Description
nahR (Pseudomonas putida, see BBa_K1031610) is expressed under the constitutive Pr promoter. It encodes a regulatory protein that activates the Psal promoter (see BBa_J61051) in the presence of salicylate. xylS2 (BBa_K1973002) is expressed from the Psal promoter in the presence of this molecule. This module provides a tight expression regulation by salicylate thanks to a two-step (NahR and XylS2) system.
Notes
We digested BBa_K1973002 as a vector (EcoRI and XbaI) and BBa_K1973005 as an insert (EcoRI and SpeI), and then we ligate them.
