摘要： In the method for introducing a noncanonical amino acid residue into a desired position in a protein, the structure of tRNA is so modified as to have improved affinity for aminoacyl-tRNA synthetase or improved specificity to aminoacyl-tRNA synthetase. An unnatural base is contained at any position in tRNA, whereby the efficiency of aminoacylation of the tRNA with a noncanonical amino acid can be improved.

摘要： Producing proteins incorporating non-natural amino acids can involve introducing genes into and knocking inherent genes out of eukaryote-type cells. Genes to be introduced include genes encoding eukaryote-type aminoacyl tRNA synthetase mutants having enhanced specificity to non-natural amino acids, compared with specificity to similar natural amino acids, and tRNA genes for non-natural amino acids capable of binding to the non-natural amino acids in the presence of the eukaryote-type aminoacyl tRNA synthetase mutants. Inherent genes to be knocked out include genes encoding aminoacyl tRNA synthetase having specificity to natural amino acids and tRNA genes capable of binding to the natural amino acids in the presence of the inherent aminoacyl tRNA synthetase.

摘要： It is intended to provide an extract, kit and a process for synthesizing a protein in a cell-free system. The extract is characterized by being prepared from mutant Escherichia coli cells having a mutation in the ribosomal protein S12 gene. In a preferred embodiment, the mutation is such a mutation as conferring a resistance or dependence to streptomycin on E. coli whereby the reading efficiency of mRNA codon on ribosomes can be improved and thus the protein productivity can be elevated.
