Table 1.

Angular/rotational diffusion constant calculated from MSD.

Condition	D (rad2/s)
θ without ATP	5.7 × 10−6
θ with ATP	6.9 × 10−6
χ without ATP	6.4 × 10−6
9.0 × 10−6	χ with ATP

The values were obtained from the slope of the MSD versus time plot shown in Figure 2. The lines in Figure 2B were fitted with least-squares fitting to the following equation, MSD = 4Dt + a, where MSD is the mean square angular displacement, D is the angular/rotational diffusion constant, t is time interval, and a is intercept.
