The transglycosylation activity of endo-β-N-acetylglucosaminidase from Arthrobacter protophormiae was used for the enzymatic synthesis of novel oligosaccharides. When (Man)6(GlcNAc)2Asn was used as a substrate for the transglycosylation, (Man)6GlcNAc-Glc, (Man)6GlcNAc-Man, (Man)6GlcNAc-chitobiose, and (Man)6GlcNAc-gentiobiose were synthesized. Their structures were identified by HPLC, ion spray mass spectrometry, and digestion with glycosidases Endo-β-N-acetylglucosaminidases hydrolyzed the pyridylamino derivatives of these oligosaccharides.
