LsrK needs to be constitutively expressed in order to receive the AI-2 signal. LsrR acts as its own repressor, so the reporter should not be activated until the AI-2 signal is received. Once LsrR binds to AI-2 molecule, the LsrR gene is activated and the positive feedback loop is initiated, which also turns on the reporter gene.

-We will test by ligating each of these constructs together with the 3 different lac promoters and the 4 different Lac proteins. We will measure the output of GFP to characterize the strength of each promoter and protein. We will have 12 constructs all together.

Once LsrR binds to AI-2 molecule, the LsrR gene is activated and the positive feedback loop is initiated, which also turns on the reporter gene.

Testing Crosstalk between Lux and Las

1) Mix LuxI sender cells with LasR receiver tester cells: negative control
2) Mix LasI sender cells with LuxR receiver tester cells: negative control
3) Mix LuxI sender cells with LuxR receiver tester cells: experiment we hope will glow green
4) Mix LasI sender cells with LasR receiver tester cells: experiment we hope will glow green
5) Verify LuxR receiver tester cells don't glow solo
6) Verify LasR receiver tester cells don't glow solo

AND gate using pTetLac promoter

We have successfully built the pTetLac AND promoter: K091101.
This is sequence verified.
Now we need the various LacI proteins (I12, X86 and I12+X86 variants).
We need tetR repressor protein. We have tried to get it from the paper registry.
We need to see if this AND gate works as designed.
We need to test output to see if the two halves are balanced.

Building XOR Gate

List of auto-inducers and their catalog numbers.

Davidson Approach

Here is an idea Malcolm and Laurie developed.

Everyone please look at this and ask questions and find holes in it now so we don't waste time building something that won't work.
Error creating thumbnail: Unable to save thumbnail to destination

The idea is to have two mirrored halves of the system. LasR is regulated by PAI-1 {3-oxododecanoyl-HSL (3OC12HSL)} and LuxR is activated by AI-1 {3-oxohexanoyl-homoserine lactone (3OC6HSL)}. There is a potential problem in that the Lux half is more likely to get positive feedback than the Las half. This MAY not be a problem because 0/0 is leaky so we put a weak RBS to minimize leaky protein production. Also, if we add AI-2 and AI-1 is produced by leak, then the entire system shuts down. The repressor site is located between -35 and -10 of the promoter. The activator binding site is upstream of -35. This has been documented by Egland and Greenberg

Sequences we will need to make this XOR gate.

Testing XOR Gate

We will need to have constitutive LasR and LuxR made in these cells.
Then we will need to hit them with the two chemicals AHL types and commercial sources.
