pyrrolamide metabolites produced by Streptomyces venezuelae ATCC 14583 and 14585. Isolated in 1965, they were reported to exhibit anthelmintic and moderate antibacterial activities. In this study, we revise the structure of anthelvencin A and identify a third anthelvencin metabolite, bearing two N-methylated pyrrole groups, which we named anthelvencin C. We sequenced the genome of S. venezuelae ATCC 14583 and
安特万星A和B是委内瑞斯链霉菌ATCC 14583和14585产生的吡咯酰胺代谢产物。1965年分离,据报道它们具有驱虫和中度抗菌活性。在这项研究中,我们修改了蒽铁霉素A的结构,并鉴定了带有两个N-甲基化吡咯基团的第三蒽铁代谢物,我们将其命名为蒽铁霉素C。我们对委内瑞拉链球菌ATCC 14583的基因组进行了测序,并鉴定了预计可指导直接遗传的基因簇花粉生物素的生物合成。该基因簇的功能分析证实了它参与了蒽醌的生物合成,并允许我们提出蒽醌的生物合成途径。除非核糖体肽合成酶(NRPS)外,蒽醌素的组装还涉及来自ATP抓握连接酶家族的一种酶Ant23。我们建议Ant23使用负载PCP的4-氨基吡咯-2-羧酸盐作为底物。如观察到其他吡咯酰胺酰胺刚果(由Streptomyces ambofaciens ATCC 25877生产)和双歧霉素(由Streptomyces netropsis DSM 408
