A new 16-membered lactone named protylonolide was isolated from the culture of the blocked mutant of Streptomyces fradiae, KA-427. Protylonolide was converted to tylosin by both parent strain and several tylosin-non-producing mutants of KA-427. Protylonolide is an important biosynthetic intermediate of tylosin.
从弗拉迪亚链霉菌(Streptomyces fradiae)的阻滞突变体 KA-427 的培养物中分离出了一种新的 16 元内酯,名为丙烯龙内酯(protylonolide)。KA-427的母株和几种不产生泰乐菌素的突变体都能将丙烯酰内酯转化为泰乐菌素。Protylonolide 是泰乐菌素的重要生物合成中间体。
