Envisaged properties of kinesin mechanochemical coupling. (a) The enzymatic rate of ATP catalysis (blue), Michaelis-Menten constant (dark red) and coupling efficiency (red). (b) The randomness parameter for mechanical (closed symbols) and chemical (open symbols) reactions at [ATPsat] (black) and [ATPlim] (purple). Each curve is calculated using the parameters from Table 1 and equations (2)–(7). Plots are calculated from those in Figs. 2 and 3.
