Figure 1
Cross section of the cylindrical channel used in the comparisons (top). The length of the channel is 35 Å, including the rounded corners, which have a radius of 5 Å. The dielectric constants are 80 in the channel and 2 in the protein. An electric field of E = 107 V/m is applied as indicated by the arrow. The dotted lines show the layers used in the concentration plot below. (A) Concentration profiles of Na+ ions in a 4-Å radius channel as predicted from PNP theory (•) and BD simulations (histograms). The shaded areas indicate the reservoir values. (B) Conductance of ions, normalized by the cross-sectional area, are plotted against the channel radius. The results obtained from the BD simulations (•, Na+; ○, Cl−) are fitted by the dotted lines. The PNP results are shown by the solid lines.
