摘要：
The invention provides laccases, polynucleotides encoding these enzymes, theuse of such polynucleotides and polypeptides. In one aspect, the inventionrelates to the enzymatic production of nootkatone by way of the conversion ofvalencene using proteins having a laccase activity, e.g., a novel laccase ofthe invention. In one aspect, the invention provides methods of depolymerizinglignin, e.g., in a pulp or paper manufacturing process, using a polypeptide ofthe invention. In another aspect, the invention provides methods for oxidizingproducts that can be mediators of laccase-catalyzed oxidation reactions, e.g.,2,2-azinobis-(3-ethylbenzthiazoline-6-sulfonate) (ABTS), 1-hydroxybenzotriazole (HBT), 2,2,6,6-tetramethylpiperidin-1-yloxy (TEMPO),dimethoxyphenol, and the like.
