Released HQ 2013
This device produces luxR constitutively under the strong promoter Plambda, in absence of cI repressor. Plambda can be turned off by cI repressor and luxR production is inhibited.
This composite part can be considered as 3OC6-HSL in -> PoPS out device, because 3OC6-HSL binds luxR which turns on Plux promoter. The output PoPS can also be regulated by cI repressor, which modulates luxR expression.
Strong RBS (efficiency=0.6).
Artificial 39 bp terminator (efficiency=0.99).

The cI regulated promoter is based on the pR promtoer from bacteriohage lambda. The promoter has two two DNA binding sites for lambda cI repressor <bb_part>BBa_C0051</bb_part>. cI binding results in repression of transcription. The specific sequence used here is based on the cI repressible promoter used in the Elowitz repressilator (and references therein).</P>

<em>V. fischeri</em>
Released HQ 2013
Promoter activated by LuxR in concert with HSL</p> <p>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 LuxR activator protein complexed with the autoinducer, 3-oxo-hexanoyl-HSL. Two molecules of LuxR protein form a complex with two molecules of the signalling compound homoserine lactone (HSL). This complex binds to a palindromic site on the promoter, increasing the rate of transcription.

Varies from -6 to +1 region from original sequence to accomodate BioBricks suffix ("orig" in figure 4-14 of Ron Weiss thesis). <p>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.
