Once activated under the glycosylation conditions, these donors afford the respective β-glycosides exclusively and in high yield. Since the trifluoroacetamido group is easily removed under mild conditions, the corresponding amino group can be appropriately derivatized, even in the presence of unprotected hydroxyl groups. Disaccharide libraries are designed, constructed and analyzed. The invention also relates to a process for synthesizing the glycosyl donor.

The present invention provides engineered glycosyltransferase enzymes characterized by improved reaction reversibility and expanded sugar donor specificity as compared to corresponding non-mutated glycosyltransferase enzymes. Such reagents provide advantageous routes to NDP sugars for subsequent use in a variety of biomedical applications, including enzymatic and chemo-enzymatic glycorandomization.
