Publication number: 20200040372Abstract: 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.Type: ApplicationFiled: January 31, 2018Publication date: February 6, 2020Inventors: Shota TANAKA, Atsushi OHTA, Tetsuo KOJIMA

Publication number: 20190338050Abstract: 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.Type: ApplicationFiled: March 3, 2017Publication date: November 7, 2019Applicant: CHUGAI SEIYAKU KABUSHIKI8 KAISHAInventors: Kazuhiko NAKANO, Atsushi OHTA, Takeo IIDA, Hitoshi IIKURA
