Opis

General description

4-Methylumbelliferyl sulfate (4MUS), a general substrate,[1] is a polar metabolite of 4-methylumbelliferone (4MU).[2]

Application

4-Methylumbelliferyl sulfate potassium salt has been used as a substrate in coupled fluorescence sulfotransferase assay to regenerate 3′-phosphoadenosine 5′-phosphosulfate (PAPS) from 3′-phosphoadenosine 5′-phosphate for cerebroside sulfotransferase (CST) enzyme activity measurements.[3] It has also been used as a substrate in arylsulfatase assay/4-methylumbelliferyl sulfate (4-MUS) assay to test the enzymatic activity of the protein-bead complex.[1]

Biochem/physiol Actions

4-Methylumbelliferyl sulfate (4MUS) is capable of undergoing desulfation and involve in futile cycling with 4MU.[2] It can be utilized to measure the arylsulfatase activity of several sulfatases.[1]
