Figure 4

A. Schematic representation of the bi-metallic centre of OPHC2. The two metals and the two water molecules are represented as grey balls. B. Three dimensional representation of the OPHC2 active site cavity. Residues are shown as sticks. The metal coordination sphere is shown as dashed lines. The disulphide bridge between Cys110 and Cys146 is colored in yellow. The leaving group subsite of OPHC2 is colored in purple, and the two side pockets are colored in green and blue.
