Left: Experimental mean dwell time <td>, drift velocity v, diffusion coefficient D and fractional current blockade ΔI/Io determined by best fits of dwell time (1D drift-diffusion) and current blockade (Gaussian) histograms. Right: MD simulation results for ΔI/Io. For determination of uncertainties and details on the MD simulations, see Materials and Methods.
