Quinone-transporting filaments extend the respiratory chain of Gram positive bacteria www.biorxiv.org/content/10.64898/2026.06.26.734721v1 #cryoem

This Visual-omics approach is kind of amazing: "We resolved each to sufficient resolution (2.8 and 3.6 Å) to predict the amino acid composition directly from the 3D electrostatic potential map"

Excited to be presenting this work today at the 3DEM Gordon Research Seminar and later this week at the Gordon Research Conference. Looking forward to the discussions and feedback! www.grc.org/three-dimens...

New paper alert!! We just discovered a new filament system that is widespread exclusively within CPR bacteria! www.biorxiv.org/content/10.6.... Short thread below. 🦠🔬🚀

Join #EMBOCryoEM to get a comprehensive foundation in advanced single-particle and cellular tomography techniques – we'll cover the entire workflow from sample preparation to data collection and image processing. https://s.embl.org/cry26-01-bl Apply by: 11 May 2026 @embo.org

My first manuscript in MPI colours! With @tothpetroczylab.bsky.social, we show that AlphaFold PAE-derived contact probabilities are well calibrated to the fraction of true interface contacts across experimentally determined protein dimers. www.biorxiv.org/content/10.6...

I am very grateful to @lorneproteins.bsky.social for the opportunity to speak and share my work! Such a great atmosphere, thank you for the warm welcome and excellent questions.

🌀 We solved the structure for T. denticola periplasmic flagella! I'm very happy to finally showcase this work. A huge collaborative effort between myself, @bindusmitapaul.bsky.social, @debnathghosal.bsky.social, Jack Kim, @banfieldlab.bsky.social, Eric Reynolds and the Chris Fenno lab. 🦠 Enjoy!

It has been great to be part of this team, thank you to everyone involved!

Wonderful spirochete asymmetric flagellar structural work by @lucatroman.bsky.social Grateful to be part of the story supported by @debnathghosal.bsky.social

📣 New paper alert! This is a story of molecular tricks that let spirochetes (spiral-shaped bacteria) drill through tissue. www.biorxiv.org/content/10.6...

🌀 How do spirochete bacteria swim through thick fluids like champions? We solved T. denticola flagella structure - asymmetric proteins expand one side, compress the other for perfect corkscrew motion! @debnathghosal.bsky.social 🔗 doi.org/10.64898/202... #StructuralBiology #CryoEM #Microbiology
