Genome sequencing has revealed that fungi have the ability to synthesize many more natural products (NPs) than are currently known, but methods for obtaining suitable expression of NPs have been inadequate. We have developed a successful strategy that bypasses normal regulatory mechanisms. By efficient gene targeting, we have replaced, en masse, the promoters of nonreducing polyketide synthase (NR-PKS) genes, key genes in NP biosynthetic pathways, and other genes necessary for NR-PKS product formation or release. This has allowed us to determine the products of eight NR-PKSs of Aspergillus nidulans, including seven novel compounds, as well as the NR-PKS genes required for the synthesis of the toxins alternariol (8) and cichorine (19). << Less

The genome sequencing of Aspergillus species including A. nidulans reveals that the products of many of the secondary metabolism pathways in these fungi have not been elucidated. Our examination of the 27 polyketide synthases (PKS) in A. nidulans revealed that one highly reduced PKS (HR-PKS, AN1034.3) and one nonreduced PKS (NR-PKS, AN1036.3) are located next to each other in the genome. Since no known A. nidulans secondary metabolites could be produced by two PKS enzymes, we hypothesized that this cryptic gene cluster produces an unknown natural product. Indeed after numerous attempts we found that the products from this cluster could not be detected under normal laboratory culture conditions in wild type strains. Closer examination of the gene cluster revealed a gene with high homology to a citrinin biosynthesis transcriptional activator (CtnR, 32% identity/47% similarity), a fungal transcription activator located next to the two PKSs. We replaced the promoter of the transcription activator with the inducible alcA promoter, which enabled the production of a novel polyketide that we have named asperfuranone. A series of gene deletions has allowed us to confirm that the two PKSs together with five additional genes comprise the asperfuranone biosynthetic pathway and leads us to propose a biosynthetic pathway for asperfuranone. Our results confirm and substantiate the potential to discover novel compounds even from a well-studied fungus by using a genomic mining approach. << Less
