Selectivity in K(+) channels is due to topological control of the permeant ion's coordinated state
The selectivity filter of K(+) channels provides specific coordinative interactions between dipolar carbonyl ligands, water, and the permeant cation, which allow for selective flow of K(+) over (most importantly) Na(+) across the cell membrane. Although a structural viewpoint attributes K(+) selecti...
