Constitutive expression cassette for LuxR (J23100.B0034.C0062.B0015)

Part Structure

The Biobrick encodes LuxR (BBa_C0062) under control of the constitutive promoter BBa_J23100 followed by the ribosome binding site BBa_B0034. The transcription of luxR is terminated by the double terminator BBa_B0015.

Mode of Action

Two molecules of LuxR protein form a complex with two molecules of the signalling compound homoserine lactone (HSL) (e.g. AHL). This complex binds to a palindromic site on the promoter BBa_R0062, increasing the rate of transcription. So far, this LuxI/R system is the best characterized system of all cell-cell signaling systems.

Purpose

This Biobrick was designed for the [http://parts.mit.edu/igem07/index.php/ETHZ ETHZ iGEM 2007 project] and belongs to the constitutive part of the system. When complexed with HSL, the constitutively synthesized LuxR interacts with the double promoters BBa_I739103 and BBa_I739107 which are parts of composites BBa_I739006 and BBa_I739007 respectively.
