Figure 1
2Fo − Fc electron-density maps, contoured at 1σ, showing the complexes of DHP with (a) DCP with the Cl atoms shown in green and (b) 5BR with the Br atom shown in purple, (c) the complex of DtpAa with imidazole and (d) the complex of AcNiR with nitrite. In each case, the active site of the monomer with the highest ligand occupancy is shown. The maps in (a)–(d) were generated using the all-image data sets. |
