Triterpenes with complex scaffold modifications are widespread in the plant kingdom. Limonoids are an exemplary family that are responsible for the bitter taste in citrus (e.g., limonin) and the active constituents of neem oil, a widely used bioinsecticide (e.g., azadirachtin). Despite the commercial value of limonoids, a complete biosynthetic route has not been described. Here, we report the discovery of 22 enzymes, including a pair of neofunctionalized sterol isomerases, that catalyze 12 unique reactions in the total biosynthesis of kihadalactone A and azadiraone, products that bear the signature limonoid furan. These results enable access to valuable limonoids and provide a template for discovery and reconstitution of triterpene biosynthetic pathways in plants that require multiple skeletal rearrangements and oxidations. Discovery of 22 enzymes responsible for the production of bioactive limonoids with complex scaffold rearrangements from Citrus and Meliaceae species.
