[HTML][HTML] The emergence of phase separation as an organizing principle in bacteria
Recent investigations in bacteria suggest that membraneless organelles play a crucial role
in the subcellular organization of bacterial cells. However, the biochemical functions and …

Bacterial chromosome segregation by the ParABS system
Proper chromosome segregation during cell division is essential in all domains of life. In the
majority of bacterial species, faithful chromosome segregation is mediated by the tripartite …

[HTML][HTML] ParB-type DNA segregation proteins are CTP-dependent molecular switches
M Osorio-Valeriano, F Altegoer, W Steinchen, S Urban… - Cell, 2019 - cell.com
During cell division, newly replicated DNA is actively segregated to the daughter cells. In
most bacteria, this process involves the DNA-binding protein ParB, which condenses the …

ATP-driven separation of liquid phase condensates in bacteria
Liquid-liquid phase-separated (LLPS) states are key to compartmentalizing components in
the absence of membranes; however, it is unclear whether LLPS condensates are actively …

Real-time imaging of a single gene reveals transcription-initiated local confinement
Genome dynamics are intimately linked to the regulation of gene expression, the most
fundamental mechanism in biology, yet we still do not know whether the very process of …

Dynamic ParB–DNA interactions initiate and maintain a partition condensate for bacterial chromosome segregation
In most bacteria, chromosome segregation is driven by the ParAB S system where the
CTPase protein ParB loads at the parS site to trigger the formation of a large partition …

Self-organization of parS centromeres by the ParB CTP hydrolase
ParABS systems facilitate chromosome segregation and plasmid partitioning in bacteria and
archaea. ParB protein binds centromeric parS DNA sequences and spreads to flanking …

ParB proteins can bypass DNA-bound roadblocks via dimer-dimer recruitment
The ParAB S system is essential for prokaryotic chromosome segregation. After loading at
parS on the genome, ParB (partition protein B) proteins rapidly redistribute to distances of …
