Abstract
Plasma membrane vesicles isolated from com roots were shown to possess Mg2+-dependent and K+-stimulated ATPase activity, which was inhibited by vanadate, insensitive to nitrate and molybdate, and very little se nsitive to azide. The optimum of phosphohydrolase activity was at pH 6 .5 and temperature optimum 40-degrees-C. ATP was the preferred substra te. The Plasma membrane ATPase was reconstituted into soybean phosphol ipid liposomes.
