Many important bacterial non-coding RNAs and structural elements remain undiscovered. To help, @_David_Li, @garykbrixi, @mfgrp, @BrianHie & team introduce Minerva, which uses a genome language model to predict RNA base pairing, repeats, & other interactions from sequence alone.
Excited to share Minerva, our approach using genome language models for biological discovery! Using Minerva, we find that UG27 reverse transcriptase systems encode variable arrays of diverse ncRNAs with a shared structure, each templating a short DNA hairpin. With @garykbrixi.
Congratulations to Pujuan on receiving the Katharine McCormick Advanced Postdoctoral Scholar Fellowship! This fellowship supports exceptional postdocs pursuing faculty careers who have demonstrated a track record of uplifting women in science. Excited to see what’s next for you!
In contrast, Upx, despite sharing no sequence or structural homology with Avs2, is predicted to recognize phage terminase by binding unfolded terminase ATPase domains, via β-augmentation. (3/4)
They solved a 2.3 Å cryo-EM structure of Avs2 bound to phage terminase, with an unexpected ATP molecule bridging the two proteins at their interface. (2/4)
Immune recognition is far more universal than we thought! Our new paper uncovers ≥ 90 families of bacterial immune receptors that recognize conserved phage proteins. We also reveal how Avs7 recruits EF-Tu to assemble an immune complex.
Congrats to Hyunbin, Sofia, & others !!
