L-amino-acid oxidase BjussuLAAO-I

UniProtKB accession:  Q6TGQ9

Grouped By:  Matching UniProtKB accession

UniProtKB description:  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 (PubMed:22490662). Shows high specificity for L-Met, L-Leu, L-Phe, L-Tyr, L-Ile, L-Trp, a moderate activity on L-Cys and low activity on L-Val, L-Lys, L-Arg, L-His, L-Gln, L-Thr and L-Ser (PubMed:22490662). Exhibits diverse biological activities, such as hemorrhage, hemolysis, edema, apoptosis of vascular endothelial cells or tumor cell lines, and antibacterial, as well as regulation of platelet aggregation (By similarity). Effects of snake L-amino oxidases on platelets are controversial, since they either induce aggregation or inhibit agonist-induced aggregation (By similarity). These different effects are probably due to different experimental conditions (By similarity). In vitro, shows parasiticidal activities against both trypanosomes and leishmania, as a result of enzyme-catalyzed hydrogen peroxide production (PubMed:17292326).
