An unconventional Rubisco small subunit underpins the CO2-concentrating organelle in land plants In many algae, photosynthesis is boosted by biophysical CO2-concentrating mechanisms, which pack the CO2-fixing enzyme Rubisco into liquid-like organelles called pyrenoids. Engineering C3 crops with a...

Our work on #hornwort #pyrenoids is finally out in @science.org! 🎉 We uncovered how hornworts pack their Rubisco into pyrenoids and successfully recreated them in Arabidopsis. A key step toward engineering more efficient photosynthesis in crops @btiscience.bsky.social www.science.org/doi/10.1126/...

Cool Preprint led by @mirbachh on comparing machine learning based engineering of a synthetic C1 fixation pathway vs the classic ALE based approach. ML allowed way faster pathway establishment and when combined with the evolved background improved growth by a factor of 3.🔥🎉

When evolution and enzyme engineering team up, they can convince microbes to assimilate sustainable carbon substrates preparing them for a life in a circular bioeconomy.

doi.org/10.1016/j.ym...

A blueprint for designing the next-generation of synthetic C1 microbes - Nature Communications Synthetic one-carbon assimilation could contribute to a more sustainable and circular carbon economy, but much work in this field has focused on model microorganisms. Here the authors provide their perspective on the potential value of non-model microbes, and how that potential could be realised.

🚀 Thrilled to share our new Nature Communications article:
“A blueprint for designing the next-generation of synthetic C1 microbes”
We propose a framework to unlock sustainable, carbon-efficient biomanufacturing using non-canonical hosts.

Really impressive work from Ari and the team - going from an idea all the way to a functional pathway using the latest synbio tools! The CORE cycle is another carbon fixing route that could be used as an alternative to photorespiration in plants. Interested to see where this goes next! 🌱📈

Groundbreaking work just dropped🔥.
@ari-satanowski.bsky.social and Daniel Marchal engineered new-to-nature CO2 reduction at ambient conditions via ATP-driven cycles for CO2->formate in vivo.
All kinds of fancy experiments in here and a real seminal contribution to the field👏. Check it out!
