<em>V. fischeri.</em>
Released HQ 2013
The lux cassette of V. fischeri contains a left and a right promoter. The left promoter gives weak constitutive expression of downstream genes.This expression is down-regulated by the action of the Lux repressor, LuxR. 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 from Pr, repressing transcription from Pl</p>

<P> <P> 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.Includes most of Lux reulatory region, including the LuxR binding site which activates the right promoter. A putative LuxR autorepression binding site is also identified adjacent to the -10 site of the right promoter. This 2nd site has 55% identity with the first site. Putative inverted repeats (of size 18-27 bp) also exist between these two sites (not marked above), which may represent binding sites for other regulatory proteins. <p><img src="<bb_file>Image01.gif</bb_file>" width="614" height="362"><P>Unspecified.
