I've just released a small open-source utility for RELION users: relion_tracker. RELION stores a lot of useful information in the *_optimiser.star files, but I often found myself repeatedly grepping STAR files to see how metrics were changing across iterations.

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

OUT NOW: KorB is a DNA clamp which slides along DNA to mediate long-range gene silencing upon interaction with the clamp-locking KorA protein by Tung Le & co @johninnescentre.bsky.social www.nature.com/articles/s41...

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...
