Manganese Peroxidase is a hemoprotein involved in the oxidative degradation of lignin in white rot basidiomycetes. It catalyzes the oxidation of Mn(II) to Mn(III) by H2O2. The highly reactive Mn(III) is stabilized via chelation in the presence of dicarboxylic acid:

2 Mn(II) + 2 H+ + H2O2 → 2 Mn(III) + 2 H2O

Reaction conditions:
Optimal reaction at pH 4.5, Temperature range 15 - 60 °C
