Inhibition of Staphylococcus aureus pathogenesis in vitro and in vivo by RAP-binding peptides.

Staphylococcus aureus cause many diseases by producing toxins, whose synthesis is regulated by quorum-sensing mechanisms. S. aureus secretes a protein termed RNAIII activating protein (RAP) which autoinduces toxin production via the phosphorylation of is target protein TRAP.
