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. Is highly active on L-Phe, L-Tyr, L-Trp, L-Leu, L-Met, and L-Ile, is moderately active on L-Val, and L-His, and is no or weakly active on L-Ala, L-Arg, L-Pro, L-Thr, L-Ser, L-Glu, L-Gly, and L-Lys. Exhibits diverse biological activities, such as edema, antibacterial (E.coli, and P.aeruginosa) and antiparasitic activities, 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. This protein may also have activities in hemorrhage, hemolysis, and apoptosis.
