WebJul 21, 1998 · In higher organisms PAPS synthesis is catalyzed by a bifunctional sulfurylase kinase (SK) polypeptide having both ATP-sulfurylase and adenosine-phosphosulfate kinase activities. We report the identification of a gene family encoding murine SK proteins with these two activities. WebSep 17, 2024 · PAPS was synthesized from ATP and inorganic sulfate in a one-pot reaction catalyzed by ATP sulfurylase, pyrophosphatase, and APS kinase. ATP sulfurylase catalyzed the combination of disodium sulfate and ATP to form APS. Pyrophosphatase hydrolyzed pyrophosphate to drive the reaction forward. WebMar 11, 2013 · However, because we are able to rescue the defects of Bpnt1 null mice by repressing PAPS synthesis, and thereby depleting the substrate of SULTs, it is unlikely that impaired sulfation is responsible for the liver failure.
