TranscriptomicsCodY in Staphylococcus aureus: regulatory link between metabolism and virulence gene expression
CodY is a conserved regulator in gram-positive organisms described to repress metabolic genes mainly involved in nitrogen metabolism but also to control the expression of virulence genes in pathogens. We constructed codY gene-replacement mutants in three unrelated S. aureus strains (Newman, UAMS-1, ...

TranscriptomicsThe stringent response of Staphylococcus aureus and its impact on survival after phagocytosis through the induction of intracellular PSMs expression
The stringent response is initiated by rapid (p)ppGpp synthesis, which leads to a profound reprogramming of gene expression in most bacteria. The stringent phenotype seems to be species specific and may be mediated by fundamentally different molecular mechanisms. In Staphylococcus aureus, (p)ppGpp s...

TranscriptomicsRNase Y of Staphylococcus aureus and its role in the activation of virulence genes
RNase Y of Bacillus subtilis is a key member of the degradosome and important for bulk mRNA turnover. In contrast to B. subtilis, the RNase Y homologue (rny/cvfA) of Staphylococcus aureus is not essential for growth. Here we found that RNase Y plays a major role in virulence gene regulation. Accordi...
