The working dead 🧟‍♀️: not just a metaphor for PhD students but also an enzymatic strategy!

If you are curious how a pseudoenzyme (aka the “dead” version of an enzyme) produces indole in plants 🌱check out our preprint: www.biorxiv.org/content/10.1...

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...

(2/2) We discovered that core eudicot use TSB-like a catalytically dead version of the tryptophan synthase beta-subunit (TSB) to highjack and fool tryptophan synthase alpha-subunit (TSA) into efficiently producing indole instead of tryptophan!

(1/2) Indole is a very important compound for plants to defend themselves 🛡️, attract pollinators 🐝, communicate with other plants 🌱 and produce natural products 🧪.

However, how the majority of plants produce it was unknown.
