Potassium and sodium ion complexes with a partial peptide of the selectivity filter in K channels studied by cold ion trap infrared spectroscopy: the effect of hydration

Potassium channels allow K + to rapidly diffuse, while the selectivity filter (SF) actively blocks Na + . The presence of water in the SF during ion translocation remains under debate due to the experimental and computational challenges in characterizing the interactions between water, ions, and the...
