Figure 1
Structures of the Mg-containing water cluster and Asp50-Asp51(I) for the oxidized crystals at pH 7.3 and pH 5.7, and the reduced crystal at pH 5.7, are shown as close-up views (boxes). Amino-acid residues are shown as sticks. Their N atoms are coloured blue, and C atoms of the oxidized crystals at pH 7.3 and pH 5.7 are coloured pink and yellow, respectively. The amino-acid residues of both oxidized crystals superpose well on each other. Residues of the reduced crystal at pH 5.7, drawn as thin black sticks, differ structurally from the residues of the oxidized crystals. The green and brown spheres are Mg and Cu ions, respectively. The red and blue spheres are waters belonging to the oxidized crystals at pH 5.7 and pH 7.3, respectively. Glu198(II) bridging the CuA and Mg ions changes its coordination angle to the Mg ion upon redox change. |
