摘要:
PROBLEM TO BE SOLVED: To provide a translation system of tRNAs and aminoacyl-tRNA synthetases capable of incorporating unnatural amino acids into proteins produced in a eubacteria host cell, such as E. coli, or a eukaryotic host cell such as yeast cell.SOLUTION: The translation system includes: (a) a first unnatural amino acid that is p-nitro-L-phenylalanine; (b) a first orthogonal aminoacyl-tRNA synthetase (O-RS); and(c) a first orthogonal tRNA (O-tRNA); wherein the first O-RS aminoacylates the first O-tRNA with the first unnatural amino acid with an efficiency that is at least 50% of the efficiency observed by translation system comprising the first unnatural amino acid, the first O-tRNA and an O-RS comprising a specific amino acid sequence.
