Application
Manganese peroxidase from white-rot fungus (Phanerochaete chrysosporium) is from the peroxidase family and is used to oxidize manganese. It may be used to study wound healing.
Biochem/physiol Actions
Manganese peroxidase 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 .
Unit Definition
One unit corresponds to the amount of enzyme, which oxidizes 1 μmole Mn2+ per minute to Mn3+ at pH 4.5 and 25 °C
Physical form
Supplied as a lyophilized powder containing ~50% sodium tartrate
only partially soluble in water or buffer
Other Notes
This product is supplied as a mixture of isozymes, mol. mass (40-65 kDa).
