Fig. 3.
The characteristic rupture force of actomyosin bonds over a range of loading rates. At higher loading rates, actomyosin–ADP bonds (●) appear to be stronger than rigor bonds (○). Corresponding data from single-headed HMM in each state (♦, ◇) are superimposed. The dashed line indicates the rigor behavior predicted from step load data (see text). Error bars represent SEM.
