General annotation (Comments)

Function

Catalyzes an oxidative deamination of predominantly hydrophobic and aromatic L-amino acids. Has an ability to induce hemorrhage and has an antibacterial activity By similarity. Has an ability to induce apoptosis. Inhibits both agonist- and shear stress-induced platelet aggregation (SIPA) dose-dependently.

Catalytic activity

An L-amino acid + H2O + O2 = a 2-oxo acid + NH3 + H2O2.

Cofactor

FAD. Ref.3

Subunit structure

Homodimer. Ref.2

Subcellular location

Secreted.

Tissue specificity

Expressed by the venom gland.

Sequence similarities

Belongs to the flavin monoamine oxidase family. FIG1 subfamily.
