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 exporter manganese efflux pump. Manganese sensitivity and intracellular manganese levels significantly increased in bacteria when the "mntP" (formerly "yebN") gene, which encodes the MntP efflux pump, was deleted. While manganese is a highly important trace nutrient for organisms from bacteria to humans, acting as an important element in the defense against oxidative stress and as an enzyme cofactor, it becomes toxic when present in excess. Manganese exporter The Manganese (Mn2+) Exporter (MntP) Family (TC# 2.A.107) is a member of the Lysine Exporter (LysE) Superfamily. The MntP family is a small family whose members have been found in bacteria and archaea. MntP
