to enable a protein to enter the cytosol of a mammalian cell. Diazo compounds derived from (p-methylphenyl)glycine were screened for the ability to esterify the green fluorescent protein (GFP) in an aqueous environment. Esterification of GFP with 2-diazo-2-(p-methylphenyl)-N,N-dimethylacetamide was efficient. The esterified protein entered the cytosol by traversing the plasma membrane directly, like
显示用疏水部分包覆其羧基可使蛋白质进入哺乳动物细胞的胞质溶胶。筛选源自(对甲基苯基)甘氨酸的重氮化合物在水性环境中酯化绿色荧光蛋白 (GFP) 的能力。GFP 与 2-重氮-2-(p-甲基苯基)-N,N-二甲基乙酰胺的酯化是有效的。酯化的蛋白质像小分子前药一样直接穿过质膜进入细胞质。与前药一样,新生酯是内源性酯酶的底物,可再生天然蛋白质。因此,酯化可以提供一种将天然蛋白质递送到细胞溶质的通用方法。
