additional information
a cadmium ion from the crystallization buffer binds to the proposed nickel-binding site and is penta-coordinated by Glu16, Asp62, His93, and a water molecule in a pseudo-tetragonal arrangement. HYBD is topologically related to members of the metzincins superfamily of zinc endoproteinases, sharing the central beta-sheet and three helices. In contrast to the metzincins, the metal-binding site of HYBD is localized at the C-terminal end of the beta-sheet
