General annotation (Comments)
| Function | Catalyzes an oxidative deamination of predominantly hydrophobic and aromatic L-amino acids. Induces a dose-dependent platelet aggregation. Has an ability to induce apoptosis. Has an antibacterial activity against both Gram-negative and Gram-positive bacteria. Has high antileishmanic activity against the promastigote of Leishmania amazonensis in vitro. May have an ability to induce hemorrhage. Ref.1 |
| Catalytic activity | An L-amino acid + H2O + O2 = a 2-oxo acid + NH3 + H2O2. |
| Cofactor | FAD. |
| Subunit structure | Homodimer. Ref.1 |
| Subcellular location | |
| Tissue specificity | Expressed by the venom gland. |
| Post-translational modification | Glycosylated By similarity. |
| Sequence similarities | Belongs to the flavin monoamine oxidase family. FIG1 subfamily. |
| Biophysicochemical properties | Kinetic parameters: KM=46.7 µM for L-Leu pH dependence: Optimum pH is 6.5. |
