FunctionCOAD_STAAW Reversibly transfers an adenylyl group from ATP to 4'-phosphopantetheine, yielding dephospho-CoA (dPCoA) and pyrophosphate (By similarity). Evolutionary Conservation Check, as determined by ConSurfDB. You may read the explanation of the method and the full data available from ConSurf. Publication Abstract from PubMedBacterial phosphopantetheine adenylyltransferase (PPAT) catalyzes the penultimate step in the coenzyme A (CoA) biosynthetic pathway. It catalyzes the reversible transfer of an adenylyl group from ATP to 4'-phosphopantetheine (Ppant) to form dephospho-CoA (dPCoA) and pyrophosphate. Previous structural studies have revealed how several ligands are recognized by bacterial PPATs. ATP, ADP, Ppant and dPCoA bind to the same binding site in a highly similar manner, while CoA binds to a partially overlapping site in a different mode. To provide further structural insights into ligand binding, the crystal structure of Staphylococcus aureus PPAT was solved in a binary complex with 3'-phosphoadenosine 5'-phosphosulfate (PAPS). This study unexpectedly revealed a new mode of ligand binding to PPAT, thus providing potentially useful information for structure-based discovery of inhibitors of bacterial PPATs. The structure of Staphylococcus aureus phosphopantetheine adenylyltransferase in complex with 3'-phosphoadenosine 5'-phosphosulfate reveals a new ligand-binding mode.,Lee HH, Yoon HJ, Kang JY, Park JH, Kim do J, Choi KH, Lee SK, Song J, Kim HJ, Suh SW Acta Crystallogr Sect F Struct Biol Cryst Commun. 2009 Oct 1;65(Pt 10):987-91., Epub 2009 Sep 23.
