Here is our recent work on T7SSb LXG effectors and the proteins that are required for their secretion. Thank you to everyone that contributed to the work and to @mbiojournal for the valuable reviews and speedy publication. journals.asm.org/doi/10.1128/mb…
So excited to finally share these results of my 7 years effort. Thanks the whole @MarlovitsLab team for great support and esp. @DirkFahrenkamp, @nikigoessi! This was a wild ride... starting with a simple question. How does the complex move the DNA - lever is the answer. SOUND ON!
Resolving the AAA+ ATPase Puzzle in Slow Motion. Cutting-edge cryoEM, time-resolved studies and slower burning fuels. Big thanks to the heroes of the M-team; esp. @JirkaWald @DirkFahrenkamp. Enjoy! (marlovitslab.org)

Today in partnership with @emblebi, we’re releasing predicted structures for nearly all catalogued proteins known to science, which will expand the #AlphaFold database by over 200x - from nearly 1 million to 200+ million structures: dpmd.ai/AF-22-TW 1/
Check out our collaboration with Anton Zavialov's group and others on the zigzag spring-like structure of an archaic chaperone-usher pilus in @Nature: doi.org/10.1038/s41586… Congrats to @NPakharuk, Henri Malmi and all authors!
Last days for abstract submission. Show us your cool science at the event. In particular encouraging ECR as well!!!
One week to go until abstract submissions close for the Protein Secretion at the Host–Pathogen Interface meeting, taking place in Belfast, 3–4 November. View the invited speakers, and submit your abstract online by 15 July: microb.io/3npAW6S #HostPathSecretion22
In a recent Science study, researchers present a near-atomic composite structure of the human #NuclearPoreComplex’s ~64-megadalton symmetric core. The findings provide a basis for future functional studies. fcld.ly/wgoa4cj
Excited to finally share our story on the central role of PPE68 in ESX-1 secretion. I hope you enjoy reading it! #T7SS #mycobacterium
The ESX-1 substrate PPE68 has a key function in the ESX-1 mediated secretion in Mycobacterium marinum biorxiv.org/cgi/content/sh… #bioRxiv
Finally Online our paper on the molecular and cellular insight into Escherichia coli SslE and its role during biofilm maturation. Great team effort and fantastic collaboration with the Garnett group and Pau Bernadó nature.com/articles/s4152…

Here is the first preprint from our lab - which was only possible via a number of fantastic collaborations @FedorovaLab @PrattGroup @GarciaSaez_Lab @Conrad_Lab and a number of tweeterless colleagues. Please check this out and let us know what you think! #ferroptosis #preprints

We still have a fully-funded Ph.D. position open. If you are interested in developing antibody-based strategies to trigger ferroptosis in B-cell malignancies and exploit them in the context of immunotherapies - please get in touch. Previous mouse work exp is a plus!
Short term postdoc position available to work on the Tat pathway! Please RT jobs.ncl.ac.uk/job/Newcastle-…
When did you leave the RVZ?😅 Congrats!
Just out.. our paper with brilliant collaborators @lab_baum @BaumBuzz showing ESCRT-III-like membrane remodelling proteins in bacteria… #Vipp1 #PspA 😎 cell.com/cell/fulltext/…

Type VII secretion systems: structure, functions and transport models In this Review, Rivera-Calzada et al. provide an overview of the architecture of T7SSs, their functions and transport models nature.com/articles/s4157… @llorcalab @CNIOStopCancer @GeibelLab
Great to see the #cryoID of Endospore Appendages from pathogenic Bacilli out in @embojournal embopress.org/doi/abs/10.152… Built to last where others perish. Amazing architecture and self-assembly properties that results in flexible yet extremely resilient protein nanofibers.
We are very happy to make visible our review: “Understanding the invisible hands of sample preparation for cryo-EM” celebrating Protein Data Base 50th: the future of structural biology rdcu.be/ckjy8
Excited to share our research on bidirectional promoters in @NatureMicrobiol today! Here we show that transcription in bacteria isn't as 'straightforward' as we thought... 🧵 nature.com/articles/s4156…
