Methylmalonic aciduria and homocystinuria type D protein, mitochondrial (MMADHC)

Involved in cobalamin metabolism (PubMed:18385497, PubMed:23415655, PubMed:24722857, PubMed:26364851). Plays a role in regulating the biosynthesis of two coenzymes, methylcobalamin and adenosylcobalamin (PubMed:18385497, PubMed:24722857).

Plays a role in regulating the ratio of methylcobalamin and adenosylcobalamin (PubMed:23415655, PubMed:24722857). Promotes oxidation of cob(II)alamin jumped to MMACHC (PubMed:26364851).
