pH sensitivity of WT and mutant channels. pK (Upper) and percentage inhibition (Lower) at pH 6.8 relative to pH 8.8 for WT and mutant channels. Numbers on abscissa correspond to amino acid number. The number of determinations for each channel is given in brackets. *, Statistical significance compared with WT (P < 0.05).
