Applicazioni

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.

Azioni biochim/fisiol

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.

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.

1. Rat liver beta-N-acetylhexosaminidase was separated into several different molecular forms by DEAE-cellulose chromatography. 2. The subunit composition of the isoenzymes, as well as the similarities to human hexosaminidases, were determined by using the specific active alpha subunit substrate 4-methylumbelliferyl-beta-N-acetylglucosamine-6-sulphate.

This paper describes a comparison of the recently developed substrate 2-methoxy-4-(2'-nitrovinyl)-phenyl-2-acetamido-2-deoxy-beta-D-gluc opyranoside (MNP-GlcNAc) and the corresponding 4-methylumbelliferyl substrate (4-MU-GlcNAc) for the determination of urinary NAG. A good correlation (r = 0.977) was found between NAG activities in 366 urine samples

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
