Very happy that our work on the T6SS ADP-ribosylcyclase toxin made the Cover at JBC @asbmb.bsky.social y.social ! Congratulations Julius @jmartinkus.bsky.social for designing this Cover !

Poly-immunity arrays associated with Rhs toxins confer wide protection against competitors
Martinkus et al. show that Photorhabdus and Xenorhabdus species encode arrays of immunity
genes whose protein products neutralize toxins secreted by competitors. These arrays,
often linked to Xer pass...

We propose immuno-centric view of secreted polymorphic toxin diversification and involvement of novel XPC systems in this process! Fantastic work of @jmartinkus.bsky.social with lab of @cascaleslab.bsky.social !
