General annotation (Comments)
Catalyzes an oxidative deamination of predominantly hydrophobic and aromatic L-amino acids, thus producing hydrogen peroxide that may contribute to the diverse toxic effects of this enzyme. Exhibits diverse biological activities, such as hemolysis, edema, apoptosis, as well as induction of platelet aggregation. Effects of snake L-amino oxidases on platelets are controversial, since they either induce aggregation or inhibit agonist-induced aggregation. These different effects are probably due to different experimental conditions. Unlike other snake venom L-amino acid oxidases, does not induce hemorrhage. This protein may also have antibacterial and antiparasitic activities. Ref.1
An L-amino acid + H2O + O2 = a 2-oxo acid + NH3 + H2O2.
FAD By similarity.
Homodimer; non-covalently linked. Ref.1
Expressed by the venom gland.
Contains 2 disulfide bonds By similarity.
N-glycosylated By similarity.
