Tailoring steps are often important for the activity of mature antibiotics. Here, we report that novel decarboxylated FR-008/candicidin derivatives were obtained from the P450 monooxygenase gene fscP mutant of Streptomyces sp. strain FR-008. The toxicity of decarboxylated FR-008/candicidin derivatives has been shown to be greatly reduced compared to that of wild-type FR-008/candicidin.
剪裁步骤对成熟抗生素的活性通常很重要。在此,我们报道了从链霉菌属菌株FR-008的P450单加氧酶基因fscP突变体中获得了新型脱羧FR-008/杀假丝菌素衍生物。与野生型FR-008/杀假丝菌素相比,脱羧FR-008/杀假丝菌素衍生物的毒性已被证明大大降低。
