Two Stable, Conducting Conformations of the Selectivity Filter in Shaker K(+) Channels
We have examined the voltage dependence of external TEA block of Shaker K(+) channels over a range of internal K(+) concentrations from 2 to 135 mM. We found that the concentration dependence of external TEA block in low internal K(+) solutions could not be described by a single TEA binding affinity...
