Protein Structure
UniProt Annotation
Function Essential bifunctional enzyme that catalyzes both the N- deacetylation and the N-sulfation of glucosamine (GlcNAc) of the glycosaminoglycan in heparan sulfate. Modifies the GlcNAc-GlcA disaccharide repeating sugar backbone to make N-sulfated heparosan, a prerequisite substrate for later modifications in heparin biosynthesis. Has low deacetylase activity but high sulfotransferase activity (By similarity). {ECO:0000250}.
Subcellular Localization Golgi apparatus membrane {ECO:0000250}; Single-pass type II membrane protein {ECO:0000250}.
