Figure 3. Figure 3. (a) Stereoview of the zinc ligands in the metal-binding site. Dashed lines indicate the strong zinc–ligand interactions. (b) Stereoview of the electron density contoured at 1.5 σ level. This view emphasizes the bidendate character of the Zn2– carboxylate interaction with Asp179. A similar interaction is observed between Glu152 (not labeled) and Zn1. Figure 3. (a) Stereoview of the zinc ligands in the metal-binding site.
