Application

Dephosphocoenzyme A is the direct precursor of coenzyme A. It is used for the synthesis of coenzyme A by bifunctional CoA Synthase (CoASy, 4′-phosphopantetheine adenylyltransferase/dephospho-CoA kinase) which performs the transfer of the γ-phosphate of ATP to dephosphocoenzyme A.

3′-Dephosphocoenzyme A has been used as a substrate to initiate transcription.

Biochem/physiol Actions

3′-Dephosphocoenzyme A (DepCoA), also called desphosphoCoA (dpCoA), is synthesized from 4-phosphopantetheine by the enzyme phosphopanthetheine adenylyltransferase. It is an intermediate in coenzyme A biosynthetic pathway. In the presence of dephospho-CoA kinase (CoaE), dephosphocoenzyme A is converted to coenzyme A. 3′-Dephosphocoenzyme shares adenosine-diphosphate substructure as like the purines and is a non-canonical nucleotide and is an initiator of transcription initiation. It is routinely used in in vitro transcription studies to initiate RNA synthesis.
