Protein

Laccase-2

Gene

LAC2

Organism
Podospora anserina (Pleurage anserina)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at transcript leveli

Functioni

Probably involved in lignin degradation and in the detoxification of lignin-derived products in its natural habitat (herbivorous dung), which is rich in lignin of grasses and straw. Probably involved in melanin synthesis and in perithecia development.

Catalytic activityi

4 benzenediol + O2 = 4 benzosemiquinone + 2 H2O.

Cofactori

Binds 4 copper ions per monomer.By similarity
