General annotation (Comments)

Function

Catalyzes an oxidative deamination of predominantly hydrophobic and aromatic L-amino acids (L-Met, followed by L-Leu, L-Phe, L-Trp, L-Tyr, L-Ile), thus producing hydrogen peroxide that may contribute to the diverse toxic effects of this enzyme. Exhibits diverse biological activities, such as apoptosis, cytotoxicity towards several cancer cell lines, induction of platelet aggregation, induction of moderate mouse paw edema, and antibacterial activities against both Gram-positive and Gram-negative bacteria. Unlike other snake venom L-amino acid oxidases, does not induce hemorrhage (with 50 µg of enzyme). May also act in hemolysis, and antiparasitic activities. 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. Ref.1 Ref.2

Catalytic activity

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

Cofactor

FAD By similarity.

Subunit structure

Homodimer; non-covalently linked By similarity.

Subcellular location

Secreted Ref.1.

Tissue specificity

Expressed by the venom gland. Ref.1

Post-translational modification

Contains 2 disulfide bonds By similarity.

N-glycosylated Probable. Ref.1

Miscellaneous

Has parasiticidal activities against both trypanosomes and leishmania, as a result of enzyme-catalyzed hydrogen peroxide production (Ref.2).

Sequence similarities

Belongs to the flavin monoamine oxidase family. FIG1 subfamily.
