Reaction: 4-deoxy-β-D-gluc-4-enuronosyl-(1→3)-N-acetyl-D-galactosamine 4-sulfate + H2O = 4-deoxy-β-D-gluc-4-enuronosyl-(1→3)-N-acetyl-D-galactosamine + sulfate
Other name(s): chondroitin-4-sulfatase; 4-deoxy-β-D-gluc-4-enuronosyl-(1,3)-N-acetyl-D-galactosamine-4-sulfate 4-sulfohydrolase
Systematic name: 4-deoxy-β-D-gluc-4-enuronosyl-(1→3)-N-acetyl-D-galactosamine-4-sulfate 4-sulfohydrolase
Comments: Also acts on the saturated analogue but not on higher oligosaccharides, nor any 6-sulfates.
