Abstract The chloroplast ATP synthase is strictly regulated so that it is very active in the light (rates of ATP synthesis can be higher than 5 μmol/min/mg protein), but virtually inactive in the dark. The subunits of the catalytic portion of the ATP synthase involved in activation, as well as the effects of nucleotides are discussed. The relation of activation to proton flux through the ATP synthase and to changes in the structure of enzyme induced by the proton electrochemical gradient are also presented. It is concluded that the γ and ε subunits of CF1 play key roles in both regulation of activity and proton translocation.
