Identification
HMDB Protein ID HMDBP11854
Secondary Accession Numbers None
Name Bifunctional heparan sulfate N-deacetylase/N-sulfotransferase 2
Synonyms
  1. Glucosaminyl N-deacetylase/N-sulfotransferase 2
  2. N-heparan sulfate sulfotransferase 2
  3. NDST-2
  4. N-HSST 2
Gene Name NDST2
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. Plays a role in determining the extent and pattern of sulfation of heparan sulfate.
Pathways
  • Glycosaminoglycan biosynthesis - heparan sulfate / heparin
  • heparan sulfate biosynthesis
  • heparin biosynthesis
