Figure 1

Active sites of the (A) ethylamine- and (B) benzylamine-containing HPAO-1 complexes. Residues and substrate species from polypeptide chain D of both structures are drawn in stick and colored by atom type (carbon, grey). Water molecules are drawn as small red spheres and copper ions are drawn as gold spheres. Hydrogen bonds are indicated by dashed lines, and metal-ligand interactions are indicated by solid lines. Electron density from the 2Fo-Fc electron density maps contoured at 1σ is drawn as blue mesh.
