  • Publication number: 20210087572
    Abstract: The present invention provides modified aminoacyl-tRNA synthetases (ARSs) having increased reactivity with N-methyl amino acids compared to natural aminoacyl-tRNA synthetases. The modified aminoacyl-tRNA synthetases according to the present invention can aminoacylate tRNAs with their corresponding N-methyl-substituted amino acids such as N-methyl-phenylalanine, N-methyl-valine, N-methyl-serine, N-methyl-threonine, N-methyl-tryptophan and N-methyl-leucine more efficiently than natural aminoacyl-tRNA synthetases. The present invention enables a more efficient production of polypeptides containing N-methyl amino acids.

  • Publication number: 20200040372
    Abstract: An objective of the present invention is to provide methods of synthesizing peptides containing structurally diverse amino acids using cell-free translation systems, which can accomplish excellent translational efficiency as compared to conventional techniques (the conventional techniques being methods which involve preparing aminoacyl-tRNAs which do not have protecting groups outside the translation systems without using ARS, and then adding the prepared aminoacyl-tRNAs into translation systems). In the present invention, it was found that amino acid-containing peptides can be synthesized efficiently by protecting an amino acid linked to tRNA with an appropriate protecting group, and then performing the step of deprotecting the protecting group of the amino acid linked to tRNA and the step of peptide translation from a template nucleic acid in a cell-free translation system in parallel.

  • Publication number: 20190338050
    Abstract: When the initiation suppression method was used for translation of a peptide having at its N terminus an amino acid residue carrying a thiol group near its amino group with specific protecting groups being introduced to the thiol group and the amino group, it was found that not only the probability of initiation of amino acid translation reaction was improved, but also production of cleaved peptides was suppressed and translation efficiency and purity were improved. Furthermore, it was found that it is possible to efficiently promote the cyclization reaction of the peptide through amide bond formation. Based on these findings, the inventors discovered novel methods for preparing complexes between nucleic acids and peptides containing various unnatural amino acids and having an amide bond-mediated cyclized portion.

  • Patent number: 9890683
    Abstract: It is an object to make it possible to burn and remove particulate matter without generating runaway even if the particulate matter is excessively accumulated at the time of regeneration of an exhaust gas purification device. A common rail engine and the exhaust gas purification device placed in an exhaust gas path of the engine are provided. A plurality of regeneration controls for burning and removing the particulate matter accumulated in the exhaust gas purification device can be executed. The plurality of regeneration controls include at least non-operation regeneration control for raising exhaust gas temperature by combining post injection (E) and predetermined high speed rotation speed, and recovery regeneration control which can be executed when the non-operation regeneration control fails. In the non-operation regeneration control and the recovery regeneration control, the engine is driven exclusively for burning and removing the particulate matter.
