Would you expect that Bacteria use an archaellum for swimming? We didn't, but we found that some Chloroflexota do! Find the story here: www.biorxiv.org/content/10.1...

A little thread below 1/n
Horizontal gene transfer of the functional archaellum machinery to Bacteria
Motility in Archaea is driven by a nanomachinery called the archaellum. So far, archaella have been exclusively described for the archaeal domain; however, a recent study reported the presence of arch...

New preprint 🚨: with @madejmar.bsky.social we found that the Bacteroidetes beta-barrel assembly machinery is quite different to E. coli. www.biorxiv.org/content/10.1... #cryo-EM
Comparison of B. theta and E. coli BAM machineries. Only BamAD components are shared, and B. theta BAM has five novel components, BamF-I.

KorB switching from DNA-sliding clamp to repressor mediates long-range gene silencing in a multi-drug resistance plasmid - Nature Microbiology
Structural and single-molecule analyses show the CTPase, KorB, is a sliding DNA clamp that interacts with a clamp-locking protein KorA to inhibit gene expression over distances of more than 1 kb in th...
