The biobricks BBa_K266006 and BBa_K266000 where used to build this biobrick
Complex Quorum sensing circuit that receives the signal of PAI+LasR and AI+LuxR to control the production of LuxI and LasI enzymes.
The DNA of BBa_R0079 and BBa_F1610 biobricks where used.
This biobrick has a promoter inducible by PAI+LasR (BBa_R0079)and produces LuxI enzyme (BBa_F1610). This enzyme produces 3OC6HSL (AI).

RBS.1 (strong) -- modified from R. Weiss
Strong RBS based on Ron Weiss thesis. Strength is considered relative to <bb_part>BBa_B0031</bb_part>, <bb_part>BBa_B0032</bb_part>, <bb_part>BBa_B0033</bb_part>.
Varies from -6 to +1 region from original sequence to accomodate BioBricks suffix ("orig" in figure 4-14 of Ron Weiss thesis). No secondary structures are formed in the given RBS region. Users should check for secondary structures induced in the RBS by upstream and downstream elements in the +50 to -50 region, as such structures will greatly affect the strength of the RBS.

Derived from the TE terminator of T7 bacteriophage between Genes 1.3 and 1.4 <genbank>V01146</genbank>.
Transcription terminator for the E.coli RNA polymerase.
Suggested by Sri Kosuri and Drew Endy as a high efficiency terminator. The 5' end cutoff was placed immediately after the TAA stop codon and the 3' end cutoff was placed just prior to the RBS of Gene 1.4 (before AAGGAG). Use anywhere transcription should be stopped when the gene of interest is upstream of this terminator.
V. fischeri <genbank>AF170104</genbank>
Synthesizes 3OC6HSL, which binds to LuxR. The lux cassette of V. fischeri contains a left and a right promoter. The right promoter gives weak constitutive expression of downstream genes.This expression is up-regulated by the action of the Lux repressor, LuxR. Two molecules of LuxR protein form a complex with two molecules the signalling compound HSL. This complex binds to a palindromic site on the promoter, increasing the rate of transcription.
An LVA tail (sequence: AANDENYALVA) was added to increase protein degradation. .

Transcriptional terminator consisting of a 64 bp stem-loop.
The LuxR binding site is from BBa_R0062 and the pLas' promoter is from the region upstream of the LasI gene in Pseudomonas aeruginosa.
K091146 is a modified version of the pLas' promoter (BBa_K091117) containing the addition of a luxR binding site between the -35 and -10 regions. This promoter is expected to be activated in the presence of PAI-1 and LasR and repressed in the presence of AI-1 and LuxR.
The Lux box was placed adjacent to the LasR binding site with the aim of minimizing cross-talk in the presence of both PAI-1 and AI-1; since the LasR site should have a higher affinity, we hope that the binding of PAI-1 will competitively exclude the binding of AI-1.
