Mutations along the signaling pathway of the E. coli sensor histidine kinase PhoQ alter signal gain and ligand-sensitivity by altering thermodynamic allosteric coupling between domains.
Deep and comprehensive proteomic resource of human intervertebral disc at high spatial resolution with a methodological flow reveals new insights in disc homeostasis and degeneration.

Transcriptome-scale RNA imaging and lifetime measurements reveal that the E. coli transcriptome is spatially organized and that this organization modulates the post-transcriptional fate of bacterial mRNAs.
Leaf-cutting ants use their fecal fluid to vector enzymes produced by their fungal symbiont to degrade plant biomass with a combination of degradation enzymes and Fenton chemistry.
Genetic and biochemical analyses reveal that the bacterial nucleases PNPase and RNase R work in concert with a type III-A CRISPR-Cas immune system to process small CRISPR RNAs and ensure robust immunity against foreign nucleic acid invaders.
The first successful de novo design of a homo-trimeric protein that binds a C3 symmetric small molecule larger than a metal ion is an advance for computational protein design.
