Protein geranylgeranylation is a type of post-translational modification that aids in the localization of proteins to the plasma member where they elicit cellular signals. To better understand the isoprenoid requirements of GGTase-I, a series of aryl-modified geranylgeranyl diphosphate analogs were synthesized and screened against mammalian GGTase-I. Of our seven-member library of compounds, six analogs
蛋白质香叶基香叶基化是一种翻译后修饰,有助于蛋白质定位在血浆中,在血浆中它们会引发细胞信号。为了更好地理解GGTase-I的类异戊二烯需求,合成了一系列芳基修饰的香叶基香叶基二磷酸二磷酸酯类似物,并针对哺乳动物的GGTase-I进行了筛选。在我们的七元化合物库中,六个类似物被证明是GGTase-I的底物,与 GGPP(k rel = 1.0)相比,6d的k rel = 1.93 。
