MMAA [ENSP00000497008]
Methylmalonic aciduria type A protein, mitochondrial; GTPase, binds and hydrolyzes GTP (PubMed:28497574, PubMed:20876572). Involved in intracellular vitamin B12 metabolism, mediates the transport of cobalamin (Cbl) into mitochondria for the final steps of adenosylcobalamin (AdoCbl) synthesis. Functions as a G- protein chaperone that assists AdoCbl cofactor delivery from MMAB to the methylmalonyl-CoA mutase (MMUT) and reactivation of the enzyme during catalysis .
