Evolution of multiple, mutually orthogonal prolyl-tRNA synthetase/tRNA pairs for unnatural amino acid mutagenesis in Escherichia coli

The site-specific incorporation of unnatural amino acids (UAAs) into proteins in living cells relies on an engineered tRNA/aminoacyl-tRNA synthetase (tRNA/aaRS) pair, orthogonal to the host cell, to deliver the UAA of choice in response to a unique nonsense or frameshift codon. Here we report the ge...
