F 1-ATPase (F 1) is a rotary motor protein in which the rotor γ subunit rotates in the α 3β 3 ring hydrolyzing adenosine-5′-triphosphate (ATP). Several fluctuation theories of nonequilibrium statistical mechanics have been applied recently to the single-molecule experiments on F 1. For example, the fluctuation theorem, a recent achievement in the field of nonequilibrium statistical mechanics, has been suggested to be useful for measuring the rotary torque of F 1. In this paper, we introduce F 1 as a good biological model for experimentally testing the theories of nonequilibrium statistical mechanics.
