ProteomicsAdaptive β-lactam resistance from an inducible efflux pump that is post-translationally regulated by the DjlA co-chaperone

Caulobacter crescentus chaperone efflux pump 
GenomicsCell cycle transition from S-phase to G1 in Caulobacter is mediated by ancestral virulence regulators
We report that ancestral zinc-finger-domain transcriptional regulators, previously reported to control virulence/symbiosis, implement a cell cycle (SM-bM-^FM-^RG1) transcriptional switch. To unravel how this G1-phase transcriptional program is reinstated during a primitive cell cycle, we first de...

GenomicsRegulatory landscape of a dimorphic and obligate intracellular pathogen
Both prokaryotic and eukaryotic organisms take deterministic decisions to reprogram cell fates. A macroscopic manifestation of such an event is the remodelling of the cells’ morphology and it typically is governed at the molecular scale by massive reorganization of the cellular transcriptome. With...

GenomicsGrowth control switch by a DNA damage-inducible toxin-antitoxin system in Caulobacter
Bacterial toxin-antitoxin systems (TASs) are thought to respond to various stresses, often inducing growth-arrested (persistent) sub-populations of cells whose housekeeping functions are inhibited. However, it is not always clear whether specific targets of orthologous RNAse toxins are responsible f...
