K(+) versus Na(+) ions in a K channel selectivity filter: a simulation study.

K(+) versus Na(+) ions in a K channel selectivity filter: a simulation study.

Molecular dynamics simulations of a bacterial potassium channel (KcsA) embedded in a phospholipid bilayer reveal significant differences in interactions of the selectivity filter with K(+) compared with Na(+) ions. K(+) ions and water molecules within the filter undergo concerted single-file motion...
