BIGDNATM Tools for Manipulating BGCs
Natural product biosynthesis is encoded in large, complex regions of DNA known as Biosynthetic Gene Clusters (BGCs). We have overcome the historical challenges of manipulating large contiguous BGCs to seamlessly integrate natural product development with modern approaches in synthetic biology.
- Our DNAtrapTM captures intact BGCs up to 150kb, irrespective of GC content or repetitive sequences
- Effectively captures BGCs from complex genomic DNA (gDNA) or metagenomic library substrates
- De-Risked: DNAtrapTM has been used to clone >130 intact BGCs
Engineering Expression of BGCs
In both native and heterologous microbial hosts natural product production is an innately regulated process, oftentimes limiting detection, analysis, and optimization of these valuable molecules. Our team has pioneered novel methodologies to predictably activate BGCs for both natural product screening and titer optimization workflows.
- Our patented BGCexpressTM inducible expression technology enables broad control over transcriptional activation and titer
- Induction increases natural product titers at least 2-3x facilitating functional bioactivity screening
- BGCrefactorTM in vitro tool for quick and precise refactoring of BGCs
- Multiplexed, marker-free refactoring workflow for
optimizing entire natural product biosynthesis
- Multiplexed, marker-free refactoring workflow for
Metabologenomics for Natural Product BGC Identification
Identifying putative BGCs in digital databases is routine, and so is broadly detecting natural products from microbial extracts. One of the major challenges that limits scaling discovery and optimization of these valuable molecules has been linking BGCs to their respective natural products.
To overcome this, we have developed patented bioinformatics and machine learning tools that link microbial metabolites with their biosynthetic pathways.
- Prospect Fungi is a proprietary analysis tool for in silico prediction and annotation of fungal BGCs
- An AI platform that grows and learns from known BGC:Natural Product relationships
- HAYSTACK-MS: Finding new drugs via targeted cloning
- Solves needle-in-the-haystack problem of finding target compounds in complex metabolite mixtures
- Rapidly identifies and produces natural products by heterologous expression
Hosts for Heterologous Expression
When it comes to optimal heterologous expression of natural products, host selection matters. Precursor metabolites, cofactors, among other host-specific variables can greatly influence the successful production of specific molecules. Our access to a suite of optimal heterologous hosts provides the greatest opportunity for natural product expression.
- CleanChassisTM strains have been engineered to reduce competing metabolite production
- Streptomyces, Bacillus, Aspergillus, and Gram Negative bacteria
- For every BGC of interest, our growing portfolio of CleanChassisTM strains represents an opportunity to accelerate optimal expression
