Manganese peroxidase (belonging to the family of oxidoreductases) an enzyme that catalyzes the chemical reaction, releases Mn(III)-carboxylic acid chelate, as peroxidase structures favor Mn(III)-chelates over free Mn(III) ions.
In enzymology, a manganese peroxidase (EC ) is an enzyme that catalyzes the chemical reaction This enzyme belongs to the family of oxidoreductases, to be specific those acting on a peroxide as acceptor (peroxidases). The peroxidase structure favors Mn(III)-chelates over free Mn(III) ions. Mn(III) is unstable in aqueous media, therefore MnP releases it as a Mn(III)-carboxylic acid chelate.
