*To mimic Lotka-Volterra, the predator construct is split into a 'sensing part' and 'killing part'.
*The purpouse for building and testing this part is so we can characterize the production of AHL-lactonase
*The sensing part of the predator produces AHL lactonase as a function of the AHL produced by the prey
*The Aiia gene has been replaced with GFP to allow direct measurement of protein production
*In this part the AiiA gene has been replaced with the reporter gene GFP to allow the measurement of the production of GFP as a function of AHL.
*From this data we can create a transfer function where AHL is the input and GFP the output
*The resulting transfer curve will be used to extract parameters Vmax and Kd to characterize the part and for use in our modelling.
*Making the assumpion that AHL-lactonase is transcribed at the same rate as GFP we can use the transfer curve to extract parameters to allow characterization of the sensing part of the predator
*This part will form the receiver of the final predator construct
*The part will be used to form the sensing part of the final predator construct

Motivation

  • The purpouse for building and testing this part is so we can characterize the production of AHL-lactonase
  • The Aiia gene has been replaced with GFP to allow direct measurement of protein production
  • From this data we can create a transfer function where AHL is the input and GFP the output
  • Making the assumpion that AHL-lactonase is transcribed at the same rate as GFP we can use the transfer curve to extract parameters to allow characterization of the sensing part of the predator
  • The part will be used to form the sensing part of the final predator construct
