Promoter, Standard (luxR and HSL regulated -- lux pR)

[Note: This is the same part as R0062 except that the -10 and -35 sites and spacing have been changed to comply with BBa_S0001].

Promoter activated by LuxR in concert with HSL

The lux cassette of V. fischeri contains a left and a right promoter. The right promoter gives weak constitutive expression of downstream genes.This expression is up-regulated by the action of the LuxR activator protein complexed with the autoinducer, 3-oxo-hexanoyl-HSL. Two molecules of LuxR protein form a complex with two molecules of the signalling compound homoserine lactone (HSL). This complex binds to a palindromic site on the promoter, increasing the rate of transcription.


Usage and Biology

Medium strength promoter in the absense of LuxR/HSL. May not be well matched with other '10 series' promoters. [jb 5/24/04]
