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.
本发明一般涉及利用糖基转移酶可逆性合成核苷酸二磷酸(NDP)糖的材料和方法。本发明提供了改良反应可逆性并扩展糖供体特异性的工程糖基转移酶酶,与相应的非突变糖基转移酶酶相比,具有更好的反应可逆性和扩展的糖供体特异性。这些试剂提供了有利的NDP糖路线,用于随后在各种生物医学应用中使用,包括酶促和化学酶促糖随机化。
