Effects of viscosity on the appearance and duration of transient dwells. (A) Abundance of n-FoF1 (Δ), n-FoF1-aR210G (), FoF1-cD62G (
), and n-FoF1-a∇14 (
) molecules with transient dwells as a function of PEG400 concentration. (B) Transient dwell duration of n-FoF1 (
), n-FoF1-aR210G (
), and n-FoF1-cD62G (
) as a function of PEG400. (C) Transitions with transient dwells at 15% PEG400 (
) and 30% PEG400 (
) have the same transition time, but different transient dwell durations. Grey lines indicating the power stroke velocity in the presence of 15% PEG400 have the same slope.
