This invention provides compositions and methods for producing translational components that expand the number of genetically encoded amino acids in eukaryotic cells. The components include orthogonal tRNAs, orthogonal aminoacyl-tRNA synthetases, orthogonal pairs of tRNAs/synthetases and unnatural amino acids. Proteins and methods of producing proteins with unnatural amino acids in eukaryotic cells are also provided.
本发明提供了用于生产转录组件的组合物和方法,这些组合物可以扩大真核细胞中遗传编码的
氨基酸数量。这些组件包括正交的tRNA,正交的
氨酰-tRNA合成酶,正交的tRNA/合成酶对和非天然
氨基酸。本发明还提供了在真核细胞中产生带有非天然
氨基酸的蛋白质和制造蛋白质的方法。
