4-Nitrophenyl N-acetyl-α-D-glucosaminide is used as a substrate for analysing β-hexoaminidase activity at 37°C and analysed at 405 nm.[2]
We found that the recombinant endo-beta-N-acetylglucosaminidase of Mucor hiemalis (Endo-M) expressed in Candida boidinii had the transglycosylation activity of transferring a bisecting hybrid-type oligosaccharide from an ovalbumin glycopeptide to the acceptor (p-nitrophenyl 2-acetamido-2-deoxy-beta-D-glucopyranoside) in a good yield of 43%.

Chitin catabolism in Vibrio furnissii comprises several signal transducing systems and many proteins. Two of these enzymes are periplasmic and convert chitin oligosaccharides to GlcNAc and (GlcNAc)2. One of these unique enzymes, a chitodextrinase, designated EndoI, is described here. The

The stereochemistry of the reaction catalysed by Serratia marcescens chitobiase was determined by HPLC separation of the anomers of N-acetylglucosamine produced during the hydrolysis of p-nitrophenyl N-acetyl-beta-d-glucosaminide (PNP-GlcNAc). In the early stages of the reaction, the beta-anomer was found to
