Heparan sulfate glucosamine 3-O-sulfotransferase 1

UniProtKB accession:  O35310

Grouped By:  Matching UniProtKB accession

UniProtKB description:  Sulfotransferase that utilizes 3'-phospho-5'-adenylyl sulfate (PAPS) to catalyze the transfer of a sulfo group to position 3 of glucosamine residues in heparan (PubMed:9346953, PubMed:15060080). Catalyzes the rate limiting step in the biosynthesis of heparan sulfate (HSact) (PubMed:9346953, PubMed:15060080). This modification is a crucial step in the biosynthesis of anticoagulant heparan sulfate as it completes the structure of the antithrombin pentasaccharide binding site (PubMed:9346953, PubMed:15060080).
