Elio Schaechter was one of my heroes. His 1958 paper with Ole Maaløe and Niels Kjeldgaard (fondly known as “SMK”) is a North Star for so much work in my group. A wonderful scientist, great communicator, and a very kind person. May his memory be a blessing.

This first-author publication is my… first! Archaea kill bacteria by targeting their Achilles’ heel: peptidoglycan. Big shoutout to @ahocher.bsky.social‬, @valeriesoo.bsky.social‬, Pauline Misson, @tobiaswarnecke.bsky.social‬ and MRC LMS Proteomics. A thread 🔽 journals.plos.org/plosbiology/...

New cool work from French friends and colleagues: identification of Rho termination sites in B. subtilis! academic.oup.com/nar/article/... #SubtiWiki @narjournal.bsky.social @inrae-france.bsky.social

The B. subtilis histidine-containing phosphocarrier protein (HPr) supports PTS-sugar import, interacts with GAPDH, and helps mediate carbon catabolite repression (CCR). Here, a mutant HPr protein is shown to alleviate metabolic intoxication in a cpgA mutant. journals.asm.org/doi/10.1128/...

Metal ions are universally required for life, and many of the foundational principles of metal homeostasis have emerged from studies of microbial systems. In this review, I provide a introductory overview targeted to those new to the field. #MicroSky #Metals rdcu.be/eycU2

Bacterial sporulation (endospore formation) is complicated,but it turns out a lot of steps are regulated by classically defined developmental "checkpoints", and not events that are intrinsically required for the next step to occur. Zac Park reviews these in #Bacillus subtilis doi.org/10.1146/annu...

This took us a while and I am all the happier it is finally out! I thought that simply adding ATP to purified potassium channel KtrAB should be sufficient to stabilize its active state. I was so wrong... Read the full story on how an IDR facilitates channel opening upon membrane interaction.
