Metabolite Identification
Common NamePrecorrin 4
DescriptionPrecorrin 4 is a cobalt-containing metabolite classified within the chemical class of corrinoids, which are characterized by their complex ring structures and metal coordination. It plays a crucial role in the anaerobic biosynthetic pathway leading to the formation of cobalamin (vitamin B12). The chemical structure of precorrin 4 features a corrin ring that coordinates cobalt at its center, which is essential for its biological activity. In the biosynthetic process, precorrin 4 can be converted into cobalt-precorrin 5A upon the addition of the enzyme CbiF, while the combination of CbiF and CbiG leads to the formation of cobalt-precorrin 5B. These transformations highlight the significance of precorrin 4 as an intermediate in the pathway that synthesizes cobalamin, underscoring its importance in the overall metabolism of organisms that utilize this essential vitamin. The elucidation of these enzymatic roles provides insight into the intricate biochemical pathways involved in corrinoid biosynthesis. (PMID:16866557 )
