麦角生物碱是一类由真菌衍生的具有重要生物活性的天然产物,它是由一种常见的中间体——麦角碱- 1精制而成的一组不同的结构。在此,我们报道了环丙基麦角生物碱的生物合成途径的发现,环丙基是一种复杂的麦角生物碱。我们使用基于酵母的表达平台以及体外生化实验来鉴定催化chanoclavine- 1中间体重排形成环丙基片段的酶。所得化合物cycloclavine在酵母中以> - 500 mg L−1的滴度产生,从而证明了这些复杂生物碱的异种表达的可行性。
The ergot alkaloids, a class of fungal-derived natural products with important biological activities, are derived from a common intermediate, chanoclavine-I, which is elaborated into a set of diverse structures. Herein we report the discovery of the biosynthetic pathway of cycloclavine, a complex ergot alkaloid containing a cyclopropyl moiety. We used a yeast-based expression platform along with in vitro biochemical experiments to identify the enzyme that catalyzes a rearrangement of the chanoclavine-I intermediate to form a cyclopropyl moiety. The resulting compound, cycloclavine, was produced in yeast at titers of >500 mg L−1, thus demonstrating the feasibility of the heterologous expression of these complex alkaloids.
