Comments

FUNCTION: Catalyzes an oxidative deamination of predominantly hydrophobic and aromatic L-amino acids (the most specific substrate is L-Phe, followed by L-Met, L-Leu, L-Phe, L-Ile, L-Arg and L-His). Inhibits both ADP-induced platelet aggregation dose-dependently. Has an ability to induce apoptosis in cultured HeLa and K562 cells. May have an ability to induce hemorrhage. May have an antibacterial activity.
CATALYTIC ACTIVITY: An L-amino acid + H₂O + O₂ = a 2-oxo acid + NH₃ + H₂O₂.
COFACTOR: FAD (By similarity).
SUBUNIT: Homodimer.
SUBCELLULAR LOCATION: Secreted.
TISSUE SPECIFICITY: Expressed by the venom gland.
PTM: Glycosylated (By similarity).
SIMILARITY: Belongs to the flavin monoamine oxidase family. FIG1 subfamily.
