Bacillus subtilis biofilm formation is strongly stimulated by manganese. New results from Sachla et al. show that a Mn export protein (MeeY) and YybP are important for biofilm regulation, maturation, and proper matrix metalation 🎉🧪🦠 #Microsky www.nature.com/articles/s41...

So happy to see this paper finally out 🥳 it took only seven years after the first purification of archaeal peptidoglycan 🤣 Congrats to all the people involved 🥂🍾 And here is the story behind the paper: communities.springernature.com/posts/cracki...

Interested in #archaea, #methane, #cell-envelopes? New paper out @nature.com ! We discovered an enzyme that specifically cleaves the cell wall of methanogens, revealing a new chemical structure of archaeal peptidoglycan, 50 yrs after its first description www.nature.com/articles/s41... #MicroSky 🧵👇

Heading home after a great EMBO TB meeting in Paris. Always such an exciting meeting giving a great overview of what is happening in the field @hrryflwr.bsky.social did a great job presenting his poster as well :D #embocomplexinfections @embo.org @lkremer1.bsky.social @figlegend.bsky.social

How do proteins localize in bacteria? Usually by binding to a prelocalized protein-but how does that protein localize? @vanipande.bsky.social found a #Bacillus subtilis protein that localizes via a lipid cue,undecaprenyl phosphate,that guides it to sites of PG synthesis www.pnas.org/doi/10.1073/...
