Figure 5
Density found in the active site of AtzA. A composite OMIT map was generated using the CCP4 package and the figure shows the `extra' density seen in the active site which may be owing to atrazine (top of the figure, blue mesh). The active-site iron is shown as an orange sphere, water is shown as a red sphere and several active-site residues are shown with associated density. The OMIT map was set to 1σ. |
