[The effect of photoexcitation of the electron shell of calcium and magnesium atoms on the ATPase activity].

Influence of visible light on Mg-ATPase and Ca-ATPase activity of thymocytes plasma membranes was investigated. It has been shown that illumination of the membranes at lambda = 518 nm 1.8 times increased Mg-ATPase activity and illumination at lambda = 445.5 nm 1.9 times increased Ca-ATPase activity.
