Hirsutellones are fungal natural products containing a macrocyclic cyclophane connected to a decahydrofluorene ring system. We have elucidated the biosynthetic pathway for pyrrocidine B () and GKK1032 A (). Two small hypothetical proteins, an oxidoreductase and a lipocalin-like protein, function cooperatively in the oxidative cyclization of the cyclophane, while an additional hypothetical protein in the pyrrocidine pathway catalyzes the specific cycloaddition to form the fused decahydrofluorene.
希鲁特酮类化合物是一类含有大环环丙烷连接到十氢芴环系统的真菌天然产物。我们阐明了吡咯西啶 B () 和 GKK1032 A () 的生物合成途径。两个小的假设蛋白,一种氧化还原酶和一种类脂蛋白,在环丙烷的氧化环化中协同作用,而吡咯西啶途径中的另一个假设蛋白则催化特定的环加成反应,形成融合的十氢芴。
