β-Galactosidase-catalyzed intramolecular transglycosylation

Komba, Shiro,Ito, Yukishige

, p. 8501 - 8505 (2001)

A novel transglycosylation strategy for efficient preparation of N-acetyllactosamine (Galβl→4GlcNAc, LacNAc) and sialyl LacNAc was developed using β-galactosidase from Bacillus circulans. In order to minimize the competing hydrolysis by forcing the enzyma
