The V121T mutation prevents inactivation of E132Q in 100 mM K (red dashed line versus black line with triangles) without significantly altering the pKa during acidification (brown dashed line versus black line with squares). Internal oocyte pH was controlled with permeant acetate buffers. External K was maintained constant at 100 mM, and whole-cell conductances were normalized to their maximal values.
