The structure of bovine mitochondrial F1-ATPase: an example of rotary catalysis.
There is now compelling evidence in support of a rotary catalytic mechanism in F1-ATPase, and, by extension, in the intact ATP synthase. Although models have been proposed to explain how protein translocation in F0 results in rotation of the gamma-subunit relative to the alpha 3/beta 3 assembly in F1 [22], these are still speculative. It seems likely that a satisfactory explanation of this mechanism will ultimately depend on structural information on the intact ATP synthase.
