Fig. 7. ATP-induced dissociation of acto-S1.

Fig. 7

A, dependence of kobs on ATP concentration calculated from the increase in fluorescence when 0.25 μM pyrene-labeled acto-S1 was mixed with ATP; data were fit to the Michaelis-Menten equation. B, kobs at low ATP concentrations. The slopes of the curves give the second order rate constants, K1′k+2′ (Table II).
