AHL induced expression of GFP (including luxR constitutive expression)

Figure 1. SBOL Visual representation of the device

This device was used to characterize the pLux promoter. It is an AHL induced transcriptional unit to express GFP together with a TU for the constitutive expression of LuxR. It was assembled with a one-pot Level 2 Golden Gate reaction using BsmBI type IIS endonuclease.

This device is composed of the following standardized composite parts from Valencia_UPV 2018 iGEM Team [http://2018.igem.org/Team:Valencia_UPV/Part_Collection Part Collection]:

• BBa_K2656122: a Level 1 transcriptional unit expresing GFP under the control of the pux promoter (Golden Braid compatible)
• BBa_K2656114: a Level 1 transcriptional unit constitutively expressing luxR gene (Golden Braid compatible)

Usage and Biology

This composite part, together with K3893029, is an intermediate composite part to assemble the release system device (K3893030) of our Agrobactory 593. It includes a TU that expresses GFP under the control of the pLux promoter and a TU that expresses LuxR constitutively. It is the first half of our population oscillator release device.

Characterization

Following a standard experimental procedure and the IGEM 2018 Interlab calibration for Particles and MEFL we obtained the temporal behavior of the device for different inducer concentrations.

Experimental results for characterization of pLux promoter.

Final GFP expression levels for different AHL inducer concentrations.

We used this part to characterize the Golden Braid version (K2656003) of pLux promoter (R0062) made by [http://2018.igem.org/Team:Valencia_UPV Valencia_UPV 2018 Team]. Check our experimental page for more details.
