Constitutively expressed transcription regulator LasR + LVA

The device consists of a strong constitutive promoter (BBa_J23100) combined with RBS (BBa_B0032) and the encoding region of the transcription regulator LasR (BBa_C0079).This results in a constitutively high transcription level of LasR.

Usage and Biology

In combination with N-oxo-dodecanoyl-HSL synthesized by LasI, LasR is able to activate the inducible promoter of the las quorum sensing system of Pseudomonas aeruginosa.

LasR binds to specific sequences in the promoter region and in the presence of N-oxo-dodecanoyl-HSL it activates gene expression (Medina et al., 2003).
