A cobalamin (cbl) derivative in which the substituent is deoxyadenosyl. It is one of two metabolically active forms synthesized upon ingestion of vitamin B12 and is the predominant form in the liver; it acts as a coenzyme in the reaction catalyzed by methylmalonyl-CoA mutase (MCM; E.C. 5.4.99.2). Inborn errors of vitamin B12 metabolism are autosomal recessive disorders and have been classified into nine distinct complementation classes. Disorders affecting adenosylcobalamin cause methylmalonic acidemia and metabolic acidosis. Methylmalonyl-CoA mutase catalyzes the conversion of L-methylmalonyl-CoA to succinyl-CoA and uses adenosylcobalamin (AdoCbl) as a cofactor. Cbl must be transported into mitochondria, reduced and adenosylated before it can be utilized by MCM. (A405)."}]
