L-ascorbate oxidase

oxidoreductase

L-ascorbate oxidase, plant type. Members of this protein family are the copper-containing enzyme L-ascorbate oxidase (EC 1.10.3.3), also called ascorbase. This family is found in flowering plants, and shows greater sequence similarity to a family of laccases (EC 1.10.3.2) from plants than to other known ascorbate oxidases.

Multicopper oxidase. This entry contains many divergent copper oxidase-like domains that are not recognised by the pfam00394 model.

laccase, plant. Members of this protein family include the copper-containing enzyme laccase (EC 1.10.3.2), often several from a single plant species, and additional, uncharacterized, closely related plant proteins termed laccase-like multicopper oxidases. This protein family shows considerable sequence similarity to the L-ascorbate oxidase (EC 1.10.3.3) family. Laccases are enzymes of rather broad specificity, and classification of all proteins scoring about the trusted cutoff of this model as laccases may be appropriate.
