Abstract

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.
