F1 ATPase contains three catalytic β subunits that hydrolyze ATP, causing the central γ subunit to rotate. Now, using fluorescent tags, conformational changes in β and rotation of γ are observed simultaneously within the same complex, allowing the motions in β to be correlated with catalytic events and ultimately rotation.
