Dephospho-CoA kinase () is an enzyme that catalyzes the final chemical reaction in the biosynthesis of coenzyme A:
The reaction transfers a phosphate group from the cofactor, adenosine triphosphate (ATP), which is converted to adenosine diphosphate (ADP).
This enzyme is a transferases, specifically one transferring phosphorus-containing groups (phosphotransferases) with an alcohol group as acceptor. The systematic name of this enzyme class is ATP:dephospho-CoA 3'-phosphotransferase. Other names in common use include dephosphocoenzyme A kinase (phosphorylating), 3'-dephospho-CoA kinase, and dephosphocoenzyme A kinase.
Structural studies As of late 2007, 8 structures have been solved for this class of enzymes, with PDB accession codes , , , , , , , and .
