Paul D. Boyer developed a binding-change mechanism for ATP synthase. Different conformations of catalytic sites bind substrates, form ATP, and release it at different stages of the cycle.
This connects mechanical coupling with catalysis: rotation changes the state of a catalytic site rather than requiring an identical chemical environment at every moment.[ref]
