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>

Quorum sensing is used by a number of gram-negative bacterial genera to regulate expression of specific sets of genes in a cell density-dependent fashion. We constructed the part which expresses LuxI and LuxR upon induction by isopropyl-b-D-thiogalactopyranoside (IPTG). There are two regulatory genes involved in quorum sensing, the I and R genes. The I gene directs the synthesis of an acyl-homoserine lactone (AHL) signal molecule termed the autoinducer. The R gene codes for a transcription factor that is responsive to the N-acyl HSL signal. Cells are permeable to this signal, and thus high cell densities are required to achieve a critical concentration of the autoinducer required to bind the luxR product, which will be combined with lux pR and then the expression downstream genes could be started.
Site-directed mutagenesis has been used to modify the promoter lux pR in this signalling device. We have generated three point mutants by site-directed mutagenesis, designated lux pR-3 (BBa_K658006), lux pR-5(BBa_K658007) and lux pR-3/5(BBa_K658008).
This signalling device is usually used to connected with some protein coding sequence,The promoter lux pR-3 (BBa_K658006) at the end of this sequence regulates the expression of downstream genes.

This signalling device is based on the quorum sensing system in V. Fischri. Different from an autoinduction system, this signalling circuit starts only at the presence of inducer IPTG which does not exist in the natural QS system.

lux pR-3
position 3 mutated promoter lux pR-3 (luxR & HSL regulated)
2011-09-30T11:00:00Z
2015-05-08T01:13:02Z
The position 3 mutated promoter lux pR-3 is based on promoter lux pR (BBa_R0062).
The position 3 mutated promoter lux pR-3 is a product of site-directed mutagenesis of promoter lux pR (BBa_R0062). The promoter lux pR is based on the Vibrio fischeri quorum sensing gene promoters. The position 3 mutated promoter lux pR-3 gives a higher expression of downstream genes in an autoinduction system. In another word, the lux pR-3 has a higher efficiency than the lux pR. Similar to promoter lux pR, the expression is up-regulated by the action of LuxR protein combined with the signal molecule HSL.

Inverting regulatory region controlled by LacI (<bb_part>BBa_C0010</bb_part>, <bb_part>BBa_C0011</bb_part>, etc.) <p> The PLlac 0-1 promoter is a hybrid regulatory region consisting of the promoter P(L) of phage lambda with the cI binding sites replaced with lacO1. The hybrid design allows for strong promotion that can nevertheless be tightly repressed by LacI, the Lac inhibitor (i.e. repressor) (<bb_part>BBa_C0010</bb_part>) ([LUTZ97]). The activity of the promoter can be regulated over a >600-fold range by IPTG in E.Coli DH5-alpha-Z1 (same paper reference).

<P> <P>hybrid promoter design to create strong promoter that is, at the same time, highly repressible. note that the upstream operator installed in this hybrid is slightly different than the one in the original source (Lutz and Bujard, 1997). the most upstream operator region is slightly truncated in the represillator version, so that both operators in the hybrid are the same sequence. see references for details. also, the sequence has been truncated after the transcriptional start site.<P>LacI binds to this regulator. This part is incompatible with species containing active LacI coding regions. Lactose and IPTG disable the operation of LacI and increase transcription. This part is incompatible with environments containing lactose or lactose analogs.
