Potassium channel selectivity filter dynamics revealed by single-molecule FRET

Potassium (K) channels exhibit exquisite selectivity for conduction of K(+) ions over other cations, particularly Na(+). High resolution structures reveal an archetypal selectivity filter (SF) conformation in which dehydrated K(+), but not Na(+), ions are perfectly coordinated. Using single molecule...
