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.

A total of 101 strains of bacteria from environmental and clinical sources, most of which were gram negative, were tested for chitobiase activity by using a filter paper spot test with 4-methylumbelliferyl-N-acetyl-beta-D-glucosaminide as the substrate. The results were compared with
