  • Who are we?

    We are iGEM 2013 team of TU Delft, Netherlands. We are working on the production of antimicrobial peptides in order to kill multiple resistant Staphyllococcus aureus.

  • Sensing AIP

    The sensing part of the Agr system was engineered in E.coli. In that way E.coli detects the AIPs that are produced by the Agr system of S.aureus and the peptide is produced.

  • Peptide Production

    E.coli detects S. aureus by its own quorum sensing system, and at that moment inactivated antimicrobial peptides are started to be produced

  • Timer

    With the use of a timer the peptide will be activated by cleavage of an inactivating tag. With the use of a timer, high concentrations of peptide can be delivered very locally in order to efficiently kill MRSA.

  • Kill Switch

    In order to ensure the safety of the system, the peptide-activating protease is combined with a kill switch that will kill our E. coli.
