Figure 4.
Current–voltage plots (I–V plots) are shown in the lower right panel. Single-channel conductances (slopes of the linear fit obtained from SigmaPlot, version 9.2) were 44.5 pS for WT (•), 114 pS for F23A (▪), 77 pS for V25F–A32F (▾), 10 pS for N15A–V25F (△). The data represents the average from 4 to 10 recordings.
