Fig. 6. Run length of a single dynein motor driven by a constant force.

Fig. 6.

The average run length is plotted against the load force on the motor, with each data point representing a measurement of average run length at a fixed force. For an ATP concentration of 500μM (circles), the average run length dropped rapidly to zero at a load force of about 1pN. For ATP concentrations of 1mM (squares), 2mM (diamonds), and 5mM (triangles), when the dynamic catch-bond was activated, the average run length decreased initially, but then reached a minimum at a force of about 1pN before rising again to exhibit another peak and then stalling at a much larger force.
