Ｎ−メチルアミノ酸およびその他の特殊アミノ酸を含む特殊ペプチド化合物ライブラリーの翻訳構築と活性種探索法

摘要

A method for screening a non-standard peptide compound in the peptide library that binds to the target substance, comprising the steps: (i) preparing a non-standard peptide library wherein a special (non-standard) amino acid is randomly incorporated into the peptide sequence by a cell-free ( in vitro ) translation system comprising a tRNA acylated by a special (non-standard) amino acid; (ii) bringing the obtained peptide library in contact with a target substance; and (iii) selecting a non-standard peptide that binds to the target substance as an active peptide.
