Common NameAdenosylcobalamin 5'-phosphate
DescriptionAdenosylcobalamin 5'-phosphate is an intermediate in the synthesis of vitamin B12. Until recently it was believed that the last reaction in the biosynthesis of coenzyme B12 was the linking of alpha-ribazole (a product of 5,6-dimethylbenzimidazole ) to adenosylcobinamide-GDP, in a reaction catalyzed by cobalamin synthase. However, it was recently shown that the true substrate for the enzyme is alpha-ribazole-5'-P, and not alpha-ribazole, and that the product of the reaction is actually adenosylcobalamin 5'-phosphate. The dephosphorylation of adenosylcobalamin 5'-phosphate by the CobC protein leads to coenzyme B12.
