Pore-forming transmembrane domains control ion selectivity and selectivity filter conformation in the KirBac1.1 potassium channel
Potassium (K(+)) channels are membrane proteins with the remarkable ability to very selectively conduct K(+) ions across the membrane. High-resolution structures have revealed that dehydrated K(+) ions permeate through the narrowest region of the pore, formed by the backbone carbonyls of the signatu...
