Metal Preferences of Zinc-Binding Motif on Metalloproteases

Figure 3

Molecular modeling of the catalytic site of rat DPP III. The model was generated as a template of the human DPP III crystal structure [39]. The zinc ion is shown as a green sphere, and amino acid side chains are shown as sticks colored red for oxygen, blue for nitrogen, and white for carbon. Metal coordinates in light blue and hydrogen bonds in yellow are indicated by dashed lines.
