Application

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

Actions biochimiques/physiologiques

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.

Phosphopantetheine adenylyltransferase (PPAT) catalyzes the penultimate step in the coenzyme A (CoA) biosynthetic pathway, reversibly transferring an adenylyl group from ATP to 4'-phosphopantetheine (PhP) to form dephosphocoenzyme A. This reaction sits at the branch point between the de novo pathway

Analytical biochemistry, 324(1), 100-105 (2003-12-05)
A rapid and stoichiometric method for the synthesis of analogues of coenzyme A is described. The method links the enzymes pantothenate kinase, phosphopantotheine adenylyltransferase, and dephosphocoenzyme A kinase in vitro to generate a variety of CoA analogues from chemically synthesized
