Figure 1
(a) Nickel site I and (b) nickel site II in the 1.50 Å resolution Ni insulin structure. Ni2+ is hexacoordinated by three HisB10 residues and three water molecules (red) coordinating to Ni in both sites. Distances to the first coordination sphere as determined by single-crystal X-ray diffraction are shown. The σA-weighted 2Fo − Fc maps are contoured at 1.0σ. |
