The epsilon subunit, a small subunit located in the F1 domain of ATP synthase and comprising two distinct domains, an N-terminal beta-sandwich structure and a C-terminal alpha-helical region, serves as an intrinsic inhibitor of ATP hydrolysis activity. This inhibitory function is especially important in photosynthetic organisms as the enzyme cannot synthesize ATP in the dark, but may catalyse futile ATP hydrolysis reactions ...
