The manuscript introducing ArchaeaHQ is still under review😴 As science can't wait... I'm making available a version of the dashboard we use. vee-lab.eu/archaeahq Here the user can have quick access to the information in the database, and select specific genomes of interest. Enjoy 🎉

I'm happy to share the first pre-print of out Lab! 🎉 Introducing ArchaeaHQ www.biorxiv.org/content/10.6... We curated 21,644 genomes across all 4 archaeal kingdoms to bridge the gap in public datasets for computational biology What is inside ArchaeaHQ... (1/2)

Some bacteria do not live as individuals. They build multicellular filaments and connect neighboring cells through tiny cell-cell junctions. Cyanobacteria are among the most beautiful examples 😍 In our new paper, we reveal first molecuar insights on the cyanobacterial septal junction architecture 🧵

🚨 New in @natmicrobiol.nature.com! We reveal how the antibiotic target PBP1b fortifies the E.coli division site against osmotic rupture. Proud this was completed in our independent labs @dmf-unil.bsky.social, with @avettiger.bsky.social. Congratulations to all authors! 🦠❄️🔬 #teamtomo bit.ly/3SCbOg1 👇

The penicillin-binding protein PBP1b fortifies the Escherichia coli division site against osmotic rupture - Nature Microbiology

A specific isoform of PBP1b functions independently of the activator protein, LpoB, to drive generation of a wedge-like peptidoglycan structure that strengthens the division site in Escherichia coli.

My first story about Archaea cell division comes out !!! A three protein system (Dip system) positions H. volcanii divisome to midcell. Dip system works like bacterial Min sytem, but they share NO sequence homology "All roads lead to Rome😊".

Sonja-Verena Albers@archaellum.bsky.social · 3mo ago

New preprint! Cell division has to happen at the right place but how Archaea pick that place is unknown. We now identified a three-protein system, Dip, that positions the divisome at midcell in H. volcanii and is broadly conserved across Archaea. A thread 🧵 www.biorxiv.org/content/10.6...

How do archaea find mid cell? They invent their own new system! Check out the preprint and admire those beautiful fluorescence images of @weiwaer.bsky.social Happy to have been part of it🎉

How do “LEGO-like” electron-bifurcating modules combine to drive degradation in BTEX-contaminated ecosystems? Check out our latest preprint, where we use cryo-EM and cryo-ET to reveal how the 1 MDa BCRII complex powers extremely endergonic aromatic ring reduction. www.biorxiv.org/content/10.6...

One of biggest mysteries in biology: how did complex eukaryotic cells evolve from simple microbes? ~1.8 billion years ago, an archaeal cell likely merged with a bacterium to form the first eukaryotic cell, but can we ever find direct evidence of this transformative event? 🦠 🚶‍♂️
