Abstract
The effect of low-intensity irradiation of a helium-neon laser on the hydrolytic activity of the vacuolar membrane proton pumps has been stu died. The maximum effect was found for the 3 min irradiation from a cl ose distance (0.3 m); moreover, the PPase activity increased by 33%, w hereas the ATPase activity was inhibited by 44%. The effect described is suggested to be due to different conformations of the enzymes in th e membrane and their different physiological roles.
