Metabolite Identification
Common NameS-Adenosylmethioninamine
DescriptionS-Adenosylmethioninamine, also known as decarboxy-adomet or dadomet, belongs to the class of organic compounds known as 5'-deoxy-5'-thionucleosides. These are 5'-deoxyribonucleosides in which the ribose is thio-substituted at the 5'position by a S-alkyl group. S-Adenosylmethioninamine is a very strong basic compound (based on its pKa). S-Adenosylmethioninamine exists in all living species, ranging from bacteria to humans. Within humans, S-adenosylmethioninamine participates in a number of enzymatic reactions. In particular, S-adenosylmethioninamine can be biosynthesized from S-adenosylmethionine; which is mediated by the enzyme S-adenosylmethionine decarboxylase proenzyme. In addition, S-adenosylmethioninamine and putrescine can be converted into 5'-methylthioadenosine and spermidine through its interaction with the enzyme spermidine synthase. In humans, S-adenosylmethioninamine is involved in the metabolic disorder called homocystinuria-megaloblastic anemia due to defect in cobalamin metabolism, cblg complementation type. The S-adenosyl derivative of methioninamine.
