Behaviors of ACPs between unbinding and rebinding events. (A) Distance of travel between unbinding and rebinding (solid circles) and the average turnover, indicating whether or not ACP rebinds to the same filament after unbinding (open circles). The turnover value of 1 indicates rebinding to a different filament, whereas a turnover value of 0 indicates rebinding to the same filament. (B) An example showing displacement and turnover of ACPs unbound with ≥20 pN during shearing of the system from γ = 0 (dashed line) to γ = 1 (solid line). On the xz plane, lines are drawn between unbinding and rebinding locations, with the open and solid symbols indicating rebinding to different or the same filaments, respectively.
