F1-ATPase is a nano-sized rotary motor protein in which three catalytic β-subunits in a stator α3β3 ring carry out sequential and cooperative ATP hydrolysis reactions and large conformational changes to rotate the rotor γ-subunit unidirectionally. In contrast to other motor proteins, F1-ATPase shows reversible, nearly 100% chemo-mechanical energy conversion efficiency, and synthesizes ATP upon forced reverse rotation. I will introduce our recent results obtained by single-molecule techniques based on optical microscopy and high-speed atomic force microscopy. I will also discuss the possible operation mechanism behind the F1-ATPase, along with structurally-related hexameric ATPases, also mentioning the possibility of generating hybrid nanomotors.
