NDST3

Bifunctional heparan sulfate N-deacetylase/N-sulfotransferase 3 is an enzyme that in humans is encoded by the "NDST3" gene. It catalyses the reaction:3'-phosphoadenylyl sulfate + α--glucosaminyl-[heparan sulfate] = adenosine 3',5'-bisphosphate + 2 H + "N"-sulfo-α--glucosaminyl-[heparan sulfate]This is a step in the production of heparin.
Clinical significance.
Mutations in "NDST3" have been linked to schizophrenia.
