Composite

Part:BBa_M36604

Designed by: Sibel Sayiner, Justo Caballero, and Shamik Mascharak   Group: Stanford BIOE44 - S11   (2012-12-05)


Heat-->PoPS (with postive feedback loop)

This composite part is a sensor that focuses on creating a positive feedback loop to increase the PoPS signal for a desired actuator further downstream. In this design, Sigma-32, a sigma factor turned on when E. coli experiences heat shock, is the transcription factor for the htpG Heat Shock Promoter (BBa_J45504). Once active, the inducible promoter allows for, with the assistance of a medium strength bicistronic RBS (BBa_M36405), the transcription of rpoH (BBa_M36888), the sequence for sigma-32. Such a design creates a positive feedback loop, creating more sigma-32 from a small initial heat exposure. This is solely done in order to generate a larger PoPS signal, which would allow for a greater production of one's desired downstream production.

Device input is heat exposure. Device output is a PoPS signal.
