Description
A transcription factor [LuxR] that is active in the presence of cell-cell signaling molecule 3OC6HSL is controlled by an operator [TetR]. Device input is 3OC6HSL. Device output is PoPS produced at a LuxR-regulated operator.

Usage
Full PoPS output at high 3OC6HSL levels and high plasmid copy [e.g., Part:pSB1A2] results in a reduced cell growth rate (see Load section). 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: ## nM 3OC6HSL, exogenous Output Swing: #-# PoPS Switch Point: 2 nM 3OC6HSL, exogenous L/H Latency: # minutes

Characterization Conditions
All characterization was performed on pSB3K3 using MG1655 as the characterization chassis. Cultures were grown in [http://openwetware.org/wiki/Endy:M9_media/supplemented supplemented M9 media] at 37C. Full characterization protocols can be found here.
