Actions biochimiques/physiologiques

4-Nitrophenyl N-acetyl-α-D-galactosaminide serves as a chromogenic synthetic substrate for lysosomal enzyme α-N-acetylgalactosaminidase to perform enzyme assays. Upon cleavage the substrate forms a yellow color solution of p-nitrophenol that can be measured at 400nm at pH 10.6.

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

Levels and isoenzyme profiles of beta-hexosaminidase were compared in extracts from normal ovarian and ovarian epithelial tumors. The specific activities of beta-hexosaminidase were significantly (P less than 0.001) higher in malignant than in normal ovarian tissues. The enzyme levels of

Chick embryo chondrocyte microsomes containing intact Golgi vesicles took up 3'-phosphoadenosine-5'-phospho[35S]sulfate ([35S]PAPS) in a time- and temperature-dependent, substrate-saturable manner. When [35S]PAPS and p-nitrophenyl-N-acetyl-beta-D-galactosaminide (pNP-GalNAc) were added to the incubation in the absence of detergent, the microsomes catalyzed the transfer of

The beta-N-acetylhexosaminidase from Aspergillus oryzae catalysed the transfer of beta-D-N-acetylgalactosaminyl residues from p-nitrophenyl beta-D-N-acetylglucosaminide on to disaccharide acceptors consisting of thioethyl glycosides of alpha-D-Glc-(1-->4)-beta-D-Glc, beta-D-Glc-(1-->4)-beta-D-Glc and beta-D-Glc-(1-->6)-beta-D-Glc. The principle of 'anomeric control' was exemplified by the results which showed that
