Either of two enzymes, found in the outer membrane of mitochondria, that degrade biogenic amines and are thus responsible for the destruction of transmitter substances at neuronal synapses
-the enzyme that breaks down dopamine, norepinephrine, and Epinephrine in synapses Two types are present, types A and B Certain drugs can inhibit the action of MAOs; these drugs are called MAO inhibitors
Monoamine oxidase (MAO) is an enzyme that catalyzes the oxidation of a large variety of monoamines, including epinephrine, norepinephrine, and serotonin; it is found in most tissues, particularly the liver and nervous system Drugs that act as inhibitors of this enzyme are widely used in the treatment of depression
