General description

Manganese peroxidase from white-rot fungus (Phanerochaete chrysosporium) is a lignin-modifying peroxidase that catalyzes the oxidation of Mn2+ to Mn3+. Mn3+ is stabilized by chelators like oxalic acid. Manganese peroxidase uses peroxide as an oxidant and manganese coordination compounds as charge-transfer mediators.

Manganese peroxidase has a molecular weight of 40-50 kDa and is a glycosylated heme protein.

Unit Definition

One unit is the amount of enzyme which will oxidize 1.0 μmole Mn2+ per minute to Mn3+ at pH 4.5 and 25 °C

Physical form

Supplied as a lyophilized powder containing ~50% sodium tartrate
