General description

4-Nitrophenyl N-acetyl-β-D-galactosaminide is a chromogenic substrate for enzymes N-acetyl-β-D-galactosaminidase and N-Acetyl-β-D-hexosaminidase. It is membrane-permeable and serves as a substrate for the enzyme 6-sulfotransferase in Golgi vesicles.

Application

4-Nitrophenyl N-acetyl-β-D-galactosaminide has been used:
  • as a synthetic substrate in the glycosyl hydrolase assay of Yersinia pseudotuberculosis protein
  • as a substrate in -β-hexosaminidase assay in adenocarcinomic human alveolar basal epithelial cells A549
  • as a substrate for N-acetyl-β-D-galactosaminidase assay in rat kidney tissue extracts

Beta-N-acetyl-D-glucosaminidase (NAGase, EC.3.2.1.52), which catalyzes the cleavage of N-acetylglucosamine polymers, is a composition of chitinase and cooperates with endo-chitinase and exo-chitinase to disintegrate chitin into N-acetylglucosamine (NAG). In this investigation, A NAGase from green crab (Scylla serrata) was purified and
