  中华金莲花混杂C-糖基转移酶的分子和结构表征。

  摘要：

  在本文中，探索了药用植物金莲花（Trollius chinensis）中新的C-糖基转移酶（CGT）TcCGT1的催化混杂性。TcCGT1可以有效和区域特异性地催化36种黄酮和其他类黄酮的8 C糖基化，还可以催化多种酚的O糖基化。TcCGT1与尿苷二磷酸酯复合的晶体结构以1.85Å的分辨率测定。分子对接揭示了TcCGT1催化机制的新模型，该模型由底物的自发去质子化引发。宽大的装订袋说明了基材的混杂性，并且基材的装订姿势决定了C或O糖基化活性。位点定向诱变在两个残基（I94E和G284K）切换Ç -到Ò -glycosylation。TcCGT1是第一个具有晶体结构的植物CGT，并且是第一个描述的黄酮8- C-糖基转移酶。这为设计有效的糖基化生物催化剂提供了基础。
