What is monoamine oxidase?

  • (noun): An enzyme that catalyzes the oxidation of many body compounds (e.g., epinephrine and norepinephrine and serotonin).
    Synonyms: MAO

Monoamine Oxidase

L-Monoamine oxidases (MAO) (EC are a family of enzymes that catalyze the oxidation of monoamines. They are found bound to the outer membrane of mitochondria in most cell types in the body. The enzyme was originally discovered by Mary Bernheim in the liver and was named tyramine oxidase. They belong to the protein family of flavin-containing amine oxidoreductases.
