Manganese peroxidase (MnP) catalyzes the conversion of Mn+2 to Mn+3 using hydrogen peroxide. MnP contains a heme group and needs calcium ion for activity. MnP is involved in lignin degradation. MnP is produced by wood-rotting fungi. Mn+3 in a chelated form is a powerful oxidizing agent which is able to mineralize lignin to CO2.
