摘要
The F0F1 ATP synthase functions as a rotary motor where subunit rotation driven by a current of protons flowing through F-0 drives the binding changes in F-1 that are required for net ATP synthesis. Recent work that has led to the identification of components of the rotor and stator is reviewed. In addition, a model is proposed to describe the transmission of energy from four proton transport steps to the synthesis of one ATP. Finally, some of the requirements for efficient energy coupling by a rotary binding change mechanism are considered. (C) 2000 Elsevier Science B.V. All rights reserved.
