WebMETHYLMALONYL-COA MUTASE Introduction This gene encodes the mitochondrial enzyme methylmalonyl Coenzyme A mutase. In humans, the product of this gene is a vitamin B12-dependent enzyme which catalyzes the isomerization of methylmalonyl-CoA to succinyl-CoA, while in other species this enzyme may have different functions. WebFinally, in a zebrafish model of C9ORF72 -amyotrophic lateral sclerosis, we present evidence that estradiol is neuroprotective. Isoleucine is metabolized via methylmalonyl-CoA mutase encoded by the gene MMUT in a reaction that consumes vitamin B12.

Mutase - Wikipedia

WebMethylmalonyl-CoA mutase (MCM) is one of the special proteins (enzymes) needed to breakdown certain amino acids found in the food we eat. It is needed to breakdown certain fats too. When the amino acids and fats are not broken down normally, substances which are harmful to the body (including methylmalonic acid) build up and can damage the … WebFidelity during cofactor assembly is essential for the proper functioning of metalloenzymes and is ensured by specific chaperones.
