powder, light brown, ≥20 U/g

Synonym: Manganese-dependent lignin peroxidase, MnP, Peroxidase, manganese

Description

Other Notes

This product is supplied as a mixture of isozymes, mol. mass (40-65 kDa).

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

only partially soluble in water or buffer

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 healing1.

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 1.
