Applicazioni

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.

Azioni biochim/fisiol

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 coenzyme A (CoA) biosynthesis: the reversible adenylation of 4'-phosphopantetheine yielding 3'-dephospho-CoA and pyrophosphate. Wild-type PPAT from Escherichia coli was purified to homogeneity. N-terminal sequence analysis revealed that the enzyme is encoded by
