Congenital methylmalonic acidemia: a variant of the B12 'non-responsive' form with evidence for reduced affinity of methylmalonyl-CoA mutase for its B12-coenzyme.

Methylmalonate metabolism was investigated in fibroblasts and leukocytes of two unrelated patient with a B12-nonresponsive type of congenital methylmalonic acidemia. Intact fibroblasts from both patients showed a defective metabolism of methyl-14 c-malonate to 14CO2, whereas no such defect was found in their intact peripheral leukocytes. In disrupted fibroblasts, the conversion of methylmalonyl coenzyme A to succinyl coenzyme A was markedly reduced but was completely normalized by the addition of 5'-deoxyadenosylcobalamin (AdoCb1; 10(-5) mol/l), the specific coenzyme of methylmalonyl coenzyme A mutase. Assays with decreasing concentrations of AdoCbl (10(-5)-10(-11) mol/l) suggested a reduced affinity of the mutase apoenzyme for its coenzyme, implicating yet another variant of this heterogeneous disease.[1]
