Common Namecob(II)inamide
Descriptioncob(II)inamide is a cobalt-containing metabolite classified as a member of the cobalamin (vitamin B12) chemical class. Its chemical structure features a cobalt ion coordinated to a corrin ring, which is characteristic of cobalamin derivatives. In biochemical pathways, cob(II)inamide serves as a precursor to cob(II)alamin and is involved in various enzymatic reactions. For instance, studies have shown that EutT, an enzyme, interacts with cob(II)inamide during the reduction of Co(II)Cbl, highlighting its role in substrate specificity and mechanism (PMID:30071158 ). Additionally, cob(II)inamide does not promote ligand dissociation in the presence of EutT, indicating its stability as a substrate analogue (PMID:25914129 ). Furthermore, it has been observed that cob(II)inamide can form derivatives through interactions with coenzyme analogs, which lack the nucleotide moiety, leading to the cleavage of the cobalt-carbon bond (PMID:9537996 ). Its reactivity has been explored in the context of radical chemistry, where it participates in alkylation reactions and exhibits diastereomeric preferences (PMID:11669778 ). Overall, cob(II)inamide plays a significant role in the chemistry of cobalamin derivatives and their associated biological pathways.
