The Barium Site in a Potassium Channel by X-Ray Crystallography
X-ray diffraction data were collected from frozen crystals (100°K) of the KcsA K(+) channel equilibrated with solutions containing barium chloride. Difference electron density maps (F(barium) − F(native), 5.0 Å resolution) show that Ba(2+) resides at a single location within the selectivity filter....
