For Staphylococcus aureus it was shown previously that aminocoumarinecoumarin antibiotics such as novobiocin lead to immediate down-regulation of recA expression and thereby inhibition of the SOS response, the mutation frequency and the recombination capacity. Aminocoumarinecoumarin function by inh...

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, ...

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...
