We just click: Genetic incorporation of a cyclopropene amino acid CpK (see scheme) site‐specifically into proteins in E. coli and mammalian cells was achieved using an orthogonal aminoacyl‐tRNA synthetase/tRNACUA pair (CpKRS/MbtRNACUA). Cyclopropene exhibited fast reaction kinetics in the photoclick reaction and allowed rapid (ca. 2 min) labeling of proteins.
我们只需点击:使用正交氨酰-tRNA 合成酶/tRNA CUA对(CpKRS/ Mb tRNA CUA),将环丙烯氨基酸 CpK(参见方案)基因位点特异性地整合到大肠杆菌和哺乳动物细胞中的蛋白质中。环丙烯在光点击反应中表现出快速反应动力学,并允许快速(约 2 分钟)标记蛋白质。
