EC 5.1.3.17
Common name :Heparosan-N-sulfate-glucuronate 5-epimerase

Systematic name :Poly((1->4)-beta-D-glucuronosyl-(1->4)-N-sulfo-alpha-D-glucosaminyl) glucurono-5-epimerase

Other names :D-glucuronyl C-5 epimerase
C-5 uronosyl epimerase
Heparosan epimerase
Heparosan-N-sulfate-D-glucuronosyl 5-epimerase
Polyglucuronate epimerase
Poly((1,4)-beta-D-glucuronosyl-(1,4)-N-sulfo-alpha-D-glucosaminyl) glucurono-5-epimerase
Comments :Acts on D-glucuronosyl residues adjacent to sulfated D-glucosamine units in the heparin precursor. Not identical with EC 5.1.3.19 chondroitin-glucuronate 5-epimerase. Acts on D-glucuronosyl residues adjacent to sulfated D-glucosamine units in the heparin precursor. Not identical with EC 5.1.3.19.
