In enzymology, a pantetheine-phosphate adenylyltransferase (EC 2.7.7.3) is an enzyme that catalyzes the chemical reaction
ATP + 4'-PhosphopantetheineThus, the two substrates of this enzyme are ATP and 4'-Phosphopantetheine, whereas its two products are diphosphate and 3'-dephospho-CoA.
This enzyme belongs to the family of transferases, specifically those transferring phosphorus-containing nucleotide groups (nucleotidyltransferases). The systematic name of this enzyme class is ATP:pantetheine-4'-phosphate adenylyltransferase. Other names in common use include dephospho-CoA pyrophosphorylase, pantetheine phosphate adenylyltransferase, dephospho-coenzyme A pyrophosphorylase, and 3'-dephospho-CoA pyrophosphorylase. This enzyme participates in pantothenate and coa biosynthesis.
