Ion copper in the oxidized state 2 + is localized at one end of the molecule, 6 Å below the surface. The copper atom is in the core of a hydrophobic patch composed of residues His-37, Cys-84, His-87 and Met-92. This copper binding site has a distorted trigonal pyramidal shape. The base of the pyramide is composed of one sulfur from a cysteine and two nitrogen atoms from two different histidins and the apex is formed by one sulfur from a methionin. The distortion occurs on the bond between the copper and the sulfur atom. | Ion copper in the oxidized state 2 + is localized at one end of the molecule, 6 Å below the surface.
