Figure 1.
Figure 1. Electron density maps in the immediate vicinity of the zinc (a,b ) or BH[4] (c,d), contoured at 1.2 (green) and 3.6 (purple). (Left panels) Experimental electron density maps after density modification. (Right panels) 2(F[obs] -F[calc]) electron density maps after refinement. The final model in a ball-and-stick representation is superposed on the maps. a,b Electron density maps in the immediate vicinity of the zinc for iNOS[ox] and eNOS[ox], respectively. The maps clearly define the zinc atom and its coordination. Model colors and orientation as in Fig. 6. c,d Electron density maps in the immediate vicinity of BH[4], iNOS[ox] and eNOS[ox], respectively. All figures were generated using MOLSCRIPT^40 and RASTER3D^41.
