Monoamine oxidase B, encoded by the MAOB gene, is an enzyme on the outer mitochondrial membrane that mainly metabolizes dopamine.
Monoamine oxidase B, also known as MAOB, is an enzyme that in humans is encoded by the MAOB gene. It is an enzyme located in the outer mitochondrial membrane. In contrast, monoamine oxidase B (MAOB) mainly metabolizes dopamine (DA) (and other less clinically relevant chemicals).
