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

Excited to share our latest story in Nature. We developed a high-throughput cellular stretch system to look for genes regulating membrane rupture under tension, and found an amazing small protein called NINJ1 that weakens the membrane for rupture!

I’m thrilled to finally share this preprint! It contains a WOW Cryo-EM structure (likely one of the strongest protein fibers known to man 🤯), but we’ve also untangled its biological function: a novel type of virulence factor💀!

In our latest preprint we used cryoEM to solve the structure of A-ENA fibers and show that they are stabilized by 10 isopeptide bonds per monomer. A-ENA couples the spore to the cry-toxins, and in doing so increases the virulence of Bacillus thuringiensis: www.researchsquare.com/article/rs-6...

Protein production for cryoEM structure determination just got a lot cheaper - high resolution structure from half a plate of HEK cells with the "MIcro ISolation (MISO)" microfluidics-based approach. Congrats to the Brunner and Efremov labs in Brussels! www.biorxiv.org/content/10.1...

Cryo-EM structures of mammalian membrane proteins from a single cell culture dish?

Yes, Micro ISOlation (MISO) sample preparation makes it possible.
