Protein

L-amino-acid oxidase

Gene
N/A
Organism
Crotalus adamanteus (Eastern diamondback rattlesnake)
Status
Reviewed - Annotation score: 4 out of 5- Experimental evidence at protein leveli

Functioni

Catalyzes an oxidative deamination of predominantly hydrophobic and aromatic L-amino acids (L-Leu), thus producing hydrogen peroxide that may contribute to the diverse toxic effects of this enzyme. Exhibits diverse biological activities, such as hemolysis, edema, hemorrhage, apoptosis, antibacterial and antiparasitic activities, as well as regulation of 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 similarity).By similarity

Catalytic activityi

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