Enzyme Commission Summary for
A hemoprotein. The enzyme from white rot basidiomycetes is involved in the oxidative degradation of lignin. The enzyme oxidizes a bound Mn2+ ion to Mn+3 in the presence of hydrogen peroxide. The product, Mn+3, is released from the active site in the presence of a chelator (believed to be oxalate) that stabilizes it against disproportionation to Mn2+ and insoluble Mn4+ [Kuan93]. The complexed Mn+3 ion can diffuse into the lignified cell wall, where it oxidizes lignin and other organic substrates [Glenn86].

Enzyme Commission Summary for
This ligninolytic peroxidase combines the substrate-specificity characteristics of the two other ligninolytic peroxidases, EC, manganese peroxidase and EC, lignin peroxidase. It is also able to oxidize phenols, hydroquinones and both low- and high redox-potential dyes, due to a hybrid molecular architecture that involves multiple binding sites for substrates [Heinfling98, Camarero99].
