Using a crude β-N-acetylhexosaminidase from Aspergillus oryzae both tri-N-acetylchitotriose (GlcNAc)3 (1,n=1) and tetra-N-acetylchitotetraose (GlcNAc4) (1,n=2) act respectively as both glycosyl donor and glycosyl acceptor to give product mixtures containing significant quantities of the corresponding penta- and hexasaccharides which are readily isolated and purified by charcoal-Celite chromatography.
Ring-opening glycosylation of a chitobiose oxazoline catalyzed by a non-chitinolytic mutant of chitinase

Ring-opening glycosylation of a chitobiose oxazoline was exclusively achieved by catalysis of a mutated chitinase that is only active for the glycosylation and not for chitinolysis.
