Figure 6.

Upper panel: Active site of the AdSS ternary complex with PLP and IMP (green) overlaid with the active site of the AdSS complex with 6-phosphoryl-IMP (IMO), hadacidin (Had), GDP and Mg2+ (cyan, 6ZXQ) 14. Hydrogen bond network observed in both complexes are shown with dashed green and cyan lines, respectively. Water molecules are represented by spheres (green and cyan, respectively). Mg2+ ion is represented by larger light green sphere. Lower panel: The composite omit electron density map for the ligands in the active site of the AdSS complex with PLP and IMP. The Fo-Fc map is shown, contoured at 3.0 σ level.
