Molecular packing in the crystal of Salmonella FlhBC. (a) The asymmetric molecule and symmetry-related molecules are displayed in green and grey, respectively. Sodium ions are represented as magenta spheres and zinc ions are shown as blue spheres. (b) Rotated enlarged view of the zinc-binding site (black box in Fig. 1[link]a). The FoFc electron-density map is displayed in grey at a contour level of 5σ and was calculated without a Zn atom.
