suitable for copper-catalyzed azide-alkyne cycloaddition, metathesis, and inverse-electron-demand Diels-Alder (IEDDA) reactions. A 10-mer tryptophan-containing macrocyclic peptide was tailored by AcyF, and the resulting modified peptide was successfully labelled with a tetrazine–fluorescein conjugate by IEDDA.
用 22 种非天然焦磷酸盐筛选了 N1-色氨酸异戊二烯基转移酶 AcyF 的混杂性,这些焦磷酸盐表现出适合铜催化叠氮-炔环加成、复分解和逆电子需求 Diels-Alder (IEDDA) 反应的反应基团。 AcyF 定制了含有色氨酸的 10 聚体大环肽,并通过 IEDDA 成功地用四嗪-荧光素缀合物标记了所得修饰肽。
