Preprint on the permeability of Gram+ bacterial cell wall from a few months ago. Intriguing findings, elegant methodology. Cell wall is largely impermeable to molecule sizes of mNeonGreen (27kDa) and above. How do larger secreted proteins get through? www.biorxiv.org/content/10.1... #microsky

Looking for a deep dive into oxidoreductase distribution, structural plasticity & evolution across prokarya?

This new paper has you covered. 🐣

Big work just out from @pierresimongarcia.bsky.social , now a freshly minted PI.

Congratulations ! Looks amazing. 🦄

We analyzed the distribution of 31 HORBEC in over 4,000 bacterial and archaeal genomes. We propose a homogeneous nomenclature of HORBEC and their components and developed a tool, HORBEC-Finder, for automatic annotation from genomes(try it here! doi.org/10.6084/m9.f...).

Finally, we reconstructed the labyrinthic evolutionary history of HORBEC, from two ancient modules to the wide diversity that we observe in contemporary organisms.

Evolution and diversity of oxidoreductases involved in redox balance and energy conservation - Nature Ecology & Evolution HORBEC are protein complexes involved in the regulation of redox balance and energy conservation. The authors develop a bioinformatic tool for HORBEC annotation in bacterial and archaeal genomes and r...

This is excellent. But when will we be able to get it? The filter I mean. Someone will try to sell you a washing-machine fish, don't fall for it.

wonder what name you will come up for the "tiny arms" that are clearly not pili, not archaella, not pseudopodia either...
pseudobracchia ?

Rare microbial relict sheds light on an ancient eukaryotic supergroup - Nature The discovery of an unusual protist named Solarion arienae, which has a mitochondrial genome with some intriguing features, provides insight into the early radiation of eukaryotic groups.

Each such discovery is a game changer for our understanding of eukaryote evolution, and this paper is no exception. Meet Solarion, which displays yet again novel types of subcellular structures. Congrats to all authors on a fascinating story. #protistsonsky
