<unk> s <unk>  () are a family of enzymes that catalyze the oxidation of<unk> s, employing oxygen to clip off their amine group. They are found bound to the outer membrane of mitochondria in most cell types of the body. The first such enzyme was discovered in 1928 by Mary Bernheim in the liver and was named tyramine<unk> . The<unk> s belong to the protein family of flavin-containing amine oxidoreductases.<unk> s are important in the breakdown of<unk> s ingested in food, and also serve to inactivate<unk>  neurotransmitters. Because of the latter, they are involved in a number of psychiatric and neurological diseases, some of which can be treated with<unk>  inhibitors <unk> Is) which block the action of<unk> s.
