ATP synthesis by F-type ATP synthases consumes energy stored in a transmembrane electrochemical gradient of protons or sodium ions. The electric component of the ion motive force is crucial for ATP synthesis. Here, we incorporate recent results on structure and function of the F(0) domain and present a mechanism for torque generation with the fundamental nature of the membrane potential as driving force in the core.
