The (p)ppGpp synthetase RelA contributes to stress adaptation and virulence in Enterococcus faecalis V583

Abstract excerpt

Guanosine penta- and tetraphosphate [(p)ppGpp] are two unusual nucleotides implied in the bacterial stringent response. In many pathogenic bacteria, mutants unable to synthesize these molecules lose their virulence. In Gram-positive bacteria such as Enterococcus faecalis, the synthesis and degradation of (p)ppGpp mainly depend on the activity of a bifunctional enzyme, encoded by the relA gene. By analysing...
