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> false true _1_ 0 24 7 In stock false <P> <P>2 silent point mutants were introduced in the coding sequence to remove internal XbaI and PstI sites.

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
