Estimates of the magnitude of CheY-P fluctuation in a model-independent way. (A and B) Fits of the CCW-interval-versus-CW bias and CW-interval-versus-CW bias data for the mutant using the equations T+ = τD/B and T− = τD/(1-B), respectively, with the fitted parameter τD = 0.11 s. (C) A fit of the mean CCW-interval-versus-CW bias data for the wild-type with the fitted parameter σY = 0.21 ± 0.05 μM. (Circles) Data points; (lines) fits.
