f1fo-ATP synthase catalyzes the final step of oxidative phosphorylation, the synthesis of ATP from ADP and phosphate, driven by a transmembrane proton gradient. In bacteria, under certain physiological conditions, the enzyme can also hydrolyze ATP to generate a proton gradient. ATP synthesis/hydrolysis and proton translocation are coupled in a unique way, via subunit rotation. While our knowledge of the molecular basis of ATP hydrolysis and its integration with rotation is still far from complete, it is much better understood than ADP phosphorylation because it is easier experimentally accessible
