In enzymology, a pantetheine-phosphate adenylyltransferase (EC 2.7.7.3) is an enzyme that catalyzes the chemical reaction
Thus, 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.
As of late 2007, 8 structures have been solved for this class of enzymes, with PDB accession codes 1B6T, 1GN8, 1H1T, 1O6B, 1OD6, 1QJC, 1TFU, and 1VLH.
