Abstract

The enzymatic reactions of the blue copper oxidase, Rhus laccase are discussed and the importance of dioxygen intermediates coordinated to the type 3 copper site in laccase is demonstrated. Based on the experimental evidence discussed in the paper a reaction scheme for laccase is given which requires O2 reduction through the successive stages \(O_2^ - \to O_2^{2 - } \to \left( {{O^{2 - }} + {O^ - }} \right)\) with laccase molecules reduced to different extents. Intermediates with these dioxygen species coordinated to copper have either been identified or are required by the kinetic data. Isolation of a peroxide coordinated laccase intermediate in the reoxidation of the half reduced enzyme with O2 is especially noteworthy. The 0-0 bondbreaking step is shown to involve cooperation between the type 2 and type 3 sites. Conformational changes controlling the relative rates of different steps have been detected and are discussed.
