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.
