Signaling module
The signaling module allows our bacterial strain to integrate the input signal = the pathogene presence.Stapylococcus aureus secrete a protease nom de la protéase which cut a specific amino-acids sequence. This specific sequence can be used as a linker between a membrane protein and a dipeptide.
Once S. aureus is present, the linker is cut by the protease and the dipeptide is released.
The dipeptide bind to his receptor which is an engineered receptor:
- the extracellular part is the extracellular part of Tap, a dipeptide receptor involved in the chemotaxism
- the intracellular part is the intracellular part of EnvZ, a kinase involved in the osmoregulation
Once the dipeptide is bound, the EnvZ part allows the phosphorylation of OmpR, a transcriptional activator. It can now activate the pOmpC promotor
