TIME DELAY1.0:LuxI(RBS1.0)->LuxR->LuxPR->GFP
We built this part by biobricks from the DNA distribution kit plates 2012.
This part contains BBa-K750001 and BBa_K750007. Arabinose will activate the promoter Pbad, which will cause production of protein LuxI and LuxR. The protein LuxI, LuxR and LuxPR make up the quorum sensing system, which leads to the expression of GFP.

LuxI expression device activated by arabinose(Regulated by RBS of 1.0 strength)
We built this part by biobricks from the DNA distribution kit plates 2012
This part contains Pbad promoter, rbs of 1.0 strength, LuxI producer and double terminator. Once the promoter Pbad is activated by arabinose, this part can produce LuxI protein.
This part contains part9, LuxPR and RBS1.0 GFP TT. When arabinose is added, the LuxR protein will be produced. And when this part is ligated with part4(or 5,6,7,8), the GFP will express because of the influence of quorum sensing system.

RBS (Elowitz 1999) -- defines RBS efficiency
Varies from -6 to +1 region from original sequence to accomodate BioBricks suffix. 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.

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. .

Promoter (luxR & HSL regulated -- lux pR)
Promoter activated by LuxR in concert with HSL 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.
This promoter is based on the Vibrio fischeri quorum sensing gene promoters. Two genes LuxI and LuxR and transcribed in opposite directions as shown below. The original sequence from which the parts <bb_part>BBa_R0062</bb_part> and <bb_part>BBa_R0063</bb_part> were derived is shown in the picture below. <img src="<bb_file>Image1.gif</bb_file>" width="614" height="362">
Double terminator consisting of BBa_B0010 and BBa_B0012
LuxR expression device activated by arabinose
This part contains Pbad promoter, rbs of 1.0 strength, luxR producer and double terminator. Once the promoter Pbad is activated by arabinose, this part can produce luxR protein.

The sequence was obtained by applying all mutations that upregulated AraC binding and subsequent promoter activity listed in reference [1].
pBAD is an E.coli promoter that is induced by L-arabinose. K206000 is a mutagenized pBAD promoter that is responsive to lower concentrations of arabinose than wild type (<partinfo>I13453</partinfo>) and, additionally, exhibits a higher maximum of protein expression as measured by coupling to a fluorescent reporter.
There were no special design considerations.
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.
Transcriptional terminator consisting of a 64 bp stem-loop.
In complex with HSL, LuxR binds to the Lux promoter, activating transcription from Pr <bb_part>BBa_R0062</bb_part>, and repressing transcription from Pl <bb_part>BBa_R0063</bb_part>. 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 activator, LuxR complexed to HSL. Two molecules of LuxR protein form a complex with two molecules the signalling compound homoserine lactone (HSL). This complex binds to a palindromic site on the promoter, increasing the rate of transcription.
2 silent point mutants were introduced in the coding sequence to remove internal XbaI and PstI sites. Mutation sites were chosen to replace codons commonly used in E. coli with codons used at a similar frequency.
