abstract：:Fucosyloligosaccharides have great therapeutic potential. Here we present a new route for synthesizing a Fucalpha1,2Gal linkage by introducing glycosynthase technology into 1,2-alpha-l-fucosidase. The enzyme adopts a unique reaction mechanism, in which asparagine-423 activated by aspartic acid-766 acts as a base while...
