F, a water-soluble domain, can catalyze both the synthesis and hydrolysis of ATP with the rotation of the central rotor inside a cylinder made of in three different conformations (referred to as , , and ). In this study, we determined multiple cryo-electron microscopy structures of bacterial FF exposed to different reaction conditions. The structures of nucleotide-depleted FF indicate that the ε subunit directly forces to adopt a closed form independent of the nucleotide binding to . The structure of FF under conditions that permit only a single catalytic subunit per enzyme to bind ATP is referred to as unisite catalysis and reveals that ATP hydrolysis unexpectedly occurs on instead of , where ATP hydrolysis proceeds in the steady-state catalysis of FF. This indicates that the unisite catalysis of bacterial FF significantly differs from the kinetics of steady-state turnover with continuous rotation of the shaft. | |||||||||||||||
