Water molecules found in close contacts because of two reasons. 1) Being a part of the coordination sphere of Ca2+ ions, possibly in different configurations, could not be fully resolved. 2) Some water molecules are in contact with the phosphate moieties of the DNA, with some contact angles close to 90 degrees, suggesting these may be Mg2+ or Na+ ions - these were modelled as water molecules, because there were no sodium or magnesium salts present during purification and crystallization.
