摘要:
Compositions and methods of producing components of protein biosynthetic machinery that include orthogonal leucyl-tRNAs, orthogonal leucyl-aminoacyl-tRNA synthetases, and orthogonal pairs of leucyl-tRNAs/synthetases, which incorporate photoregulated amino acids, OMe-L-tyrosine, α-aminocaprylic acid, or o-nitrobenzyl cysteine into proteins are proteins are provided in response to an amber selector codon. Methods for identifying these orthogonal pairs are also provided along with methods of producing proteins with a photoregulated amino acid, Ome-L-tyrosine, α-aminocaprylic acid, or o-nitrobenzyl cysteine using these orthogonal pairs.
摘要:
The invention relates to orthogonal pairs of tRNAs and aminoacyl-tRNA synthetase that can incorporate unnatural amino acid 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.

摘要:
Translation systems and other compositions including orthogonal aminoacyl tRNA-synthetases that preferentially charge an orthogonal tRNA with an iodinated or brominated amino acid are provided. Nucleic acids encoding such synthetases are also described, as are methods and kits for producing proteins including heavy atom-containing amino acids, e.g., brominated or iodinated amino acids. Methods of determining the structure of a protein, e.g., a protein into which a heavy atom has been site-specifically incorporated through use of an orthogonal tRNA/aminoacyl tRNA-synthetase pair, are also described.
