The present invention generally relates to materials and methods for exploiting glycosyltransferase reversibility for nucleotide diphosphate (NDP) sugar synthesis. 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.
