Function
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[1]. Ceriporiopsis subvermispora expresses 3 genes of MnP: a short, long and extralong.
Relevance
Mn+3 in a chelated form is a powerful oxidizing agent which is able to mineralize lignin to CO2.
