L-amino-acid oxidase

Gene

Organism
Bitis gabonica (Gaboon adder) (Gaboon viper)
Status
Reviewed-Annotation score: Annotation score: 3 out of 5-Experimental evidence at transcript 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 of vascular endothelial cells or tumor cell lines, 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.

Similar proteinsi

Links to similar proteins from the UniProt Reference Clusters (UniRef) at 100%, 90% and 50% sequence identity:
100%UniRef100 combines identical sequences and sub-fragments with 11 or more residues from any organism into Uniref entry.
90%UniRef90 is built by clustering UniRef100 sequences that have at least 90% sequence identity to, and 80% overlap with, the longest sequence (a.k.a seed sequence).
50%UniRef50 is built by clustering UniRef90 seed sequences that have at least 50% sequence identity to, and 80% overlap with, the longest sequence in the cluster.
