The structure of Cu2+-bound CuBD reveals that the metal ligands are His147, His151, Tyr168 and two water molecules, which are arranged in a square pyramidal geometry. The structure of Cu+-bound CuBD is almost identical to the Cu2+-bound structure except for the loss of one of the water ligands. The geometry of the site is unfavourable for Cu+, thus providing a mechanism by which CuBD could readily transfer Cu ions to other proteins.
