Monoamine oxidase A, also known as MAO-A, is an enzyme (E.C. 1.4.3.4) that in humans is encoded by the MAOA gene. [ 5 ] [ 6 ] This gene is one of two neighboring gene family members that encode mitochondrial enzymes which catalyze the oxidative deamination of amines , such as dopamine , norepinephrine , and serotonin .
Monoamine oxidase inhibitors (MAOIs) are a class of drugs that inhibit the activity of one or both monoamine oxidase enzymes: monoamine oxidase A (MAO-A) and monoamine oxidase B (MAO-B). They are best known as effective antidepressants , especially for treatment-resistant depression and atypical depression . [ 1 ]
Monoamine oxidases (MAO) (EC 1.4.3.4) are a family of enzymes that catalyze the oxidation of monoamines, employing oxygen to clip off their amine group. [ 1 ] [ 2 ] They are found bound to the outer membrane of mitochondria in most cell types of the body.
2-NAP is a potent monoamine oxidase inhibitor (MAOI), specifically of monoamine oxidase A (MAO-A) (IC 50 Tooltip half-maximal effective concentration = 420 nM). [8] [3] 1-NAP is an MAOI as well, also of MAO-A (IC 50 = 5,630 nM), but was about 13-fold less potent than 2-NAP. [3] Neither 2-NAP or 1-NAP inhibited monoamine oxidase B (MAO-B) (IC 50 ...
In vertebrates, MAO plays an important role in regulating the intracellular levels of amines via their oxidation; these include various neurotransmitters, neurotoxins and trace amines. [3] In lower eukaryotes such as aspergillus and in bacteria the main role of amine oxidases is to provide a source of ammonium. [ 4 ]
Tranylcypromine, sold under the brand name Parnate among others, [1] is a monoamine oxidase inhibitor (MAOI). [4] [7] More specifically, tranylcypromine acts as nonselective and irreversible inhibitor of the enzyme monoamine oxidase (MAO).

Brunner syndrome is caused by a monoamine oxidase A (MAOA) deficiency, which leads to an excess of monoamines in the brain, such as serotonin, dopamine, and norepinephrine (noradrenaline). In both mice and humans, a mutation was located on the eighth exon of the MAO-A gene, which created a dysfunctional MAO-A gene.
