The conduction pathway of potassium channels is water free under physiological conditions. [PDF]
, 2019 Ion conduction through potassium channels is a fundamental process of life. On the basis of crystallographic data, it was originally proposed that potassium ions and water molecules are transported through the selectivity filter in an alternating ...
