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/...

Register: March 26 Webinar on the New PDB Beta Archive
Learn how to become an early adopter of the future PDB
The new directory structure is organized around extended PDB IDs and will replace the current archive when all 4-character PDB IDs are assigned

The image shows DNA nucleosomes arranged from histones in archaea. DNA is portrayed as an incandescent metal in a heated environment.

February's PDB Molecule of the Month is for "Histones Across the Tree of Life".

I wanted to focus on the histones of archaea Methanothermus fervidus which thrives at 83°C in sulfur pools in Iceland.

I call the image: "Compacting DNA at nearly boiling water."

Congrats Jens! 🎉🎉

Long in the making, but happy to present the Chlamydomonas chlororibosome!
Cryo-ET🔬reveals a large new domain on the small subunit, built from multiple extensions in conserved ribosomal proteins.
