The electron density surrounding the Ni2+ ion in the crystal structure of cce_0567 illustrated at 1.5 σ. The N2 ring nitrogen from the histidine-36 side chain of two molecules coordinate the Ni2+ with water occupying the other sites around the metal. In the diagram on the right, H36′ has been rotated ~90° about the z-axis into the plane of the paper.
