We characterized the first plant cycloartane glycosyltransferase AmGT8 from A. membranaceus. Its mutants A394F, A394D, and T131V were discovered using semi-rational design, which showed specific 6-O, 3-O, and 2′-O glycosylation activities, respectively. This study uncovered a conserved residue critical for the regiospecificity of plant glycosyltransferases.
我们对来自A. membranaceus的第一个植物环阿坦糖基转移酶 AmGT8 进行了表征。其突变体 A394F、A394D 和 T131V 是使用半理性设计发现的,它们分别显示出特定的 6- O、3 - O和 2' - O糖基化活性。这项研究发现了一个对植物糖基转移酶的区域特异性至关重要的保守残基。
