Description

General description

4-Methylumbelliferyl N-acetyl-β-D-glucosaminide (4-MUF-NAG) contains chitin monomer, N-acetyl-D-glucosamine (NAG) and a 4-methylumbelliferone (7-hydroxy-4-methylcoumarin) (4-MUF) moiety.

Application

4-Methylumbelliferyl N-acetyl-β-D-glucosaminide has been used as a substrate for assaying

• β-N-acetylglucosaminidase (NAGase) from soil samples
• chitinase from Fusarium oxysporum using fluorimetric assay
• β-N-acetylhexosaminidases from Arabidopsis thaliana roots and leaves samples

Biochem/physiol Actions

4-Methylumbelliferyl N-acetyl-β-D-glucosaminide (4-MUF-NAG) is a synthetic fluorogenic substrate for N-acetyl-β-D-glucosaminidase (NAGase). The enzyme functionality is assessed by its ability to hydrolyze the N-acetyl-D-glucosamine (NAG) residue in 4-MUF-NAG. 4-MUF-NAG is also a substrate for Chitinase and N-acetylhexosaminidase.

Substrates

Fluorogenic substrate for β-N-acetylhexosaminidase
