CC   -!- FUNCTION: Lignin degradation and detoxification of lignin-derived
CC       products (By similarity).
CC   -!- CATALYTIC ACTIVITY: 4 benzenediol + O(2) = 4 benzosemiquinone + 2
CC       H(2)O.
CC   -!- COFACTOR: Binds 4 Cu-ions per molecule. Three distinct Cu centers
CC       known as type 1 or blue, type 2 or normal, and type 3 or coupled
CC       binuclear (By similarity).
CC   -!- SUBCELLULAR LOCATION: Secreted.
CC   -!- PTM: N-glycosylated at Asn-467; contains a high-mannose glycan
CC       with a varying number of mannose residues.
CC   -!- MISCELLANEOUS: POX2 isozyme is the most abundant laccase of
CC       P.ostreatus under various growth conditions.
CC   -!- SIMILARITY: Belongs to the multicopper oxidase family.
CC   -!- SIMILARITY: Contains 3 plastocyanin-like domains.
