WebMechanism of the F 1 ATP-ase . The ATP synthase operates through a mechanism in which the three active sites undergo a change in binding affinity for the reactants of the ATP-ase reaction, ATP, ADP and phosphate, as originally predicted by Paul Boyer. WebMay 31, 2000 · Abstract. The F (0)F (1) ATP synthase functions as a rotary motor where subunit rotation driven by a current of protons flowing through F (0) drives the binding changes in F (1) that are required for net ATP synthesis. Recent work that has led to the identification of components of the rotor and stator is reviewed.
WebThe steps in the binding change mechanism are as follows: F(0)F(1) ATP synthase acts as a rotary motor, with protons assisting in the spin movement of the subunits that make up the α and β subunits.; The release of ATP is caused by the rotation of the γ subunit.; The complex comprises three conformations: open ("O"), loose ("L"), and tight ("T").
