Sodium and potassium competition in potassium-selective and non-selective channels
Potassium channels selectively conduct K(+), primarily to the exclusion of Na(+), despite the fact that both ions can bind within the selectivity filter. Here we perform crystallographic titration and single-channel electrophysiology to examine the competition of Na(+) and K(+) binding within the fi...
