In summary we have decided to pursue a mercury sequesting IGEM to be built from available parts, possibly.
1) Mercury transporter K205044
2) a glutathione part: possibly BBa_J61213 BBa_T20205 BBa_K289001 BBa_K289002 BBa_K289003...
Our task is to evaluate the gluthione parts for one that we can couple to the mercury transporter:

O.k. summary of our change of direction:
Since we have found some good examples of IGEMs that have been created to detect and/or sequester heavy metals we decided to shift gears and build a IGEM that can detect enteric bacteria: The idea is to build a device that can be use to sense bacteria in lake water. Lake Michigan beaches are susceptible to closure because of high E.coli counts. If we could develop an IGEM based upon the quorum sensing protein, autoinducer 2, the we could detect, indirectly the presence, even potentially the amount of bacteria in the water.

Possible promoter
LuxR is a constitutively expressed protein that can bind AHL. When bound to AHL it can stimulate transcription from the right hand lux promoter (pLuxR). In the natural system, this promoter controls transcription of the LuxI enzyme leading to a positive feedback loop that increases transcription from the right hand lux promoter. In addition controlling the transcription of luxI, the promoter also controls transcription of luciferase.
