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.
一种在
多肽文库中筛选与目标物质结合的非标准
多肽化合物的方法,包括以下步骤:(i) 制备非标准肽库,其中通过无细胞(体外)翻译系统将特殊(非标准)
氨基酸随机加入到肽序列中,该系统包括由特殊(非标准)
氨基酸酰化的 tRNA;(ii) 将获得的肽库与目标物质接触;以及 (iii) 挑选出与目标物质结合的非标准肽作为活性肽。
