Diderm Firmicutes strike again! "The Mla system of diderm Firmicute Veillonella parvula reveals an ancestral transenvelope bridge for phospholipid trafficking" Another beautiful story on the bacterial envelope with @chrisbel70.bsky.social@jmghigolab.bsky.socialrdcu.be/drNQ3#MicroSky
Merci Christoph!
Structuring effects of archaeal replication origins www.biorxiv.org/content/10.1101/2023.11.15.567178v1
Archaea use eukaryotic-like DNA replication proteins to duplicate circular chromosomes similar to th
Iron-Sulfur clusters are essential protein co-factors in eukaryotes and are synthesized in mitochondria and plastids by ISC and SUF systems. Can we use these machineries to investigate the origins of organelles? Happy to share our short report out today! #MicroSkyjournals.plos.org/plosbiology/...
The symbioses that gave rise to primary organelles are key events in the origin of Eukaryotes. This study uses a dataset of markers belonging to two conserved machineries responsible for [Fe-S] cluste...
Our paper on structural and functional characterisation of OmpM, the predominant outer membrane tethering system in Terrabacteria, is now out! Great collaboration between @sgribaldo.bsky.social@sykhalid.bsky.socialwww.nature.com/articles/s41...
Outer membrane tethering is important for cell envelope integrity in diderm bacteria. Here, the authors present structures and functional analyses of the stalked porin OmpM, which is the main outer me...

Amazing TEM... Proposed lifecycle: "A MJ1T cell is divided on the cell surface of its host. The daughter cell (ii) leaves the host or (iii) swims with the host, attaches to a new host cell, and (iv) sucks the cytosol from the host."

🦠 🧫 Halloween preprint 🎃 from our lab! Live-cell + cryoEM imaging of the lifecycle of B. exovorus, a predatory bacterium that feeds on Caulobacter (+ close relatives) while firmly attached to the prey surface. The S-layer does not protect against vampirization… and B.exovorus divides into triplets 😮
Lifecycle of a predatory bacterium vampirizing its prey through the cell envelope and S-layer https://www.biorxiv.org/content/10.1101/2023.10.25.563945v1
Predatory bacteria feed upon and kill other bacteria in various natural environments. Obligate epibi
