evolution protocols for nonribosomalpeptidesynthetases are needed to adapt the structures of antibiotic peptides for the fight against antimicrobial resistance. Here, an easily reproducible directed evolution protocol was used to reprogram the synthetase for the antibiotic peptide gramicidin S. A few mutations were sufficient to incorporate the non-standard building block piperazic acid instead of proline
需要针对非核糖体肽合成酶的有效定向进化方案来调整抗生素肽的结构以对抗抗菌素耐药性。在这里,使用一种易于重复的定向进化方案来重新编程抗生素肽短杆菌肽 S 的合成酶。一些突变足以以完美的特异性掺入非标准构件哌嗪酸而不是脯氨酸。
