Gene Gene information from NCBI Gene database.
Entrez ID 4594
Gene name Methylmalonyl-CoA mutase
Gene symbol MMUT
Synonyms (NCBI Gene)
MCMMUT
Chromosome 6
Chromosome location 6p12.3
Summary 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 ma
