The connection between peptidoglycan remodeling and cell division is poorly understood in ellipsoid-shaped ovococcus bacteria, such as the human respiratory pathogen Streptococcus pneumoniae. In S. pneumoniae, peptidoglycan homeostasis and stress are regulated by the WalRK (VicRK) two-component regulatory system, which positively regulates expression of the essential PcsB cysteine- and histidin...
This paper contributes to the development of the capabilities approach by showing that capabilities can, counter prevailing wisdom, be measured. By operationalising the capabilities element of Sen’s non-welfarist theory, the paper develops the data required by this novel approach to welfare economics and by exploring relations to life-satisfaction (happiness) it also examines new economic co-va...
OBJECTIVES The aim of this study was to identify changes in the gene expression profile of Streptococcus pneumoniae in response to a subinhibitory concentration of penicillin in an effort to better understand mechanisms by which this organism copes with this stress. METHODS S. pneumoniae serotype 2 strain D39 was grown for 1 h in the presence or absence of penicillin at a concentration equiva...
Type II (proteic) chromosomal toxin-antitoxin systems (TAS) are widespread in Bacteria and Archaea but their precise function is known only for a limited number of them. Out of the many TAS described, the relBE family is one of the most abundant, being present in the three first sequenced strains of Streptococcus pneumoniae (D39, TIGR4 and R6). To address the function of the pneumococcal relBE2...
