Transient inhibition of cell division in competent pneumococcal cells results from deceleration of the septal peptidoglycan complex

D. Juillot, C. Billaudeau, A. Barbotin, A. Lablaine, I. Mortier-Barriere, P. Polard, N. Campo, R. C. LOPEZ

The paper investigates how ComM, a membrane protein in Streptococcus pneumoniae, transiently inhibits cell division during competence by reducing septal peptidoglycan synthesis.

Fine-tuning cellular levels of DprA ensures transformant fitness in the human pathogen Streptococcus pneumoniae

C. Johnston, I. Mortier-Barriere, V. Khemici, P. Polard

This study shows that high DprA expression in Streptococcus pneumoniae is crucial for competence shut-off and transformant fitness, but not for DNA protection or RecA loading during transformation.
