General annotation (Comments)

Function

Catalyzes the oxidation of Mn2+ to Mn3+. The latter, acting as a diffusible redox mediator, is capable of oxidizing a variety of lignin compounds. Ref.1

Catalytic activity

2 Mn2+ + 2 H+ + H2O2 = 2 Mn3+ + 2 H2O.

Cofactor

Binds 1 heme B (iron-protoporphyrin IX) group per subunit By similarity.

Binds 2 calcium ions per subunit By similarity.

Subcellular location

Secreted. Ref.1

Induction

During wound-healing and by factors which induce suberization. Ref.1

Sequence similarities

Belongs to the peroxidase family. Ligninase subfamily.
