Mechanism of potassium channel selectivity revealed by Na(+) and Li(+) binding sites within the KcsA pore
Potassium channels allow K(+) ions to easily diffuse through their pores while effectively preventing smaller Na(+) ions from permeation. The ability to discriminate between these two similar and abundant ions is vital for these proteins to control electrical and chemical activity in all organisms....
