Constitutively expressed transcription regulator RhlR + LVA

This device consists of a strong constitutive promoter (BBa_J23100) combined with RBS (BBa_B0032) and the coding region of the transcription regulator RhlR (BBa_C0071). This results in a constitutively high transcription level of RhlR.

Usage and Biology

In combination with N-buturyl homoserine lactone (N-buturyl-HSL) synthesized by RhlI, RhlR is able to activate the inducible promoter of the rhl quorum sensing System of Pseudomonas aeruginosa.

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