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 of manganese in air have dropped. Many racing competitions specifically ban manganese compounds in racing fuel for carts and minibikes. MMT contains 24.4–25.2% manganese. Elevated atmospheric manganese concentrations are strongly correlated with automobile traffic density. The Level of manganese emitted by MMT fuels has been found to be safe for the general population and vulnerable groups such as infants and the elderly by the EPA and European and Canadian environmental agencies. The tobacco plant readily absorbs and accumulates heavy metals such as manganese from the surrounding soil into its leaves. These are subsequently inhaled during tobacco smoking. While manganese is
