adenine 3',5'-bis-phosphate Adenine () (nucleoside#List of nucleosides and corresponding nucleobases, symbol A or Ade) is a nucleobase (a purine derivative). It is one of the four nucleobases in the nucleic acid of DNA that are represented by the letters G–C–A–T. The ...

and heparan sulfate- glucosamine 3-sulfate. This enzyme belongs to the family of transferences, specifically the transformer, which transfer sulfur-containing groups. The systematic name of this enzyme class is 3'-phosphorylation-sulfate: eparin sulfateglucose 3-nontransferable. Other names in common use include glucose 3-O-nontransferable, heparin sulfate D-glucose 3-O-nontransferable, and formalism/isomerism 2 (3-OAT-2, HST). This enzyme participates in heparan sulfate biosynthesis and
