New tools for reconstruction and heterologous expression of natural product biosynthetic gene clusters.
Natural product scaffolds remain a major source and inspiration for human therapeutics. However, generation of a natural product in the post-genomic era often requires reconstruction of the corresponding biosynthetic gene cluster in a heterologous host. In the burgeoning fields of synthetic biology and metabolic engineering, a significant amount of efforts has been devoted to develop DNA assemb...
متن کاملMultiplexed CRISPR/Cas9- and TAR-Mediated Promoter Engineering of Natural Product Biosynthetic Gene Clusters in Yeast.
The use of DNA sequencing to guide the discovery of natural products has emerged as a new paradigm for revealing chemistries encoded in bacterial genomes. A major obstacle to implementing this approach to natural product discovery is the transcriptional silence of biosynthetic gene clusters under laboratory growth conditions. Here we describe an improved yeast-based promoter engineering platfor...
متن کاملYeast homologous recombination-based promoter engineering for the activation of silent natural product biosynthetic gene clusters.
Large-scale sequencing of prokaryotic (meta)genomic DNA suggests that most bacterial natural product gene clusters are not expressed under common laboratory culture conditions. Silent gene clusters represent a promising resource for natural product discovery and the development of a new generation of therapeutics. Unfortunately, the characterization of molecules encoded by these clusters is ham...
متن کاملDiverse and Abundant Secondary Metabolism Biosynthetic Gene Clusters in the Genomes of Marine Sponge Derived Streptomyces spp. Isolates
The genus Streptomyces produces secondary metabolic compounds that are rich in biological activity. Many of these compounds are genetically encoded by large secondary metabolism biosynthetic gene clusters (smBGCs) such as polyketide synthases (PKS) and non-ribosomal peptide synthetases (NRPS) which are modular and can be highly repetitive. Due to the repeats, these gene clusters can be difficul...
متن کاملNatural product biosynthetic gene diversity in geographically distinct soil microbiomes.
The number of bacterial species estimated to exist on Earth has increased dramatically in recent years. This newly recognized species diversity has raised the possibility that bacterial natural product biosynthetic diversity has also been significantly underestimated by previous culture-based studies. Here, we compare 454-pyrosequenced nonribosomal peptide adenylation domain, type I polyketide ...
