Figure 7
A stereoview of the Cu and Zn sites in two monomers of bovine Cu-Zn SOD 1.65 Å resolution structure. Monomer a (top) is clearly tri-coordinate showing a clear break between Cu and His 61 while monomer b (bottom) shows this bond intact and a well defined water density at the Cu site. Cu and Zn molecules are shown as yellow and blue spheres, respectively. A water molecule is shown as a smaller blue sphere. |
