Metabolite Identification
Common NameCobalt-precorrin 8
DescriptionCobalt-precorrin 8 is a cobalt-containing metabolite that belongs to the chemical class of precorrins, which are intermediates in the biosynthesis of cobalamin (vitamin B12). Its chemical structure features a corrin ring with a cobalt ion coordinated at the center, which is essential for its biological function. Cobalt-precorrin 8 is produced during the anaerobic pathway of cobalamin synthesis, where it serves as an important intermediate formed through the action of the CbiT enzyme. This enzyme exhibits dual functionality, acting as both a cobalt-precorrin-7 C15-methyltransferase and a C12-decarboxylase, facilitating the conversion of cobalt-precorrin-7 to cobalt-precorrin 8 (PMID:23688113 ). This step is crucial in the overall pathway leading to the production of vitamin B12, which is vital for various biological processes, including DNA synthesis and red blood cell formation. The intricate chemistry of cobalt-precorrin 8 highlights its role in the complex biosynthetic pathways that underpin essential nutrient production in microorganisms.
