Figure 6.

Gating current fluctuations with multiple gating charges on the voltage sensor. (A) Variance-mean current plots obtained in simulations performed with the simplified model, with four gating charges on the voltage sensor (charge density was normally distributed with an SD of 1 Å). The three plots correspond to different intercharge distances (indicated). The insets in each plot show the corresponding gating charge distribution. (B) Plots of the radius, electrical, chemical, and total energy profiles for the simulation shown in (A), with an intercharge distance of 8 Å. (C) Plot of the apparent charge estimated from simulations performed at different intercharge distances. To see this figure in color, go online.
