Plasma membrane bound ATPase of Vigna sinensis (L) is activated by Mg+2 and is further stimulated by monovalent cations like Na+/K+, at a definite pH and substrate concentration. The true substrate for the enzyme was Mg++‐ATP. Ca++ cannot replace Mg++ so far as the activation of this enzyme is concerned. Activation does not alter much when treated with ouabain. These results support the concept that cation transport at the plasma membrane of root cells of Vigna sinensis (L) is coupled to a cation‐activated ATPase. Malathion (O, O‐dimethyl phosphorodithioate of diethyl mercapto succinate), an organo phosphorus insecticide, activates these enzymes at a concentration of 400 ppm. This increase in activity may be associated with some alteration in the membrane structure, and stimulation by malathion has been found to be of non‐competitive in nature when the divalent and monovalent ions are included in the system
