The Substrate Specificity of Testicular Hyaluronidase and Its Use in Sequencing Chondroitin Sulfates
… units along chondroitin sulfate chains. The transglycosylation activity of the hyaluronidase was eliminated by use of excess levels of a second enzyme, (beta)-glucuronidase to remove all nonreducing terminal D-glucuronic acid residues from oligosaccharides present in the reaction mixture. …

A potential nutraceutical from Leuconostoc mesenteroides B-742 (ATCC 13146); production and properties
… hydrolysis of polysaccharides or synthesis by transglycosylation reactions. Oligosaccharides also can be produced using a Leuconostoc fermentation and restricting the polymer size by the addition of maltose. Maltose limits the dextransucrase reaction, yielding high concentrations of …

Purification and characterization of fungal β-glucosidase enzymes
… or accumulation of cellobiose is due to transglycosylation activity of NBG. According to activity (and 3D modelling) data, NBG may not be a true β-glucosidase belonging to the EC 3.2.1.21 (and having cellobiase activity). Further investigation of the possible substrate specificity and …

Chemical and chemoenzymatic syntheses of lantibiotics and other bioactive cyclic peptides
… was correlated with improved inhibition of transglycosylation during peptidoglycan biosynthesis. Chapter III describes a chemical approach to lanthipeptide production; solid-phase peptide synthesis was utilized to generate the first reported analogues of the potent lanthipeptide epilancin …

Purification and characterization of an endo-1,4-{u03B2}-D-glucanase and two exo-1,4-{u03B2}-D-glucanases from the cellulase system of Trichoderma reesei
… protein). This enzyme also possesses significant transglycosylation activity. When the three glucanases are combined in the proportion 60:25:15, cellobiohydrolase I (D): cellobiohydrolase II: endoglucanase (w/w) respectively, the resulting mixture exhibits activity identical to that of the crude …

Selektive Markierung von Glykokonjugaten mit modifizierten Donorzuckern als Substrate von Glykosyltransferasen und Glykosidasen
… that they are substrates of glycosidases. A transglycosylation of pNP-6-oxo-GalNAc with GlcNAc and subsequent chemical oxidation at the aldehyde moiety has led to one of the best so far known high affinity ligands for natural killer cell receptors.
