真菌(子囊菌门和担子菌门)是结构多样的萜类化合物的多产生产者。在真菌中发现的萜类化合物包括倍萜类、二萜类和三萜类。生物合成途径和酶从每一类萜类已被描述。这些通常包括产生萜烯合成酶和环化酶的支架,以及支架剪裁酶,例如细胞色素P450单加氧酶,NAD(P)+和黄素依赖的氧化还原酶,以及产生最终生物活性结构的各种基团转移酶。几种倍半萜类真菌毒素和生物活性二萜类的生物合成在子囊菌科(如丝状真菌)中得到了很好的研究。担子菌科(如蘑菇形成真菌)的萜类生物合成途径知之甚少,尽管它们产生大量的萜类天然产物。具体来说,许多反式葎草基阳离子衍生的倍半萜类天然产物已被分离出来,具有强大的生物活性。生物合成基因簇负责生产反式葎草基阳离子衍生的原illudanes和其他倍半萜,可以通过基因组测序和生物信息学方法快速鉴定。基因组挖掘与异源生物合成途径重构相结合,有可能促进药物相关真菌萜类化合物的发现和生产。
Fungi (Ascomycota and Basidiomycota) are prolific producers of structurally diverse terpenoid compounds. Classes of terpenoids identified in fungi include the sesqui-, di- and triterpenoids. Biosynthetic pathways and enzymes to terpenoids from each of these classes have been described. These typically involve the scaffold generating terpene synthases and cyclases, and scaffold tailoring enzymes such as e.g. cytochrome P450 monoxygenases, NAD(P)+ and flavin dependent oxidoreductases, and various group transferases that generate the final bioactive structures. The biosynthesis of several sesquiterpenoid mycotoxins and bioactive diterpenoids has been well-studied in Ascomycota (e.g. filamentous fungi). Little is known about the terpenoid biosynthetic pathways in Basidiomycota (e.g. mushroom forming fungi), although they produce a huge diversity of terpenoid natural products. Specifically, many trans-humulyl cation derived sesquiterpenoid natural products with potent bioactivities have been isolated. Biosynthetic gene clusters responsible for the production of trans-humulyl cation derived protoilludanes, and other sesquiterpenoids, can be rapidly identified by genome sequencing and bioinformatic methods. Genome mining combined with heterologous biosynthetic pathway refactoring has the potential to facilitate discovery and production of pharmaceutically relevant fungal terpenoids.
