Description générale

We are committed to bringing you Greener Alternative Products, which adhere to one or more of The 12 Principles of Greener Chemistry. This product has been enhanced for energy efficiency and waste prevention when used in fuel cell and cellulosic ethanol research. For more information see the article in biofiles and Enzymes for Alternative Energy Research

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.

Actions biochimiques/physiologiques

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 .

Définition de l'unité

One unit corresponds to the amount of enzyme, which oxidizes 1 μmole Mn2+ per minute to Mn3+ at pH 4.5 and 25 °C

Forme physique

Supplied as a lyophilized powder containing ~50% sodium tartrate
only partially soluble in water or buffer

Autres remarques

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