Out today @ Science: TIR signaling activates caspase-like immunity in bacteria

We report a new immune signaling molecule: N7-cADPR. Produced by phage-induced TIRs and activates a defensive bacterial caspase

Congrats Francois Rousset, Ilya Osterman and coauthors!

We identified a #VHH antibody that allosterically inhibits sialic acid binding by the #TRAP transporter #SBP VcSiaP.
Thanks to the team including: @philipphendricks.bsky.social @scbinder.bsky.social @gavinhthomas.bsky.social @gha14.bsky.social

Substrate binding proteins and nanobodies - that’s protein biochemistry heaven. In our new publication we characterized a nanobody that allosterically inhibits the SBP VcSiaP.
Amazing job by @nschneberger.bsky.social and thanks to everyone involved! As always a great team effort!

This is the first fully open source release of a AF3 like model. Awesome! Congratulations to the team.
Thrilled to announce Boltz-1, the first open-source and commercially available model to achieve AlphaFold3-level accuracy on biomolecular structure prediction! An exciting collaboration with Jeremy, Saro, and an amazing team at MIT and Genesis Therapeutics. A thread!
