RT lignin and manganese peroxidase isozymes and in the degradation of lignin
RT by Phlebia radiata.";

CC -!- FUNCTION: Catalyzes the oxidation of Mn(2+) to Mn(3+). The latter,
CC acting as a diffusible redox mediator, is capable of oxidizing a
CC variety of lignin compounds. {ECO:0000269|Ref.2}.
CC -!- CATALYTIC ACTIVITY:
CC Reaction=2 H(+) + H2O2 + 2 Mn(2+) = 2 H2O + 2 Mn(3+);
CC Xref=Rhea:RHEA:22776, ChEBI:CHEBI:15377, ChEBI:CHEBI:15378,
CC ChEBI:CHEBI:16240, ChEBI:CHEBI:29035, ChEBI:CHEBI:29041;
CC EC=1.11.1.13;
CC -!- COFACTOR:
CC Name=heme b; Xref=ChEBI:CHEBI:60344;
CC Evidence={ECO:0000255|PROSITE-ProRule:PRU00297};
CC Note=Binds 1 heme b (iron(II)-protoporphyrin IX) group per subunit.
CC {ECO:0000255|PROSITE-ProRule:PRU00297};
CC -!- COFACTOR:
CC Name=Ca(2+); Xref=ChEBI:CHEBI:29108;
CC Evidence={ECO:0000255|PROSITE-ProRule:PRU00297};
CC Note=Binds 2 calcium ions per subunit. {ECO:0000255|PROSITE-
CC ProRule:PRU00297};
CC -!- SUBCELLULAR LOCATION: Secreted.
CC -!- INDUCTION: By a combination of high manganese and malonate levels.
CC {ECO:0000269|Ref.2}.
CC -!- SIMILARITY: Belongs to the peroxidase family. Ligninase subfamily.
CC {ECO:0000305}.
