show Brenda entry

EC number

1.4.3.25

Accepted name

L-arginine oxidase

Reaction

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

Systematic name

L-arginine:oxygen oxidoreductase (deaminating)

Comment

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.
