4-Methylaminobutanoate oxidase (formaldehyde-forming)

4-methylaminobutanoate oxidase (formaldehyde-forming) (EC 1.5.3.19, mabO (gene)) is an enzyme with systematic name 4-methylaminobutanoate:oxygen oxidoreductase (formaldehyde-forming). This enzyme catalyses the following chemical reaction

4-methylaminobutanoate + O₂ + H₂O

\rightleftharpoons

4-aminobutanoate + formaldehyde + H₂O₂

This enzyme is a flavoprotein (FAD).
