  2. Monoamine oxidase A - Wikipedia

    en.wikipedia.org/wiki/Monoamine_oxidase_A

    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 norepinephrine , serotonin and tyramine .

  3. Monoamine oxidase - Wikipedia

    en.wikipedia.org/wiki/Monoamine_oxidase

    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.

  4. Monoamine oxidase inhibitor - Wikipedia

    en.wikipedia.org/wiki/Monoamine_oxidase_inhibitor

    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 ]

  5. Monoamine neurotransmitter - Wikipedia

    en.wikipedia.org/wiki/Monoamine_neurotransmitter

    After release into the synaptic cleft, monoamine neurotransmitter action is ended by reuptake into the presynaptic terminal. There, they can be repackaged into synaptic vesicles or degraded by the enzyme monoamine oxidase (MAO), which is a target of monoamine oxidase inhibitors, a class of antidepressants. [citation needed]

  6. Brunner syndrome - Wikipedia

    en.wikipedia.org/wiki/Brunner_syndrome

    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.

  7. Oxidative deamination - Wikipedia

    en.wikipedia.org/wiki/Oxidative_deamination

    Monoamine oxidases MAO-A and MAO-B play vital roles in the degradation and inactivation of monoamine neurotransmitters such as serotonin and epinephrine. [4] Monoamine oxidases are important drug targets, targeted by MAO inhibitors (MAOIs) such as selegiline. Glutamate dehydrogenase play an important role in oxidative deamination.

  8. 5-Methoxytryptamine - Wikipedia

    en.wikipedia.org/wiki/5-Methoxytryptamine

    5-MT is metabolized by deamination by monoamine oxidase (MAO), specifically monoamine oxidase A (MAO-A) and to a much lesser extent by monoamine oxidase B (MAO-B). [ 12 ] [ 13 ] [ 14 ] [ 36 ] Brain levels of 5-MT following central administration of 5-MT in rats were potentiated by 20-fold by the MAO-A inhibitor clorgyline and by 5.5-fold by the ...

  9. Rasagiline - Wikipedia

    en.wikipedia.org/wiki/Rasagiline

    Rasagiline acts as an inhibitor of the enzyme monoamine oxidase (MAO) and hence is a monoamine oxidase inhibitor (MAOI). [2] More specifically, it is a selective inhibitor of monoamine oxidase B (MAO-B). [2] The drug is thought to work by increasing levels of the monoamine neurotransmitter dopamine in the brain. [2]
