“Operating principles of rotary molecular motors:
differences between F₁ and V₁ motors”

【Significance】
Molecular rotation mechanism of rotary motors

V- and F-ATPases are unique molecular rotary motors among many types of bioenergy-transducing machineries. We recently reported the crystal structures of the bacterial V_1-ATPase, corresponding to an intermediate state of waiting for ATP hydrolysis in the catalytic cycle. Rotary dynamics and torque generation of same V_1-ATPase have also been revealed. Based on these results of crystal structures and single-molecule observations, we present a novel V_1-ATPase rotational mechanism model that is apparently different from that of F_1-ATPases.
