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 .
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 .
Packaging
Bottomless glass bottle. Contents are inside inserted fused cone.
Other Notes
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).
