- [heparan sulfate]-glucosamine 3-sulfotransferase 1 activity
Catalysis of the reaction: 3'-phosphoadenylyl sulfate + [heparan sulfate]-glucosamine = adenosine 3',5'-bisphosphate + [heparan sulfate]-glucosamine 3-sulfate. The [heparan sulfate]-glucosamine 3-sulfate has a substrate consensus sequence of Glc(N2S>NAc)+/-6S GlcA GlcN2S*+/-6S GlcA>IdoA+/-2S Glc(N2S/NAc)+/-6S.
- nucleoside oxidase activity
Catalysis of the reactions: inosine + O2 = 9-riburonosylhypoxanthine + 2 H2O; (1a) 2 inosine + O2 = 2 5'-dehydroinosine + 2 H2O, and (1b) 2 5'-dehydroinosine + O2 = 2 9-riburonosylhypoxanthine + 2 H2O.
