General annotation (Comments)

Function	Lignin degradation and detoxification of lignin-derived products By similarity.
Catalytic activity	4 benzenediol + O2 = 4 benzosemiquinone + 2 H2O.
Cofactor	Binds 4 copper ions per monomer By similarity.
Subcellular location	Secreted › extracellular space › apoplast Potential.
Sequence similarities	Belongs to the multicopper oxidase family. Contains 3 plastocyanin-like domains.
Sequence caution	The sequence AK103094 differs from that shown. Reason: Frameshift at position 318. The sequence EAZ19043.1 differs from that shown. Reason: Erroneous gene model prediction.
