General annotation (Comments)

Function

A versatile ligninolytic peroxidase that combines the substrate-specificity characteristics of the two other ligninolytic peroxidases, manganese peroxidase and lignin peroxidase. Ref.1

Catalytic activity

Reactive Black 5 + H2O2 = oxidized Reactive Black 5 + 2 H2O.

Donor + H2O2 = oxidized donor + 2 H2O.

Cofactor

Binds 1 heme B (iron-protoporphyrin IX) group per subunit. Ref.2

Binds 2 calcium ions per subunit. Ref.2

Subcellular location

Secreted. Ref.1

Sequence similarities

Belongs to the peroxidase family. Ligninase subfamily.

biophysicochemical properties

Kinetic parameters:

KM=19 µM for manganese

KM=3000 µM for veratryl alcohol

KM=4 µM for reactive black 5

KM=3 µM for 2,2'-azinobis(3-ethylbenzothiazoline-6-sulfonate) (ABTS)
