Constitutive RIP Generator. RIP - Quorum sensing inhibitor of Staphylococcus spp.

RIP or RNAIII inhibiting peptide is a heptapeptide capable of severely reducing the Qourum sensing(QS) abilities of Staphylococcus species [1]. RIP effectively works as an antibiotic in its inhibition of bacterial biofilm-formation. It is important to note that even though it has the effect of an antibiotic [1] on bacterial load, the mechanism is a novel one, and doesn't appear to induce bacterial resistance [1].

RIP has the sequence YSPXTNF and has been tested extensively in a synthetic (as in chemical synthesis) form for ability to inhibit bacterial infections in mice [1] and biofilm formation on human cells [2].

Usage and Biology

This generator is under constitutive expression by a TetR repressible promoter BBa_R0040.
