FIG. 7. (Color online) The steady-state probability distribution of the two-motor model as a function of a reduced sampling rate ku. At a reduction of ≈0.05 times the initial value, the highest steady-state probability does not belong to the center-positioned intermediate anymore. The distribution turns from a monomodal to a bimodal behavior. The considered system has an ATP concentration of 20μM with a rough approximation for kc and kI and high processivity (see [5]).
