Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a new transglycosidase and a transglycosylation method. SOLUTION: The new transglycosylation method comprises the following procedure. In the presence of a protein having endo-α-N-acetyl galactosaminidase activity and transglycosylation activity, a reaction is carried out to transfer a galactosyl β1→3N-acetyl galactosaminyl α-group from a sugar chain donor containing the galactosyl β1→3N-acetyl galactosaminyl α-group to a sugar chain acceptor. This method is useful in the industries utilizing the glycotechnology, for example, in producing saccharides and glycoproteins. COPYRIGHT: (C)2007,JPO&INPIT
