FIGURE 7.

Average angular velocity profiles of the 120° power stroke at 1 mm MgATP. A, average angular velocities of the ATPase-dependent power strokes of MmA₃B₃DF (blue), Gsα₃β₃γ (orange), and Ecα₃β₃γ (black). B, comparison of the angular velocity profile of Ecα₃β₃γ calculated from the arcsine (red) or the arcsine^1/2 (black) functions. Data were collected, and the rotational position was determined as described in Fig. 2. Angular velocities were determined from the moving average of the slope of three consecutive rotational positions from individual power strokes that were averaged and binned for every 3°.
