Excited to see our work published in @ScienceAdvances
!

We present RBPseg, a method for structural prediction of #phage receptor-binding proteins.

We applied it to diverse tail fibers and validated the predicted structures using #cryoEM.

RBPseg: Toward a complete phage tail fiber structure atlas
RBPseg enables accurate modeling of tail fiber structure, providing the first comprehensive tail fiber structure atlas.

Thrilled to see Leyre’s PhD work finally out!

We reported the #cryoEM structures of an extracellular contractile injection system from P. luminescens in extended and contracted states, providing structural insight into its architecture and contraction mechanism 🔬

We have written up a tutorial on how to run BindCraft, how to prepare your input PDB, how to select hotspots, and various other tips and tricks to get the most out of binder design!

Super nice work! ✨️🪄
It was so great to hear it presented in Paris.
A new preprint led by Sonomi Yamaguchi in our lab describes a bacterial anti-phage defense system named Clover that uses nucleotide signals to both activate and inhibit host immunity.

Very cool system! 👀
Thrilled to see our Kiwa story out today! A membrane-associated supercomplex that senses infection and blocks replication and transcription.

Huge congratulations to Yi and Zhiying for bringing it home, to Thomas for starting us off, and to all the collaborators.
Kiwa is a membrane-embedded defense supercomplex activated at phage attachment sites
Zhang, Todeschini, and Wu et al. show that the bacterial defense system Kiwa senses phage attachment at the membrane and assembles a transmembrane complex that halts infection by blocking phage DNA re...

Very interesting paper from Feng Zhang's group describing that the origin of #CRISPR RNA targeting system Cas13 is from the HEPN RNA-Toxin antitoxin system Abi-F. It also Assert that Cas13an described from the Doudna lab earlier this year is in fact a Cas13 intermediate. www.cell.com/cell/fulltex...
Reprogrammable RNA-targeting CRISPR systems evolved from RNA toxin-antitoxins
Hybrid structure-sequence mining and biochemical/structural characterization trace the evolutionary origins of CRISPR-Cas13, elucidating how their RNA-guided mechanism likely evolved from an ancient s...

January 13th is the Day of the Defenders of Freedom of Lithuania 🇱🇹
To commemorate it, we run 9km around the Kastellet fortress in Copenhagen 🫶
