'''Engineering a Molecular Predation Oscillator''', the iGEM project 2006 of Imperial College London, provides a new approach to creating a stable biological oscillator: It follows an engineering-based cycle of specification, design, modelling, implementation and testing/validation. The innovative design of the oscillator relies on predator-prey dynamics based on the Lotka-Volterra model. </font>

Following the design of the oscillator, a full theoretical analysis and detailed computer modelling of the Lotka-Volterra dynamics was carried out. These studies showed that it is theoretically possible to provide a stable oscillator. Because all components as well as the overall oscillator were modelled, its behaviour could be accurately predicted. Our team successfully built the functional parts, thus providing the building blocks for the final oscillator. All parts created were experimentally tested and their characterization could be used to feedback information into the modelling.

Achievements


  • Derivation of the complete dynamical model, describing the main biochemical reactions driving our oscillator
  • Full theoretical analysis and detailed computer simulations, validating our design with regard to our specifications
  • Successful building and characterization of functional parts, providing the building blocks for the final oscillator

Secondary Projects

PoPs Blocker Biological to Electrical Interface

As a method of controlling the activation of the positive-feedback loop in our predator-prey based oscillator, we successfully created this part, which can be used as a general Pops Blocker:

  • This part is placed downstream of a promoter and prevents any Pops from the promoter passing through this part
  • When an accompanying Cre Recombinase plasmid becomes activated, the enzyme produced will permanently cut a section of DNA from the plasmid containing this part
  • Only then, the polymerase can pass through this part and transcribe downstream genes.

We also worked on a Biosensor for measuring AHL concentrations in order to establish a Biological to Electrical Interface this summer.

  • Using an enzyme to hydrolize the lactone AHL would result in a local change in pH
  • Measuring the change in pH gives a measurement of how much AHL is present.
