 Heparosan-N-sulfate-glucuronate 5-epimerase

Heparosan-N-sulfate-glucuronate 5-epimerase (, "heparosan epimerase", "heparosan-N-sulfate-D-glucuronosyl 5-epimerase", "C-5 uronosyl epimerase", "polyglucuronate epimerase", "D-glucuronyl C-5 epimerase", "poly[(1,4)-beta-D-glucuronosyl-(1,4)-N-sulfo-alpha-D-glucosaminyl] glucurono-5-epimerase") is an enzyme with systematic name "poly((1->4)-beta-D-glucuronosyl-(1->4)-N-sulfo-alpha-D-glucosaminyl) glucurono-5-epimerase".This enzyme catalyses the following chemical reaction

This enzyme acts on D-glucuronosyl residues adjacent to sulfated D-glucosamine units in the heparin precursor.
