Figure 8. — (A) I-V relationships for homotetramers and heterotetramers of KcsA. Diamonds, WT₄; squares, WT₃E71A₁; triangles, WT₂E71A₂; circles, WT₁E71A₃; crosses, E71A₄. Each data point represents the mean ± SD from at least four separate bilayers. (B) Unitary conductance values of WT/E71A heteromers at −100 mV. Each data point represents the mean ± SD from at least 11 separate bilayers. The measurements were done in 200 mM KCl, buffered with 10 mM HEPES, pH 7.0, in the cis chamber and 200 mM KCl, buffered with 10 mM succinic acid, pH 4.0, in the trans chamber.
