Effects of ATP concentrations that limit the rate of ATPase activity on the average angular velocity profiles. A, dwell abundance as a function of rotational position during the power stroke of Ecα₃β₃γ at 1 mm MgATP (black) versus 0.3 mm MgATP (red). B, dwell abundance as a function of rotational position during the power stroke of the MmA₃B₃ complex at 1 mm MgATP (blue) versus 0.1 mm MgATP (red). C, average angular velocity profile of the Ecα₃β₃γ power stroke at 1 mm MgATP (black) versus 0.3 mm MgATP (red). D, average angular velocity profile of the MmA₃B₃DF power stroke at 1 mm MgATP (blue) versus 0.1 mm MgATP (red).
