Four gene products are required for the fungal synthesis of the indole-diterpene, paspaline.
Paspaline belongs to a large, structurally and functionally diverse group of indole-diterpenes synthesized by filamentous fungi. However, the identity of the gene products required for the biosynthesis of paspaline, a key intermediate for the synthesis of paxilline and other indole-diterpenes, is not known. Transfer of constructs containing different pax gene combinations into a paxilline negative deletion derivative of Penicillium paxilli demonstrated that just four proteins, PaxG, a geranylgeranyl diphosphate synthase, PaxM, a FAD-dependent monooxygenase, PaxB, a putative membrane protein, and PaxC, a prenyl transferase, are required for the biosynthesis of paspaline.
