We’re excited to share our latest study that reshapes our understanding of Mycobacterium tuberculosis (Mtb) lipid composition, with major implications for drug discovery, immunity, and vaccine development. www.nature.com/articles/s41... A thread.

We have an opening for a research support officer. Come and join us! Please share.

Our latest paper on the molecular mechanisms of XPF-ERCC1 recruitment to SLX4-dependent DNA repair pathways has been published! Congratulations to first author Junjie Feng, and a heartfelt thank you to all our collaborators for their contributions to this study! www.nature.com/articles/s41...

Vaults. They are cell biology's greatest puzzle! This preprint from Martin Beck's lab shows them docked on ER membranes with a ribosome inside. What on earth is going on there?? #CellBiology #WTFology www.biorxiv.org/content/10.6...

I’m excited to announce that I will be starting my research group on computational enzyme design at the Generative Biology Institute, Oxford, UK (@eitoxford.bsky.social)! PhD applications are open, deadline is Jan 8th (www.chem.ox.ac.uk/genbio-dtp). Email [email protected] with any questions!

New paper! We’ve found that Bacteroides thetaiotaomicron deploys extracellular vesicles to scavenge and deliver vitamin B12, driven by a newly identified high-affinity binding protein, BtuJ. The system functions analogously to microbial siderophores. #microbiology #microbiome #extracellularvesicles

Mycobacterium tuberculosis is an outlier in many ways. One of them is keeping a high degree of functional redundancy despite its obligate pathogen lifestyle. In this review, we reflect on the biological meaning of M. tuberculosis functional redundancies. journals.plos.org/plospathogen...

Please RT. Post-doc opportunity alert! 💥 closing soon 10th December.. Come join our team (www.thelowlab.org) at Imperial, London, working on the structure and mechanism of bacterial secretion systems. For more details and to apply please see www.imperial.ac.uk/jobs/search-...

If you or someone you know is looking for a post-doctoral position working on mycobacterial envelope biology, please get in touch. I am recruiting here at the University of Western Ontario in London, Ontario, Canada.

This has now been published in print! Check it out: www.science.org/doi/10.1126/...

Exciting collab with Paul Palme, Peter Imming, & Adrian Richter! Guided by @courbongautier.bsky.social's structure of myco ATP synthase bound to a squaramide, they have made SQAs that are less toxic, more potent, more stable than AstraZeneca's SQ31f #MedChem #TB #NTM pubs.acs.org/doi/full/10....

Proteins are dynamic structures, but structural biology often shows them as static snapshots. Inspired by long-exposure photography and generative art, I built ProteinCHAOS, an artistic tool inspired by molecular dynamics to capture protein flexibility over time, much like long-exposure images.

🚀 Hiring: Cryo-EM Application Scientist, Marketing! Develop and deliver high-impact scientific marketing content, illustrate the value of new #CryoSPARC features and #cryoEM advances, and help scientists understand how our tools can help solve their problems. structura.bio/careers/appl...

Why would Mycobacterium shed its surface right after entering a host cell? Host phagocytes rapidly strip its outer layer, releasing components that alert neighbors and trigger defense responses Our preprint is out, curious to hear your take! 👀 www.biorxiv.org/content/10.1...

Thrilled to share our work on the 🔥 single-celled predator Podophrya collini, which rewires its cell morphology to hunt more efficiently. Huge thanks to our amazing team—Amy, Lauren, Omaya, Marine, Mari, and especially Scott—for making this shine! ✨

#NewResearch A bile acid-bound structure of toxin TcdB revealed the mechanism of inhibition and guided the design of a synthetic bile acid that alleviated C. difficile infection in mice. #MicroSky 🦠💊 www.nature.com/articles/s41...

Great work, beautiful structures and really interesting new insights into #Cdiff toxin inhibition. Congratulations to all! #microsky

With the Wilmanns lab @embl.org we reveal cryoEM structures of an essential, bifunctional acyl-CoA carboxylase from mycobacteria. @wertheimufscripps.bsky.social This ~ 600 kDa enzyme is asymmetric, rotatory, has unusual stoichiometry, and unique E5 subunits. www.biorxiv.org/content/10.1...

How does the well tolerated anti-hyperglycemic drug #metformin inhibit mitochondrial complex I? In our new paper, we use structures, MD and kinetics to show that metformin inhibits by a distinct mechanism that more hydrophobic, less well tolerated, biguanides. www.nature.com/articles/s41...

MISO: microfluidic protein isolation enables single-particle cryo-EM structure determination from a single cell colony. Or from a single dish of HEK cell culture in the case of two membrane proteins. Out in Nature Methods now! lnkd.in/gpyBSceg Wonderful collaboration with the Efremov lab.

The Center for Microscopy and Image Analysis at the University of Zurich is seeking a new Head: jobs.uzh.ch/job-vacancie... It is super fun to work with them, tons of expertise and cutting edge instrumentation in ❄️🔬 Application deadline: December 15, 2025.

New paper alert! Scientists in Clemens Plaschka’s lab at the IMP and @juliusbrennecke.bsky.social's lab at @imbavienna.bsky.social solved a decade-old puzzle, uncovering how the information molecule mRNA travels from the cell’s nucleus to its periphery. More: bit.ly/4nHcvys

Great collaboration with @guo-lab.bsky.social to determine an in situ architectural model of the Tad pilus machine. Be on the lookout soon for a preprint on the same topic by Grant Jensen and @viollierpat.bsky.social. #microsky

Excited to share our latest @nature.com: How does naloxone (Narcan) stop an opioid overdose? We determined the first GDP-bound μ-opioid receptor–G protein structures and found naloxone traps a novel "latent” state, preventing GDP release and G protein activation.💊🧪 🧵👇 www.nature.com/articles/s41...

M. smegmatis uses new types of biofilm to enclose a liquid core and expand outwards in a weird new way.

Our new preprint is out 🥳🥳🥳 Henipaviruses, like Nipah and Hendra, package their genomes inside helical shells built by thousands of nucleoproteins. These nucleocapsids are essential to protect the viral RNA, but how do they ever let the polymerase in to read the sequence? 👇

🥳 Today marks the start of the lab of former postdoc @florianwollweber.bsky.social at @embl.org Grenoble! www.embl.org/groups/wollw... Florian-- we will miss you dearly and wish you much success! With us, Florian applied multiscale imaging 🔬to Asgard archaea ...👇

Interestingly, Yingke found some complexes bound to uncharacterized proteins MSMEG_0435 & 0436 (Rv0263c & 0264c in M. tuberculosis). A recent preprint from Carl Nathan shows that Rv0263c is needed for Mtb survival during transmission, suggesting it modulates mycolic acid synthesis in TB transmission

New lab preprint! @zestytoast.bsky.social tagged a scarce mycobacterial protein in M. smegmatis with TwinStep but got… something? @kjamali.bsky.social's ModelAngelo built models & @martinsteinegger.bsky.social's FoldSeek IDed them as the biotin-containing MCC & LCC complexes 🧵 tinyurl.com/ukny4ptz

Lab’s first paper is out!! We show the first structures of #Asgard #chromatin by #cryo-EM 🧬❄️ Asgard histones form closed and open hypernucleosomes. Closed are conserved across #Archaea, while open resemble eukaryotic H3–H4 octasomes and are Asgard-specific. More here: www.cell.com/molecular-ce...

Now out in Science! Cyclin-dependent kinases (CDKs) are key regulators of the cell cycle. In @vcushing.bsky.social's magnum opus, we use #cryoEM to figure out how the CDK-activating kinase recognises CDKs to fully activate them - a key step in cell cycle control. www.science.org/doi/10.1126/...

Have you ever looked at the night sky and wondered if there’s a chlorophyll f in the reaction centre of Photosystem I from far-red light adapted cyanobacteria? 🦠 Well, we did (don’t judge) and the work that followed is now out as a First Release in @science.org www.science.org/doi/10.1126/...

This is a perfect farewell to the @mpi-dortmund.bsky.social and the @raunser-lab.bsky.social. Big thanks to the whole team 😁. Interested in doing equally exciting work? I have open positions available soon in my newly established lab at the @nkinl.bsky.social in Amsterdam.

Very excited that my final postdoctoral work is now online in Cell @cellpress.bsky.social. www.sciencedirect.com/science/arti... Using 16 (!) cryo-EM structures, we uncovered how the three proteins coronin, cofilin and AIP1 work together to rapidly disassemble actin filaments.
