HMDB Protein ID HMDBP11855
Secondary Accession Numbers None
Name Bifunctional heparan sulfate N-deacetylase/N-sulfotransferase 3
  1. Glucosaminyl N-deacetylase/N-sulfotransferase 3
  2. N-heparan sulfate sulfotransferase 3
  3. NDST-3
  4. hNDST-3
  5. N-HSST 3
Gene Name NDST3
Protein Type Unknown
Biological Properties
General Function Not Available
Specific 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 high deacetylase activity but low sulfotransferase activity.
