    • This invention provides compositions and methods for producing translational components that expand the number of genetically encoded amino acids in vertebrate cells. The components include orthogonal tRNA's, orthogonal aminoacyl-tRNA synthetases, orthogonal pairs of tRNA's/synthetases and unnatural amino acids. Proteins and methods of producing proteins with unnatural amino acids in vertebrate cells are also provided. The present invention provides vertebrate cells with translation components, e.g., pairs of orthogonal aminoacyl-tRNA synthetases (O-RSs) and orthogonal tRNA's (O-tRNA's) and individual components thereof, that are used in vertebrate protein biosynthetic machinery to incorporate an unnatural amino acid in a growing polypeptide chain, in a vertebrate cell.
    • 本发明提供用于生产翻译成分的组合物和方法,其扩展脊椎动物细胞中遗传编码氨基酸的数目。 组分包括正交tRNA,正交氨酰-tRNA合成酶,tRNA /合成酶和非天然氨基酸的正交对。 还提供了在脊椎动物细胞中产生具有非天然氨基酸的蛋白质的蛋白质和方法。 本发明提供具有翻译成分的脊椎动物细胞,例如正交氨基-tRNA合成酶(O-RS)和正交tRNA(O-tRNA)及其各自成分的对,其用于脊椎动物蛋白质生物合成机制以掺入非天然氨基 在生长的多肽链中,在脊椎动物细胞中。
