Application
Manganese peroxidase (MnP) is used to oxidize Mn2+ to Mn3+ in the presence of hydrogen peroxide. It is used for the biodegreadation of macromolecular substances such as lignin and humic substances [1].
Biochem/physiol Actions
Manganese peroxidase (MnP) is a hemecontaining glycoprotein that is produced by ligninolytic basidiomycetes. It requires hydrogen peroxide as an oxidant. MnP oxidizes Mn2+ to Mn3+. Mn3+ oxidizes phenolic rings to phenoxy radicals which results in the decomposition of various compounds [1].
Packaging
Bottomless glass bottle. Contents are inside inserted fused cone.
Unit Definition
1 U corresponds to the amount of enzyme which oxidizes 1 μmol Mn2+ to Mn3+ per minute at pH 4.5 and 25°C (in the presence of H2O2).

The direct involvement of manganese peroxidase (MnP) in the mineralization of natural and xenobiotic compounds was evaluated. A broad spectrum of aromatic substances were partially mineralized by the MnP system of the white rot fungus Nematoloma frowardii. The cell-free MnP

We identified a highly expressed protein (BUNA2) by two-dimensional gel electrophoresis from the hyper lignin-degrading fungus Phanerochaete sordida YK-624 under wood-rotting conditions. Partial amino acid sequences of BUNA2 were determined by LC-MS/MS analysis, and BUNA2 gene (bee2) and promoter region
