Manganese peroxidase

Manganese peroxidase is from white-rot fungus (Phanerochaete chrysosporium). It is used to oxidize manganese and catalyzes the oxidation of Mn2+ to Mn3+. Mn3+ is then in complex with oxalate, which is able to oxidize lignin. Manganese peroxidase from Phanerochaete chrysosporium binds 2 calcium ions per subunit. It binds 1 heme B (iron-protoporphyrin IX) group per subunit. One unit of Manganese peroxidase corresponds to the amount of enzyme, which oxidizes 1 μmole Mn²⁺ per minute to Mn³⁺ at pH 4.5 and 25° C
