In enzymology, a chondro-6-sulfatase is an enzyme that catalyzes the chemical reaction 4-deoxy-beta-D-gluc-4-enuronosyl--N-acetyl-D-galactosamine 6-sulfate + H2O ⇌ {\displaystyle \rightleftharpoons } 4-deoxy-beta-D-gluc-4-enuronosyl--N-acetyl-D-galactosamine + sulfateThe 3 substrates of this enzyme are 4-deoxy-beta-D-gluc-4-enuronosyl--N-acetyl-D-galactosamine, 6-sulfate, and H2O, whereas its two products are 4-deoxy-beta-D-gluc-4-enuronosyl--N-acetyl-D-galactosamine and sulfate.
