Manganese peroxidase Manganese peroxidase In enzymology, a manganese peroxidase () is an enzyme that catalyzes the chemical reaction The 3 substrates of this enzyme are Mn(II), H, and HO, whereas its two products are Mn(III) and HO. This enzyme belongs to the family of oxidoreductases, to be specific those acting on a peroxide as acceptor (peroxidases). The systematic name of this enzyme class is Mn(II):hydrogen-peroxide oxidoreductase. Other names in common use include peroxidase-M2, and Mn-dependent (NADH-oxidizing) peroxidase. It employs one cofactor, heme. This enzyme needs Ca for activity. White rot fungi secrete this enzyme to aid lignin degradation. Manganese peroxidase (commonly referred
Manganese peroxidase the presence of O, can oxidize lignin or react with water to form HO. The Mn3+ ion itself can degrade lignin by catalyzing alkyl-aryl cleavages and α-carbon oxidation in phenols. MnP activity is controlled via transcriptional regulation. MnP is up-regulated by increases in extracellular Mn(II) and HO concentrations. It has been found that increased O concentration and heat stress also activate MnP.
