| Enzyme Function | FUNCTION: Catalyzes the oxidation of Mn(2+) to Mn(3+). The latter, acting as a diffusible redox mediator, is capable of oxidizing a variety of lignin compounds. This isozyme is also able to oxidize phenols and amines in the absence of Mn(2+), similar to versatile peroxidases. {ECO:0000269|Ref.2}. |
