Hazard Information

Description

4-Methylumbelliferyl-β-D-Glucopyranoside (4-MUG) is a fluorogenic substrate of β-glucosidase and β-glucocerebrosidase (also known as glucosylceramidase). In addition to its use in characterizing novel β-glucosidases, 4-MUG is used in assays to evaluate deficiency in β- glucocerebrosidase activity related to Gaucher disease. Hydrolysis of 4-MUG releases the fluorescent product 4-MU, which has an emission maximum at 445-454 nm. The excitation maximum for 4-MU is pH-dependent: 330, 370, and 385 nm at pH 4.6, 7.4, and 10.4, respectively.

Chemical Properties

White Powder

Uses

A fluorogenic substrate in the assay of ?-glucosidase. Fluorescence: max. Abs. 316nm; max. Em. 372nm; e x 10-3: 15

Definition

ChEBI: A beta-D-glucoside having a 4-methylumbelliferyl substituent at the anomeric position.

Biochem/physiol Actions

4-Methylumbelliferyl β-D-glucopyranoside is a synthetic enzymatic substrate for glycosidase. It has been used as substrate for the β- glucosidase from enterococci.

Purification Methods

4-Methylumbellifer-7-yl--Dglucopyranoside crystallises as the half hydrate from hot H2O. [Constantzas & Kocourek Collect Czech Chem Commun 24 1099 1959, De Re et al.
