From: Simulating a chemically fueled molecular motor with nonequilibrium molecular dynamics
For a fixed NESS with \({\mu }_{{{{{{{{\rm{FTC}}}}}}}}}^{\prime}=0.5\), \({\mu }_{{{{{{{{\rm{ETC}}}}}}}}}^{\prime}={\mu }_{{{{{{{{\rm{C}}}}}}}}}^{\prime}=-10\) (corresponding to 〈NFTC〉 = 8.6, 〈NETC〉 = 0.1, and 〈NC〉 = 0.9), clockwise bias (a), current (b), and coupling (c) were analyzed from simulations with variable friction coefficient γ. Reported data are the means and standard errors of 50 independent simulations of tobs = 1 × 106 units of time each. As the friction increases, the overall rates all decrease, causing some high-friction simulations to have no cycles in either direction. Those trials were excluded from the clockwise bias statistics, but were still included in the calculation of the current and the net cycles per catalyzed reaction.
