Figure 2
7k3t anomalous density map, contoured at 4σ. Anomalous density is only present in the asymmetric unit above 4 σ in the vicinity of the active site (as shown here). Both Zn2+ alternate conformations modeled in 7k3t display tetra­hedral coordination geometry, as shown with black dotted lines.
