HS3ST1, Human (sf9, His)

The HS3ST1 protein utilizes PAPS to crucially catalyze the transfer of sulfate to position 3 of the glucosamine residue in heparan sulfate (HS), representing the rate-limiting step in HS biosynthesis. This activity is essential for the formation of the anticoagulant heparan sulfate and completion of the antithrombin pentasaccharide binding site. HS3ST1 Protein, Human (sf9, His) is the recombinant human-derived HS3ST1 protein, expressed by Sf9 insect cells , with N-His labeled tag.
