为了获得特异性蛋白质检测的分子探针,我们利用基于gp 10的硫醚化(10 BASED-T)技术,在T7噬菌体上合成了多样性丰富的荧光探针库。从文库中筛选出一个显色性和开启性较好的探针,并获得了其与靶点特异性结合的理化性质。结合分析的荧光发射滴定,等温滴定量热法(ITC),和定量饱和转移差(STD)NMR测量,然后在计算机对接模拟,合理化的配体-蛋白质相互作用的最合理的几何形状。
To obtain a molecular probe for specific protein detection, we have synthesized fluorogenic probe library of vast diversity on bacteriophage T7 via the gp10 based-thioetherificaion (10BASEd-T). A remarkable color-changing and turning-on probe was selected from the library, and its physicochemical properties upon target-specific binding were obtained. Combination analyses of fluorescence emission titration, isothermal titration calorimetry (ITC), and quantitative saturation-transfer difference (STD) NMR measurements, followed by in silico docking simulation, rationalized the most plausible geometry of the ligand–protein interaction.
