担子菌门的次级代谢组代表了药学相关天然产物的一个很大程度上未表征的来源。萜类化合物是从蘑菇中分离出的主要一类生物活性化合物。Jack O'Lantern蘑菇Omptus olearius在50年前被鉴定为抗癌伊鲁啶倍半萜类化合物的多产者,然而迄今为止,对这些重要化合物的生物合成的研究非常少。在这里,我们报告的基因组序列草图O。olearius,揭示了一个多样的倍半萜烯糖苷酶网络和两个与伊鲁定生物合成相关的代谢基因簇。他们的生化特性,使所有目前可用的担子菌基因组的全面调查,从而创造了一个预测资源萜类天然产物的生物合成在这些生物体。我们的研究结果将有助于发现和生物合成生产独特的药物相关的生物活性化合物从担子菌。
The secondary metabolome of Basidiomycota represents a largely uncharacterized source of pharmaceutically relevant natural products. Terpenoids are the primary class of bioactive compounds isolated from mushrooms. The Jack O’Lantern mushroom Omphalotus olearius was identified 50 years ago as a prolific producer of anticancer illudin sesquiterpenoids, however to date there have been exceptionally few studies into the biosynthesis of these important compounds. Here we report the draft genome sequence of O. olearius, which reveals a diverse network of sesquiterpene synthases and two metabolic gene clusters associated with illudin biosynthesis. Their biochemical characterization enabled a comprehensive survey of all currently available Basidiomycota genomes, thereby creating a predictive resource for terpenoid natural product biosynthesis in these organisms. Our results will facilitate discovery and biosynthetic production of unique pharmaceutically relevant bioactive compounds from Basidiomycota.
