4-Methylaminobutanoate oxidase (methylamine-forming)

4-methylaminobutanoate oxidase (methylamine-forming) (, mao (gene)) is an enzyme with systematic name 4-methylaminobutanoate methylamidohydrolase. This enzyme catalyses the following chemical reaction


 * 4-methylaminobutanoate + O2 + H2O $$\rightleftharpoons$$ succinate semialdehyde + methylamine + H2O2

The enzyme participates in the nicotine degradation in soil bacterium Arthrobacter nicotinovorans.
