CC -!- FUNCTION: Catalyzes the oxidative deamination of primary and some
CC secondary amines such as neurotransmitters, and exogenous amines
CC including the tertiary amine, neurotoxin 1-methyl-4-phenyl-1,2,3,6-
CC tetrahydropyridine (MPTP), with concomitant reduction of oxygen to
CC hydrogen peroxide and participates in the metabolism of neuroactive and
CC vasoactive amines in the central nervous system and peripheral tissues
CC (PubMed:8003474). Preferentially degrades benzylamine and
CC phenylethylamine (PubMed:8003474). {ECO:0000269|PubMed:8003474}.
