Description
A transcription factor [LuxR] (BBa_C0062) that is active in the presence of cell-cell signaling molecule 3OC6HSL is controlled by a tetR regulatable operator (BBa_R0040). Device input is 3OC6HSL. Device output is PoPS from a LuxR-regulated operator. If used in a cell containing TetR then a second input signal such as [http://openwetware.org/wiki/ATc aTc] can be used to produce a logical AND function.

Characteristics
Input Swing: 0.1 - 1000 nM 3OC6HSL, exogenous L/H Response time: 9.5 mins (50% of max. output)
Output Swing: 21±3 - 590±9 GFP molecules cfu-1 s-1 Genetic Stability: >92/74 generations (Low/High Input)
Switch Point: 1E-8 M 3OC6HSL, exogenous Performance Stability: >92/74 generations (Low/High Input)
