Pore mutations in Shaker K+ channels distinguish between the sites of tetraethylammonium blockade and C-type inactivation.
1. We have studied the effect of external K+ and tetraethylammonium (TEA) on several mutants of Shaker B K+ channels with amino acid substitutions in the pore which alter TEA affinity and the rate of C-type inactivation. In all channels studied high external K+ makes C-type inactivation slower. 2. I...
