Protein

L-amino-acid oxidase

Gene
N/A
Organism
Protobothrops mucrosquamatus (Taiwan habu) (Trimeresurus mucrosquamatus)
Status
Reviewed - Annotation score: 3 out of 5- Experimental evidence at protein leveli

Functioni

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. Exhibits diverse biological activities, such as hemorrhage, hemolysis, edema, apoptosis, and antiparasitic activities (By similarity). This protein has antibacterial activity (against E.coli, S.aureus, and B.dysenteriae), cytotoxic activity, as well as an ability to induce 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.By similarity1 Publication

Catalytic activityi

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