Description
K091146 is a modified version of the pLas' promoter (BBa_K091117) containing the addition of a luxR binding site between the -35 and -10 regions. This promoter is expected to be activated in the presence of PAI-1 and LasR and repressed in the presence of AI-1 and LuxR.
Notes
The Lux box was placed adjacent to the LasR binding site with the aim of minimizing cross-talk in the presence of both PAI-1 and AI-1; since the LasR site should have a higher affinity, we hope that the binding of PAI-1 will competitively exclude the binding of AI-1.
Source
The LuxR binding site is from BBa_R0062 and the pLas' promoter is from the region upstream of the LasI gene in Pseudomonas aeruginosa.
