Competence remodels the pneumococcal cell wall providing resistance to fratricide and surface exposing key virulence factors

V. Minhas, A. Domenech, D. Synefiaridou, D. Straume, M. Brendel, G. Cebrero, X. Liu, C. Costa, M. Baldry, J.-C. Sirard, C. Perez, N. Gisch, S. Hammerschmidt, L. S. Havarstein, J.-W. Veening

This study shows that competence in Streptococcus pneumoniae is crucial for virulence by increasing surface exposure of virulence factors and providing resistance to fratricide.

Prevention of EloR/KhpA heterodimerization by introduction of site-specific amino acid substitutions renders the essential elongasome protein PBP2b redundant in Streptococcus pneumoniae.

A. Ruud Winther, M. Kjos, G. A. Stamsas, L. S. Havarstein, D. Straume

This paper shows that disrupting EloR/KhpA heterodimerization in S. pneumoniae makes the elongasome redundant, highlighting the complex's role in regulating cell division.
