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. false true _296_ 0 4243 9 Not in stock false zxc false Pei-Chuan Chu component2262848 1 BBa_C0012 component2262852 1 BBa_B0034 component2262859 1 BBa_J61048 component2262855 1 BBa_C0062 component2262844 1 BBa_J23106 component2262846 1 BBa_B0034 annotation2262844 1 BBa_J23106 range2262844 1 1 35 annotation2262859 1 BBa_J61048 range2262859 1 2030 2142 annotation2262846 1 BBa_B0034 range2262846 1 44 55 annotation2262855 1 BBa_C0062 range2262855 1 1241 1996 annotation2262852 1 BBa_B0034 range2262852 1 1223 1234 annotation2262848 1 BBa_C0012 range2262848 1 62 1189 BBa_C0062 1 luxr luxR repressor/activator, (no LVA?) 2003-01-31T12:00:00Z 2015-08-31T04:07:23Z <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.
