REACTIONS
Based on the law of mass action that states that the rate of a chemical reaction is proportional to the product of the concentrations of the reactants, the whole modified ecosystem is represented in the next chemical reaction network

MATLAB
To be able to visualize the numbers obtained from modeling, we simulated the behavior described before, on the MathWorks® platform MATLAB. Thanks to these simulations we were able to compare the graphs between the variables concentrations inside a Wild Erwinia amylovora and a Modified one. The results were the following

OPEN PROBLEMS
Through the model we described the E. amylovra's behavior changes caused by the aiiA enzyme insertion. Nevertheless, the project is based on the combination of three enzymes to reach our goal and inhibit the E. amylovra's virulence factors. We are aware that there is more to do, so with a little help from our friends from IONIS Paris, the yhjH enzyme model is now a future project. They helped us to 3D model the yhjH enzyme (shown below) and to take certain conditions under consideration to its proper activity. Thanks to this edition model, the unregulated gene inhibition over a regulated one can be taken as a basis, and together with the 3D simulation, a second model could be achieved.
