Adenosine 3′-phosphate 5′-phosphosulfate or 3′-Phosphoadenosine-5′-phosphosulfate (PAPS) is produced by the action of PAPS synthase in the cytoplasm and nucleus in animal cells. It is also found in the cytoplasm and plastids of plant cells.
Application
Adenosine 3′-phosphate 5′-phosphosulfate triethylammonium salt has been used in the determination of human 3-O-sulfotransferase-1 (3-OST-1) and aryl-sulfotransferase (AST-IV) enzyme activity.
Actions biochimiques/physiologiques
3′-Phosphoadenosine-5′-phosphosulfate (PAPS) acts as a sulfate donor and serves as a substrate for sulfotransferases (STs).

Heparosan, with a linear chain of disaccharide repeating units of → 4) β-D-glucuronic acid (GlcA) (1 → 4)-α-D-N-acetylglucosamine (GlcNAc) (1→, is a potential starting chemical for heparin synthesis. However, the chemoenzymatic synthesis of single-site sulfated heparosan and its antitumor activity have not been studied.
