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.

Possible lysine decarboxylase. The members of this family share a highly conserved motif PGGXGTXXE that is probably functionally important. This family includes proteins annotated as lysine decarboxylases, although the evidence for this is not clear.

TIGR00730 family protein. This model represents one branch of a subfamily of proteins of unknown function. Both PSI-BLAST and weak hits by This model show a low level of similarity to and suggest an evolutionary relationship of the subfamily to the DprA/Smf family of DNA-processing proteins involved in chromosomal transformation with foreign DNA. Both Aquifex aeolicus and Mycobacterium leprae have one member in each of two branches of this subfamily, suggesting that the branches may have distinct functions [Hypothetical proteins, Conserved].

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.
