Kinesin-5 run length as a function of [ATP] and force. Unfilled circles, squares and triangles are simulated data, while filled circles, squares and triangles are experimental data taken from Valentine and Block [15]. (a) Run length versus [ATP] at F_x = 0, F_x = –3 pN and F_x = –3.8 pN. (b) Run length versus F_x at [ATP] = 2 mM and [ATP] = 16 $\mathsf{\mu }\mathrm{M}$.
