Arginine 2-monooxygenase

In enzymology, an arginine 2-monooxygenase (EC number|1.13.12.1) is an enzyme that catalyzes the chemical reaction

:L-arginine + O₂ $ightleftharpoons$ 4-guanidinobutanamide + CO₂ + H₂O

Thus, the two substrates of this enzyme are L-arginine and O₂, whereas its 3 products are 4-guanidinobutanamide, CO₂, and H₂O.

This enzyme belongs to the family of oxidoreductases, specifically those acting on single donors with O₂ as oxidant and incorporation of two atoms of oxygen into the substrate (oxygenases). The oxygen incorporated need not be derived from O with incorporation of one atom of oxygen (internal monooxygenases o internal mixed-function oxidases). The systematic name of this enzyme class is L-arginine:oxygen 2-oxidoreductase (decarboxylating). Other names in common use include arginine monooxygenase, arginine decarboxylase, arginine oxygenase (decarboxylating), and arginine decarboxy-oxidase. This enzyme participates in urea cycle and metabolism of amino groups. It has one cofactor: the flavin FAD.
