Monobactam formation in sulfazecin by a nonribosomal peptide synthetase thioesterase

Monobactam formation in sulfazecin by a nonribosomal peptide synthetase thioesterase, Published online: 20 November 2017; doi:10.1038/nchembio.2526

Biosynthesis of the antibiotic sulfazecin involves N-sulfonation in trans of the tripeptide intermediate before synthesis of the β-lactam ring by a noncanonical thioesterase domain, demonstrating a new enzymatic route to the azetidinone moiety.

非核糖体肽合成酶硫酯酶在磺胺嘧啶中形成单细菌素

非核糖体肽合成酶硫酯酶在磺胺嘧啶中形成单细菌素,在线发布:2017年11月20日; doi:10.1038 / nchembio.2526

抗生素磺胺嘧啶的生物合成涉及三肽中间体的反式N磺化,然后再通过非规范的硫酯酶结构域合成β-内酰胺环,这表明了通往氮杂环丁酮部分的新酶促途径。
