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 کاملHeterologous expression of novobiocin and clorobiocin biosynthetic gene clusters.
A method was developed for the heterologous expression of biosynthetic gene clusters in different Streptomyces strains and for the modification of these clusters by single or multiple gene replacements or gene deletions with unprecedented speed and versatility. Lambda-Red-mediated homologous recombination was used for genetic modification of the gene clusters, and the attachment site and integr...
متن کاملCloning and Heterologous Expression of a Large-sized Natural Product Biosynthetic Gene Cluster in Streptomyces Species
Actinomycetes family including Streptomyces species have been a major source for the discovery of novel natural products (NPs) in the last several decades thanks to their structural novelty, diversity and complexity. Moreover, recent genome mining approach has provided an attractive tool to screen potentially valuable NP biosynthetic gene clusters (BGCs) present in the actinomycetes genomes. Si...
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 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...
