General annotation (Comments)

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. MAOA preferentially oxidizes biogenic amines such as 5-hydroxytryptamine (5-HT), norepinephrine and epinephrine By similarity.

Catalytic activity

RCH2NHR' + H2O + O2 = RCHO + R'NH2 + H2O2.

Cofactor

FAD By similarity.

Subunit structure

Monomer, homo- or heterodimer (containing two subunits of similar size). Each subunit contains a covalently bound flavin. Enzymatically active as monomer By similarity.

Subcellular location

Mitochondrion outer membrane; Single-pass type IV membrane protein; Cytoplasmic side By similarity.

Sequence similarities

Belongs to the flavin monoamine oxidase family.
