Abstract
A novel strategy for the incorporation of nonnatural amino acids into proteins was developed by using five-base codon-anticodon pairs. The streptavidin mRNA containing five-base codon CGGUA and the chemically aminoacylated tRNA with five-base anticodon UACCG were prepared, and added into E. coli in vitro translation system. As a result, the nonnatural amino acid was successfully incorporated into desired position of the protein. Other five-base codons CGGN1N2, where N1 and N2 indicate one of four nucleotides, were also available for the incorporation of the nonnatural amino acid.
