially purified H+-ATPase has the same characteristics. These results show that the H+-ATPase activity is influenced by its phosphorylation. (C) 2002 Elsevier Science B.V. All rights reserved.
