Continuous exchange of an inner-membrane ring component is required for assembly and function of the type III secretion system - Nature Communications
Bacteria use the type III secretion system (T3SS) to inject proteins into target cells. Here, Brianceau et al. show that a core structural component, SctD, exchanges between a T3SS-bound and a freely ...

What if even the core of bacterial nanomachines wasn’t static?
We found that the T3SS core protein SctD in Yersinia dynamically exchanges subunits — and this flexibility is essential for proper assembly & function.

Chromosome segregation dynamics during the cell cycle of Staphylococcus aureus - Nature Communications
Our understanding of chromosome organization and dynamics in spherical bacteria, such as Staphylococcus aureus, remains limited. Here, the authors show that chromosome replication and cell division cycles are not synchronized in S. aureus, with cells exhibiting two segregated origins of replication at the start of the cell cycle.
