Figure 7.

Radial pair distribution functions showing the probability distribution $g\left(r\right)$ of two atoms lying at a given radius r for contacts between ChTX and the channel. Both curves have been normalized to have a maximum value of one. The solid line shows $g\left(r\right)$ between the HH12 atom of ChTX Arg-25 and the OC atom of Asp-379, and the broken line is $g\left(r\right)$ between the HH11 atom of ChTX Arg-34 and O of Asp-379.
