The invention relates to orthogonal pairs of tRNAs and aminoacyl-tRNA synthetases that can incorporate unnatural amino acids into proteins produced in eubacterial host cells such as E.coli, or in a eukaryotic host such as a yeast cell. The invention provides, for example but not limited to, novel orthogonal synthetases, methods for identifying and making the novel synthetases, methods for producing proteins containing unnatural amino acids, and translation systems.
本发明涉及正交对 tRNA 和氨基酰-tRNA 合成酶,它们可以将非天然氨基酸掺入到在真细菌宿主细胞(如大肠杆菌)或真核细胞宿主(如酵母细胞)中生产的蛋白质中。本发明提供了例如但不限于新型正交合成酶、鉴定和制造新型合成酶的方法、生产含有非天然氨基酸的蛋白质的方法以及翻译系统。
