DE   manganese peroxidase.
AN   Mn-dependent peroxidase.
CA   2 H(+) + H2O2 + 2 Mn(2+) = 2 H2O + 2 Mn(3+).
CC   -!- The enzyme from white rot basidiomycetes is involved in the oxidative
CC       degradation of lignin.
CC   -!- The enzyme oxidizes a bound Mn(2+) ion to Mn(3+) in the presence of
CC       hydrogen peroxide.
CC   -!- The product, Mn(3+), is released from the active site in the presence
CC       of a chelator (mostly oxalate and malate) that stabilizes it against
CC       disproportionation to Mn(2+) and insoluble Mn(4+).
CC   -!- The complexed Mn(3+) ion can diffuse into the lignified cell wall,
CC       where it oxidizes phenolic components of lignin and other organic
CC       substrates.
CC   -!- It is inactive with veratryl alcohol or nonphenolic substrates.
