Figure 1
Structures of the T2/T3 copper sites in (a) T2D+Cu+ and (b) T2D. The amino-acid residues are shown as ball-and-stick models and are coloured according to atom type. The C atoms of the His residues coordinated to the Cu3α, Cu3β and Cu2 ions are shown in dark green, light green and gold, respectively. The oxygen ligands and copper ions are shown as red and orange spheres, respectively. The 2FoFc electron-density maps (at the 6σ level) for copper ions are shown in blue. Coordination bonds are indicated by black dashed lines.
