Glycosidase‐Catalyzed Synthesis of Fucosyl Di‐ and Trisaccharide Derivatives Using α‐l‐Fucosidase fromAlcaligenes sp
摘要:
p-Nitrophenyl glycosides of di-and trisaccharides containing a (1-->2)-, (1-->3)-, (1-->4)-, or (1-->6)-linked alpha-L-fucosyl group were synthesized using the transglycosylation reaction mediated by alpha-L-fucosidase from Alcaligenes sp. with p-nitrophenyl glycosides of N-acetyllactosamine, lactose, D-GlcNAc, and D-Glc as acceptors. The enzymatic process for preparing these compounds is simple, and the yield is sufficiently high to make the method practical.
