Figure 6
Structure of the T1 copper site in (a) BaL and (b) L499M BaL. The 2Fo − Fc electron-density maps for the axial residues are shown at the 1σ level. The amino-acid residues are displayed as ball-and-stick models and are coloured according to atom type. The copper ions are represented by orange spheres. The coordination bonds at the Cu1 ion are indicated by black dashed lines. The weak coordination bond between Met499 Sδ and Cu1 is shown in purple with the bond length on the right.
