CC -!- FUNCTION: Catalyzes the oxidative deamination of primary and some
CC secondary amine such as neurotransmitters, with concomitant reduction
CC of oxygen to hydrogen peroxide and has important functions in the
CC metabolism of neuroactive and vasoactive amines in the central nervous
CC system and peripheral tissues. Preferentially oxidizes serotonin. Also
CC catalyzes the oxidative deamination of kynuramine to 3-(2-aminophenyl)-
CC 3-oxopropanal that can spontaneously condense to 4-hydroxyquinoline.
CC {ECO:0000250|UniProtKB:P21396}.
