CHEMICAL1 and enzymic2 studies from these two laboratories suggested that coenzyme A is best represented by formula (I) (cf. ref. 3). While the synthesis of various fragments of the molecule4 has lent considerable support to this structure, the enzymic and chemical evidence did not agree on one point.

Coenzyme A: to make it or uptake it?
Nature Reviews Molecular Cell Biology, 2016The consensus has been that intracellular coenzyme A (CoA) is obtained exclusively by de novo biosynthesis via a universal, conserved five-step pathway in the cell cytosol. However, old and new evidence suggest that cells (and some microorganisms) have several strategies to obtain CoA, with 4'-phosphopantetheine (P-PantSH; the fourth intermediate in ...

Coenzymes I: Organic Coenzymes
2007Most enzymatic reactions proceed with chemical changes that cannot be brought about by the side chains of amino acid residues. These enzymes function in cooperation with coenzymes and cofactors, which lend physicochemical potentialities not found in amino acids.

Abstract An improved procedure for the chemical synthesis of coenzyme A by anhydride-anion exchange is described. A mixture of the 2′,5′- and 3′,5′-diphosphastes of adenosine is treated with diphenylphosphorochloridate to give P 1 -adenosine (2′3′-cyclic phosphate)-5′- P 2 -diphenylpyrophosphate quantitatively. This is then treated with pantethine

Coenzymes are small organic molecules that supply a varied set of reactive groups to protein enzymes, thereby diversifying catalysis beyond the chemistries of amino acid sidechains. As RNA structures begin with a more limited chemical diversity than proteins, it seems likely that RNA enzymes would also use functional groups from other molecules to ...
