Concept of the duration time of the interaction between one actin filament and several HMM molecules. (A) Schematic diagram of the experiment. (B) Scheme of the interaction between one actin filament and N HMM molecules, with an association rate constant p and dissociation rate constant q. (C) Simultaneous differential equation of the Nth order for the duration time of the actomyosin interaction. P_i(t) is the probability at time t that i HMM molecules interact with the actin filament at the same time.
