Design genetic circuits
We have thus far focused our attention on signaling molecules used in quorum sensing systems of bacteria. The ones we will be using are as shown below:
*Inducer ⇒（synthesize) Signal molecule ⇒ Receptor
* LuxI ⇒ 3OC6HSL ⇒ LuxR → positive regulation * LasI ⇒ AI-1(3OC12HSL) ⇒ LasR → positive regulation * CinI ⇒ 3OH,C14:1-HSl ⇒ CinR → positive regulation * RhlI ⇒ AI-1(C4HSL) ⇒ RhlR → positive regulation * AgrB synthesizes AIP from AgrD ⇒ AIP diffuses and attaches to AgrC ⇒ AgrC phosphorylates
and activates AgrA which then promotes transcription at P2 and P3 promoters.
From now on,We have to do what I mention below
1.Investigate other cell-cell comunication systems (besides those used in quorum-sensing).
2.Check to ensure that system components are working properly.
3.Create new systems or implement additional cell functions.
4.Investigate the possibility and extent of cross talk between various signaling molecules.
