    摘要: A non-natural protein having at least one ester bond in its polypeptide main chain is synthesized by using an in vivo translation system in a ribosome. The following components (a) to (c) are expressed in a cell or an cell extraction solution in the presence of an α-hydroxy acid: (a) an aminoacyl-tRNA synthetase which can activate the α-hydroxy acid; (b) suppressor tRNA which can bind to the α-hydroxy acid in the presence of the aminoacyl-tRNA synthetase; and (c) a gene encoding a desired protein having a nonsense mutation or a frame-shift mutation at a desired site.

    摘要: A polypeptide according to the present invention includes: an altered polypeptide obtained by altering an ArgRS, a CysRS, a MetRS, a GlnRS, a GluRS, a LysRS, a TyrRS, or a TrpRS so that an unnatural amino acid is recognized; and an editing polypeptide derived from a PheRS, a LeuRS, an IleRS, a ValRS, an AlaRS, a ProRS, or a ThrRS, the editing polypeptide having been either inserted between a Rossman-fold N domain and a Rossman-fold C domain that exist in the altered polypeptide, or bound to an N terminal of the altered polypeptide. Thus provided are a new aaRS that exhibits high substrate specificity to an unnatural amino acid and a technique that involves the use of such an aaRS.

    摘要: The present invention provides a novel method of producing a recombinant bacterium for production of a non-natural protein, including: (1) expressing tRNA in a bacterium, which tRNA recognizes UAG codon; (2) expressing an aminoacyl-tRNA synthetase in the bacterium, which aminoacyl-tRNA synthetase acylates the tRNA with a non-natural amino acid or an α-hydroxy acid; (3) (i) introducing a DNA construct into the bacterium, which DNA construct is for expressing, in the absence of a release factor for terminating translation at UAG codon, a function of at least one gene selected from the group consisting of genes each of which loses its function when a gene that codes for the release factor is defective and/or introducing an alteration into said at least one gene in a chromosome of the bacterium, which alteration is for expressing the function of said at least one gene in the absence of the release factor; and (4) causing the gene that codes for the release factor in the bacterium to be defective.
