<em>V. fischeri</em> <genbank>AF170104</genbank>
Released HQ 2013
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>. <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 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.</p>

Varies from -6 to +1 region from original sequence to accomodate BioBricks suffix. <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.

represillator of Elowitz and Leibler (2000)
Released HQ 2013
Coding region for the LacI protein with an LVA degradation tail and without an RBS. LacI binds to the pLac regulator <bb_part>BBa_R0010</bb_part> and PLlac01 hybrid regulator <bb_part>BBa_R0011</bb_part> and inhibits transcription. IPTG (Isopropylthiogalactoside) binds to LacI and inhibits its operation, therefore promoting transcription.</P> <P>A rapid degredation tail (LVA) has been added to improve the High to Low performance of this part.</P>

To inhibit transcription of the LacI promoter (pLacl, BBa_R0010), we have to encode LacI protein (BBa_C0012). LacI protein can bind to pLacI and repress the expression, but lactose, which repress lacI binding, act as a switch opening the expression. Therefore, the inter-regulation could be a timer device, so LacI is a key component of first device. The second gene is the LuxR, which is a membrane receptor, takes external AHL compound to pass down the signals. We use the LuxR as our bacteria-sensor to sense other bacteria in the environment. For selecting other parts, we choose one kind of constitutive promoter family(BBa_J23106) as the promoter, and the expression amount of this promoter is moderate comparing others in the family. Furthermore, we use the commom ribosome-binding site(BBa_B0034) and the terminator(BBa_B0014), which is a special double terminator, to ensure the transcription would exactly stop.
