Monoamine Oxidase

Definition of Monoamine Oxidase:

An enzyme catalyzing the removal of an amine group from a variety of substrates, including norepinephrine and dopamine.  MAO inhibitors block the action of MAO, thus raising the levels of the monoamine neurotransmitters such as norepinephrine, epinephrine, dopamine, and serotonin – which have significant effects on mood and behavior.  Epinephrine, norepinephrine and serotonin are normally deactivated by MAO-A while dopamine and phenylethylamine are normally metabolized by MAO-B.
