Prey Molecule Generator (AHL) + GFP Reporter

Prey Genotype + Reporter

Usage and Biology

Usage:

  • This part was created by iGEM@Imperial 2006 to be used as the prey part in their 2006 project [http://openwetware.org/wiki/IGEM:IMPERIAL/2006 'Engineering a Molecular Predation Oscillator'] to generate a the production of Acyl-Homoserine Lactone (a quorum sensing molecule) using a positive feedback loop.

Biology:

  • The positive feedback loop relies on leaky expression of the tetR promoter which causes production of luxR. AHL already present in the cell forms a complex with luxR and lux pR promoter, expressing luxI and GFP. LuxI enzymatically produces AHL.
  • The behaviour of this part was successfully modelled, generating a [http://openwetware.org/wiki/IGEM:IMPERIAL/2006/project/Oscillator/project_browser/Prey_Construct/Modelling transfer curve of AHL vs. Time].
