Opis ogólny

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

Zastosowanie

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. 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.

Działania biochem./fizjol.

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

Futile cycling between 4-methylumbelliferone and its sulfate and glucuronide conjugates was examined in the single-pass perfused rat liver preparation. The steady-state hepatic extraction ratio of 4-methylumbelliferone was found to be high (0.97) at a low input concentration of 0.005 mumol/L

A sensitive fluorometric assay was developed for alcohol sulfotransferase (AST). This was the first continuous fluorometric assay reported for AST. It used 3'-phosphoadenosine 5'-phosphosulfate regenerated from 3-phosphoadenosine 5'-phosphate by a recombinant phenol sulfotransferase (PST) using 4-methylumbelliferyl sulfate as the sulfuryl
