The C-terminal domain of subunit ε of the bacterial Fo F1 ATP synthase is reported to be an intrinsic inhibitor of ATP synthesis/hydrolysis activityin vitro , preventing wasteful hydrolysis of ATP under low-energy conditions. Mutants defective in this regulatory domain exhibited no significant difference in growth rate, molar growth yield, membrane potential, or intracellular ATP concentration under a wide range of growth conditions and stressors compared to wild-type cells, suggesting this inhibitory domain is dispensable for growth and survival ofEscherichia coli .
