    摘要: The invention relates to orthogonal pairs of tRNAs and aminoacyl-tRNA synthetases that can incorporate unnatural amino acids that comprise a 1,2 aminothiol group into polypeptides. The invention provides translation systems in which polypeptides comprising unnatural amino acids that comprise a 1,2 aminothiol group can be produced. The invention also provides methods for producing polypeptides containing unnatural amino acids that comprise a 1,2 aminothiol group. Also provided by the invention are compositions comprising orthogonal aminoacyl-tRNA synthetases that preferentially aminoacylate a cognate orthogonal tRNA with unnatural amino acids that comprise a 1,2 aminothiol group. The invention provides methods for the synthesis of the unnatural amino acid 2-amino-3-(4-(2-amino-3-mercaptopropan-amido)phenyl)-propanoic acid.
