Promoter (luxR & HSL regulated -- lux pL)
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
Usage and Biology
Medium strength promoter in the absence of LuxR/HSL. [jb, 5/24/04]
