IUBMB Enzyme Nomenclature


Accepted name: L-arginine oxidase

Reaction: L-arginine + H2O + O2 = 5-guanidino-2-oxopentanoate + NH3 + H2O2

Systematic name: L-arginine:oxygen oxidoreductase (deaminating)

Comments: Contains FAD. The enzyme from cyanobacteria can also act on other basic amino acids with lower activity. The enzyme from the bacterium Pseudomonas sp. TPU 7192 is highly specific.
