Average values of the relevant parameters estimated by the stochastic model

Estimated Parameters	fast	slow	ratio
f0 (pN)	6.8 ± 1.0	2.4 ± 0.4	2.8
r	0.32 ± 0.02	0.50 ± 0.03	0.64
ϕ (s−1)	6.0 ± 0.2	2.27 ± 0.04	2.6

Average values (mean ± SD obtained by averaging over 6 data records for each isoform) of the three relevant parameters estimated by the stochastic model: the force of a motor, f₀, the fraction of actin–attached motors, r, and the rate of transition through the attachment–detachment cycle, ϕ.
