almost 20 years, is produced by all strains of Xenorhabdus nematophila. Despite its simple structure, its biosynthesis was unknown. Its biosynthetic pathway is reported using heterologous production in Escherichia coli. Additionally, the identification, structure elucidation, and biosynthesis of six extended nematophin derivatives from Xenorhabdus PB62.4 carrying an additional valine are reported. Preliminary
线虫素是一种抗金黄色葡萄球菌近20年的已知抗生素天然产物,它是由所有Xenorhabdus nematophila菌株产生的。尽管其结构简单,但其生物合成仍是未知的。据报道,其生物合成途径是利用大肠杆菌中的异源生产。此外,还报道了来自Xenorhabdus PB62.4的6种扩展的线虫素衍生物的鉴定,结构阐明和生物合成,这些衍生物带有附加的缬氨酸。初步的生物活性研究表明,这些化合物在细菌-线虫-昆虫共生中具有生物学作用。
