engineered to generate an active thioglycoligase that is able to catalyse the formation of numerous S-glucuronides. Its X-ray structure analysis indicated the ability of the biocatalyst to bind aromatic thiol acceptors for S-glycosylation. Noteworthily, the DtGlcA mutant was found to be the first thioligase that is able to use a natural sugar donor different from the widely used synthetic para-nitrophenyl
将来自嗜热纤维单胞菌的β- D-葡糖醛酸糖苷酶Dt GlcA工程化以产生能够催化多种S-葡糖醛酸苷的形成的活性硫糖寡糖酶。其X射线结构分析表明生物催化剂结合芳族硫醇受体进行S-糖基化的能力。值得注意的是,发现Dt GlcA突变体是第一个能够使用与广泛使用的合成对硝基苯基糖苷不同的天然糖供体的硫解酶。
