    摘要: Method for incorporating a lysine derivative (particularly an Nε-benzyloxycarbonyl-lysine (Z-Lys) derivative) having useful functional group such as heavy atom, selenium, reactive functional group, fluorescent group or crosslinker, which is suitable as a non-natural amino acid, into a desired protein in a site-specific manner. A mutant pyrrolysyl-tRNA synthetase has substitution of at least one amino acid residue selected from tyrosine residue at position 306, leucine residue at position 309 and cysteine residue at position 348 each constituting a pyrrolysine-binding site in the amino acid sequence for pyrrolysyl-tRNA synthetase of SEQ ID NO:2. The substitution of the amino acid residue is: of tyrosine residue at position 306 by glycine or alanine residue, of leucine residue at position 309 by glycine or alanine residue, and/or of a cysteine residue at position 348 by valine, serine or alanine residue.

    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.
