A toxin/antitoxin system targeting the replication sliding-clamp induces competence in Streptococcus pneumoniae Open
Streptococcus pneumoniae is a pathogenic bacterium capable of entering a cellular differentiation state, called competence, which enables it to acquire new genetic functions by natural transformation, as well as physiological functions suc…

Transient inhibition of cell division in competent pneumococcal cells results from deceleration of the septal peptidoglycan complex Open
Membrane protein ComM transiently inhibits cell division during the development of the competence state in the pathogenic bacterium Streptococcus pneumoniae , but the underlying molecular mechanisms remain unclear. Here we show that, in co…

Real-Time Nanoscale Investigation of Spore Coat Assembly in<i>Bacillus subtilis</i> Open
Spores of Bacillaceae , ubiquitous in soil, can withstand extreme conditions virtually indefinitely. The spore coat, one of the most sophisticated multiprotein complexes built by bacteria, protects the spore from environmental stresses and…

DivIVA controls the dynamics of septum splitting and cell elongation in <i>Streptococcus pneumoniae</i> Open
Bacterial shape and division rely on the dynamics of cell wall assembly, which involves regulated synthesis and cleavage of the peptidoglycan. In ovococci, these processes are coordinated within an annular mid-cell region with nanometric d…

Transient inhibition of cell division in competent pneumococcal cells results from deceleration of the septal peptidoglycan complex Open
Bacterial cells are known to produce inhibitors of cell division in response to stress responses and developmental programs. Knowledge of the underlying molecular mechanisms remains however largely limited. In this study, we investigated t…

study of the mechanism of division delay during natural genetic transformation in streptococcus pneumoniae Open
Streptococcus pneumoniae (le pneumocoque) est une bactérie commensale de l'homme pouvant provoquer dans certaines conditions des pneumonies, des méningites ou des septicémies. Les stratégies de lutte utilisées contre le pneumocoque reposen…

A high content microscopy screening identifies new genes involved in cell width control in<i>Bacillus subtilis</i> Open
How cells control their shape and size is a fundamental question of biology. In most bacteria, cell shape is imposed by the peptidoglycan (PG) polymeric meshwork that surrounds the cell. Thus, bacterial cell morphogenesis results from the …
