Selectivity filter mutations shift ion permeation mechanism in potassium channels
A. Mironenko, B. L. de Groot, W. Kopec
The paper uses molecular dynamics simulations to show that mutations in the selectivity filter of KcsA channels shift the ion permeation mechanism from water-free to co-permeation of K+ and water, reducing conductance and selectivity.
