Staphylococcus aureus is a major human pathogen and many of the strains are resistant to conventional antibacterial treatment. The bacteria cause disease largely due to the production of multiple toxins, whose synthesis is controlled by an RNA molecule termed RNAIII. The production of RNAIII is induced by quorum sensing systems, one of them containing the protein RNAIII activating protein (RAP). Here...
Here, we reported a conformation-constrained peptide library, that was constructed based on the scaffold of a 29 amino acids peptide derived from insect defensin A. The peptide scaffold was designed utilizing the InsightII molecular modeling software and then displayed on M13 filamentous bacteriophage by fusion with coat protein III. The library was constructed by randomization of seven positions...
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. Mice vaccinated with RAP were protected from S. aureus infection, suggesting that RAP is an useful target for selecting potential...
