Lignin degradation and detoxification of lignin-derived products (Probable). Oxidation of a broad range of substrates including mono-, di- and polyphenols, aromatic amines and methoxy-substituted phenols accompanied by reduction of oxygen to water. 4 hydroquinone + O2 = 4 benzosemiquinone + 2 H2O Binds 4 Cu cations per monomer. Inhibited by sodium azide. Optimum pH is 3.8 with 2,6-dimethoxyphenol as substrate, and less than 2.7 with ABTS as substrate. Optimum temperature is 50 degrees Celsius. Half-life at 60 degrees Celsius is 20 minutes. Half-life at 70 degrees Celsius is 3 minutes. Monomer. By copper ions. Glycosylated; contains 6% carbohydrates. On the 2D-gel the determined pI of this protein is: 3.85, its MW is: 67 kDa. Belongs to the multicopper oxidase family. The order of the peptides is unknown.
