Abstract excerpt

K+ plays an important role for the function of the sarco(endo)plasmic reticulum Ca2+ -ATPase (SERCA), but its binding site within the molecule has remained unidentified. We have located the binding site for a K+ ion in the P-domain by means of x-ray crystallography using crystals prepared in the presence of the K+ congener Rb+. Backbone carbonyls from the loop containing residues 711-715 together with the side...
