We demonstrated that β-(1-azulenyl)-L-alanine, a fluorescent pseudoisosteric analog of tryptophan, exhibits weak environmental dependence and thus allows for using weak intrinsic quenchers, such as methionines, to monitor proteinâprotein interactions while not perturbing them.
我们证明了β-(1-氮
芴基)-
L-丙氨酸(一种色
氨酸的荧光假异构体)对环境依赖性较弱,因此可以使用弱内源淬灭剂(如蛋
氨酸)来监测蛋白质-蛋白质相互作用,同时不会干扰它们。
