Abstract
This disclosure provides engineered aminoacyl tRNA synthetases and tRNAs for efficient production of proteins containing non-standard amino acids. These engineered orthogonal tRNA (O-tRNA)/orthogonal aminoacyl tRNA synthetase (O-RS) pairs, i.e., Orthogonal Translation Systems (OTSs) can be used to incorporate a non-standard amino acid in a specific position in a growing polypeptide in response to a selector codon that is recognized by the engineered tRNA.
