Chaperoning an enzyme: Fluorosugar glycosidase inactivators with tunable phosphorus‐based leaving groups react quickly with the catalytic nucleophile in β glucocerebrosidase (blue circle; Bn=benzyl). In Western blot analysis, Gaucher patient cells treated with these inactivators show increased intracellular levels of mutant enzyme, presumably because of increased transit from the endoplasmic reticulum
陪伴酶:具有可调磷基离去基团的氟糖糖苷酶灭活剂与 β 葡糖脑苷脂酶中的催化亲核试剂快速反应(蓝色圆圈;Bn=苄基)。在蛋白质印迹分析中,用这些灭活剂处理的戈谢患者细胞显示出细胞内突变酶水平增加,可能是因为从内质网(淡蓝色)到溶酶体(淡粉色)的转运增加。
