The invention relates to genetic incorporation of 2,3-diamino propionic acid (DAP) into polypeptides, to unnatural amino acids comprising DAP, to a tRNA synthetase for charging tRNA with unnatural amino acids comprising DAP, and to methods of using the resulting polypeptides, for example in capturing substrates and/or intermediates in enzymatic reactions. The invention also relates to compounds of formula (I) or (II): or salts, solvates, tautomers, isomers or mixtures thereof.
该发明涉及将2,3-二氨基丙酸(DAP)基因合成到多肽中,涉及包含DAP的非天然氨基酸,涉及用于将tRNA充电为包含DAP的非天然氨基酸的tRNA合成酶,以及使用所得多肽的方法,例如在捕获酶反应中的底物和/或中间体。该发明还涉及以下化合物的公式(I)或(II):或其盐、溶剂合物、互变异构体、同分异构体或其混合物。
