Figure 4
Panel A shows the damage occurring at residues involved in the salt-bridge clusters [cluster 1 (Glu 247 and Asp 65), cluster 2 (Asp 209) and cluster 3 (Asp 211 and Glu 188); Richard et al., 2000]. Panel B shows the damage of residues involved in interactions with the hydroxyl group of Ser, Tyr or Thr residues. The amino acids are shown as sticks (grey, monomers A and C; copper, monomers B and D). The difference electron density maps (Fo 3-Fo 1, negative contours in red and positive contours in green drawn at ± 3.5σ) are overlaid on the reference model 1. |
