羊毛甾醇14α-脱甲基酶(CYP 51)是抗真菌药物开发的重要靶点。真菌衍生的限制性内切酶1和相关分子是抑制CYP 51的天然产物的唯一实例。在这里,使用编码自身抗性CYP 51的基因的共定位作为查询,我们确定并验证了1的生物合成基因簇(BGC)。对具有CYP 51的相关BGC的额外基因组挖掘导致产生相关羊毛霉素2。从未知产生这些化合物的真菌中鉴定了1和2的途径,突出了自抗性酶(SRE)指导的生物活性天然产物发现方法的前景。
Lanosterol 14α-demethylase (CYP51) is an important target in development of antifungal drugs. The fungal-derived restricticin 1 and related molecules are the only examples of natural products that inhibit CYP51. Here, using colocalizations of genes encoding self-resistant CYP51 as query, we identified and validated the biosynthetic gene cluster (BGC) of 1. Additional genome mining of related BGCs with CYP51 led to production of the related lanomycin 2. The pathways for both 1 and 2 were identified from fungi not known to produce these compounds, highlighting the promise of self-resistance enzyme (SRE) guided approach to bioactive natural product discovery.
