Application

4-Methylumbelliferyl N-acetyl-β-D-glucosaminide has been used as a fluorogenic substrate in the acidic chitinase activity assay. It has also been used to measure the total activity of β-N-acetylhexosaminidase (NAGase) in water sample filtrates.

Biochem/physiol Actions

4-Methylumbelliferyl-N-acetyl-β-D-glucosaminide (4-MUF-NAG) is a synthetic uncharged fluorogenic substrate for hexosaminidases. It consists of chitin monomer (N-acetyl-β-D-glucosaminide) and 4-methylumbelliferone (7-hydroxy-4-methylcoumarin) (4-MUF). 4-MUF-NAG is used for the detection and estimation of fungal growth by measuring the β-N-acetylhexosaminidase (NAGase) activity.

A new fluorogenic substrate, 4-methylumbelliferyl beta-D-glucosaminide, was used for the assay of acetyl CoA:glucosaminide N-acetyltransferase in chorionic villi, cultured villus cells, and amniocytes. Optimal conditions for the assay and the ranges of enzyme activity were established for the various types

Temperature-jump relaxation methods have been used to study the binding kinetics of fluorescent 4-methylumbelliferyl glycosides of N-acetyl-beta-D-glucosamine and its beta (1 leads to 4)-linked di- and trisaccharides with wheat germ agglutinin. The mono- and disaccharide derivatives yielded biexponential progress curves.
