摘要:
Compositions and methods of producing vaccines, including methods wherein whole organism vaccines are provided with limited replication abilities, thereby increasing vaccine safety and efficacy, through the use of non-natural, unnatural, or non-naturally encoded amino acids.
摘要:
Compositions and methods of producing components of protein biosynthetic machinery that include orthogonal tRNA’s, orthogonal aminoacyl- tRNA synthetases, and orthogonal pairs of tRNA’s /synthetases are provided. Methods for identifying these orthogonal pairs are also provided along with methods of producing proteins using these orthogonal pairs.
摘要:
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.
摘要:
Disclosed herein are methods of detecting non-natural amino acids and polypeptides that include at least one non-natural amino acid. The non-natural amino acids, by themselves or as a part of a polypeptide, can include a wide range of functionalities, including but not limited to oxime, carbonyl, and/or hydroxy lamine groups. Also disclosed herein are non-natural amino acid polypeptides that are further modified post-translationally, and methods for detecting such polypeptides.
