General annotation (Comments)

Function	Depolymerization of lignin. Catalyzes the C(alpha)-C(beta) cleavage of the propyl side chains of lignin.
Catalytic activity	1,2-bis(3,4-dimethoxyphenyl)propane-1,3-diol + H2O2 = 3,4-dimethoxybenzaldehyde + 1-(3,4-dimethoxyphenyl)ethane-1,2-diol + H2O.
Cofactor	Binds 2 calcium ions per subunit. Binds 1 heme B (iron-protoporphyrin IX) group per subunit.
Pathway	Secondary metabolite metabolism; lignin degradation.
Developmental stage	Ligninases are expressed during secondary metabolism, and are triggered by nutrient limitation.
Sequence similarities	Belongs to the peroxidase family. Ligninase subfamily.
