Allgemeine Beschreibung

4-Nitrocatechol sulfate is an aromatic sulfate.

Anwendung

4-Nitrocatechol sulfate dipotassium salt has been used as a substrate in mucopolysaccharidoses VI (MPS VI) analysis. It has also been used to measure the activity of glycosaminoglycan (GAG)-degrading enzymes-arylsulfatase B, and exoglycosidases.

Substrate

Chromogenic sulfatase substrate.

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

A new, direct-colouring, metal precipitation method for the light microscopical demonstration of arylsulphatases A and B is described. It is based on the reducing capacity of nitrocatechol liberated by arylsulphatases from p-nitrocatechol sulphate. The reaction is carried out in Karnovsky-Roots'
