Arylsulfatase A hydrolyzes the artificial chromogenic substrate 4-nitrocatechol-sulfate at 0 degree C at a rate of 24% of that at 37 degrees C whereas arylsulfatase B is almost inactive at 0 degree C. Based on this observation, a simple assay

Sulfatases contain an active site formylglycine residue that is generated by post-translational modification. Crystal structures of two lysosomal sulfatases revealed significant similarity to the catalytic site of alkaline phosphatase containing a serine at the position of formylglycine. To elucidate the
