Methylmalonyl Coenzyme A mutase Recombinant Rabbit Monoclonal Antibody [JE62-36]

Methylmalonyl-CoA mutase (MCM), mitochondrial, also known as methylmalonyl-CoA isomerase, is a protein that in humans is encoded by the MUT gene. This vitamin B12-dependent enzyme catalyzes the isomerization of methylmalonyl-CoA to succinyl-CoA in humans. Mutations in MUT gene may lead to various types of methylmalonic aciduria. A deficiency of this enzyme is responsible for an inherited disorder of metabolism, methylmalonyl-CoA mutase deficiency, which is one of the causes of methylmalonic acidemia (also referred to as methylmalonic aciduria or MMA). Either mutations to the gene MUT (encodes methylmalonyl-CoA mutase), or MMAA (encodes a chaperone protein of methylmalonyl-CoA mutase, MMAA protein) can lead to methylmalonyl acidemia. Methylmalonyl-CoA mutase is expressed in high concentrations in the kidney, in intermediate concentrations in the heart, ovaries, brain, muscle, and liver, and in low concentrations in the spleen.
