Protein

Laccase

Gene

LCC3-1

Organism
Pycnoporus cinnabarinus (Cinnabar-red polypore)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein leveli

Functioni

Most probably plays an important role in lignin degradation. Cleaves the C-C and C-O bonds of some phenolic lignin model compounds (such as O- and P-quinols, aminophenols and phenylenediamine). May also be involved in synthesis of phenoxazinone pigments.

Catalytic activityi

4 benzenediol + O2 = 4 benzosemiquinone + 2 H2O.

Cofactori

Binds 4 copper ions per monomer.By similarity
