additional information | the enzyme acts preferentially on an ester sulfate on the C4 position of the GalNAc residue at the reducing end under mild incubation conditions, but also releases a sulfate group under harsh conditions from the C4 position of the GalNAc residue at the internal positions of the hexasaccharide chains, unless the GalNAc residue has another ester sulfate on its C6 position | Proteus vulgaris | ? | - |
