A mutant yeast phenylalanine transfer RNA (ytRNA^(Phe)_(AAA)) containing a modified (AAA) anticodon was generated to explore the feasibility of breaking the degeneracy of the genetic code in Escherichia coli. By using an E. coli strain co-transformed with ytRNA^(Phe)_(AAA) and a mutant yeast phenylalanyl-tRNA synthetase, we demonstrate efficient replacement of phenylalanine (Phe) by L-3-(2-naphthyl)alanine (Nal) at UUU, but not at UUC codons.
