Good to see that my home country, the Netherlands, is still doing quite well! www.nature.com/articles/d41...
This is great! Conjugation without pili was always an annoying paradox, and this finding shows that things finally make sense.

Is there a good #contaminant checklist? Just had to tell a researcher that the sample they have been working on and I ran over the SEC-MALS for them, probably is the infamous ArnA his-tag purification contaminant from E. coli (100% Mw and ext. coeff. match). journals.iucr.org/d/issues/202...

Cryo-EM reveals ArnA contamination during purification of a ciliary protein complex
ArnA contamination was independently observed during the purification of a soluble, low-yield protein complex, leading to an unintended 3.23 Å resolution cryo-EM structure. This work broadens recent f...

📣New preprint with @rberntsson.bsky.social👇We overturn the long-standing view that Gram-positive bacteria lack conjugative pili! We identify pili-forming proteins in a wide range of bacteria and show they're essential for the spread of #antibioticresistance #AMR 🧵1/6 www.biorxiv.org/content/10.6...

Type IV secretion systems (T4SS) enable the spread of antibiotic resistance and other virulence factors. In Gram-positive bacteria, T4SSs have long been thought to lack VirB2-like proteins that form c...

Pili are essential for conjugation also in many Gram-positive bacteria
