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(II) oxide mostly for demonstration purposes, is the oxalate method, which also applicable to the synthesis of ferrous oxide and stannous oxide. Upon heating in an oxygen-free atmosphere (usually CO), manganese(II) oxalate decomposes into MnO: Together with manganese sulfate, MnO is a component of fertilizers and food additives. Many thousands of tons are consumed annually for this purpose. Other uses include: a catalyst in the manufacture of allyl alcohol, ceramics, paints, colored glass, bleaching tallow and textile printing. Manganese(II) oxide Manganese(II) oxide is an inorganic compound with chemical formula MnO. It forms green crystals. The compound is produced on a large scale
