Description
Device composed of two modules, separated by a double terminator (BBa_B0014): First, a positively regulated Lux Promoter (BBa_R0062) drives the expression of a red fluorescent protein (BBa_E1010) with a medium ribosome binding site (BBa_B0032); second, a constitutive expression of Lux Receptor (BBa_C0062) and a green fluorescent protein (BBa_E0040) in tandem under a tet promoter (BBa_R0040) and both proteins with a weak RBS (BBa_B0033). This inducible device produces the expression of a red fluorescent protein upon the addition of lactone (C6-HSL) and the presence of the Lux Receptor in the cell.
This composite part has been used and extensively described in a paper published in Nucleic Acid Research in 2014 (open access). For further details and part experience, please freely download the paper or contact the authors. The reference and link are:

Notes
LuxR coding sequence and GFP coding sequence are in tandem, both placed after a Ribosome Binding Site sequence.
