Figure 5 Structure of the sodium-binding site in the native
crystal (a) and the transformed crystal (b). The water molecule
in the native crystal is replaced by a sodium ion in the
transformed crystal. In molecule 1 a nitrate anion is directly
coordinated, but in molecule 2 a nitrate ion is bound by
water-mediated hydrogen bonds.
