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. 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 … See more In humans there are two types of MAO: MAO-A and MAO-B. • Both are found in neurons and astroglia. • Outside the central nervous system: MAO-A appears at … See more They are well known enzymes in pharmacology, since they are the target for the action of a number of monoamine oxidase inhibitor drugs. MAO-A is particularly important in the catabolism of monoamines ingested in food. Both MAOs are also vital to the … See more The genes encoding MAO-A and MAO-B are located side-by-side on the short arm of the X chromosome, and have about 70% sequence … See more • Cheese effect • I2 receptor • Monoamine oxidase inhibitor See more Monoamine oxidases catalyze the oxidative deamination of monoamines. Oxygen is used to remove an amine group (plus the adjacent … See more Because of the vital role that MAOs play in the inactivation of neurotransmitters, MAO dysfunction (too much or too little MAO activity) is thought … See more Unlike many other enzymes, MAO-B activity is increased during aging in the brain of humans and other mammals.
