Subcellular location

Subcellular Location:
Mitochondrion outer membrane; Single-pass type IV membrane protein; Cytoplasmic side.

Function

Function:
Catalyzes the oxidative deamination of biogenic and xenobiotic amines and has important functions in the metabolism of neuroactive and vasoactive amines in the central nervous system and peripheral tissues. MAOB preferentially degrades benzylamine and phenylethylamine.
Catalytic Activity:
RCH(2)NHR' + H(2)O + O(2) = RCHO + R'NH(2) + H(2)O(2).
