Abstract: 3'-Phosphoadenosine 5'-phosphosulfate transporters (PAPSTs) play an important role in transporting 3'-phosphoadenosine 5'-phosphosulfate (PAPS), the universal sulfuryl donor for sulfation, from the cytosol into the lumen of the Golgi apparatus. Here, we describe three methods for… read more here.

Abstract: The synthesis of sulfated polysaccharides involves the sulfation of simpler polysaccharide substrates, through the action sulfotransferases using the cofactor, 3′-phosphoadenosine-5′-phosphosulfate (PAPS). Three enzymes are essential for the in vitro synthesis of PAPS, namely, pyrophosphatase (PPA),… read more here.

Abstract: 3'-Phosphoadenosine 5'-phosphosulfate (PAPS) is the essential sulfate donor for sulfation modifications in crucial biomolecules. Human bifunctional 3'-phosphoadenosine-5'-phosphosulfate synthase 1 (hPAPSS1) directly synthesizes PAPS in two sequential steps, circumventing the inefficiencies of multienzyme systems. However, unsatisfactory… read more here.

Abstract: Sulfotransferases (STs) are ubiquitous enzymes that participate in a vast number of biological processes involving sulfuryl group (SO3) transfer. 3′-phosphoadenosine 5′-phosphosulfate (PAPS) is the universal ST cofactor, serving as the “active sulfate” source in cells.… read more here.
