Hill parameters for WT and R95C actin filaments

Each parameter ± S.E. was determined by fitting the data presented in Fig. 8 to the Hill equation. Shown here is a representative of three independent measurements.

	Velocity			Filaments moving at uniform speeds
	WT	Mutant	Cofilament	WT	Mutant	Cofilament
Hill coefficient	1.6 ± 0.70	1.5 ± 0.28	2.5 ± 0.54	2.7 ± 0.63	2.0 ± 0.14	3.5 ± 0.94
pCa50	6.6 ± 0.09	6.9 ± 0.06	6.8 ± 0.03	6.6 ± 0.04	6.9 ± 0.02	6.7 ± 0.04
Vmax (μm/s)	3.9 ± 0.38	5.1 ± 0.27	4.3 ± 0.14
Fmax (%)				74 ± 4.1	95 ± 1.8	82 ± 4.7
