Abstract

Isolated thylakoid membranes have a high rate of ATP synthesis but only very low rates of ATP hydrolysis and Pi-ATP exchange [I]. Enhanced rates of ATP hydrolysis and Pi-ATP exchange can be obtained without affecting the rate of ATP synthesis by energization of the membranes in the presence of thiol reagents [2, 3]. Illumination of the membranes for several minutes* elicits maximal ATPase and Pi-ATP exchange activities [2, 3] while lower than maximal activities are obtained by energization with short light flashes [4], short …
