Predicted to enable [heparan sulfate]-glucosamine N-sulfotransferase activity and deacetylase activity. Predicted to be involved in heparan sulfate proteoglycan biosynthetic process, polysaccharide chain biosynthetic process. Predicted to act upstream of or within heparan sulfate proteoglycan biosynthetic process and heparin biosynthetic process. Predicted to be located in Golgi membrane. Predicted to be active in Golgi apparatus. Orthologous to human NDST2 (N-deacetylase and N-sulfotransferase 2).
