New pre-print from the group 🥳 We use targeted genome mining to show that the plant pathogen Rhodococcus fascians makes the antibiotic lydiamycin. The BGC information then informed the discovery of multiple key features relating to the molecule 1/4

Our Taxol pathway preprint!
We developed a systematic strategy to activate and identify gene sets in plants. Used it to identify 8 genes in the Taxol pathway, enabling a 20-gene biosynthesis of a Taxol precursor.
Biggest surprise: a new protein that helps our oxidases produce the correct product
Multiplexed perturbation of yew reveals cryptic proteins that enable a total biosynthesis of baccatin III and Taxol precursors
Plants make complex and potent therapeutic molecules, but difficulties in sourcing from natural producers or chemical synthesis can challenge their use in the clinic. A prominent example is the anti-c...
