Figure 5.

Time courses of polystyrene bead rotation at 2 mM MgATP. (A–C) Rotation of 0.29-μm bead duplexes attached to the WT (A), the β-γ fusion (B), and the protrusionless mutant (C). Note the difference in the vertical scales. (D–F) 0.49-μm bead duplexes. Time-averaged rotary speeds were estimated on uninterrupted portions (see text for the protrusionless mutant) and are plotted in Fig. 4B as small dots. To see this figure in color, go online.
