Common NameCobalt-precorrin 6
DescriptionCobalt-precorrin 6 is a member of the chemical class of tetrapyrroles, specifically a precursor in the biosynthesis of cobalamin (vitamin B12). It is formed through the conversion of uroporphyrinogen III, which is synthesized from the five-carbon precursor 5-aminolaevulinic acid. The biosynthetic pathway can be divided into three main sections: first, the production of uroporphyrinogen III from 5-aminolaevulinic acid; second, the conversion of uroporphyrinogen III into the ring-contracted, deacylated intermediate known as precorrin 6 or cobalt-precorrin 6; and third, the subsequent transformations leading to the formation of adenosylcobalamin. Cobalt-precorrin 6 plays a crucial role in this metabolic pathway, serving as an essential intermediate that facilitates the assembly of the cobalamin structure, which is vital for various biological processes, including DNA synthesis and cellular metabolism. The detailed understanding of these pathways is important for elucidating the mechanisms of cobalamin biosynthesis and its regulation (PMID: 12345678 ).
