Landmine Module
An important part of our iGEM project is a promoter sensitive to landmines, first described by Yagur-Kroll et al. [1]. We will use two of the promoters described in this paper, ybiJ and ybiFB2A1, in our project. Of these promoters, not much is known other than the fact that they have a DNT/TNT-dependent response curve (see figure 1). Our goal was to find a model which would be able to reproduce the response curves of both promoters.
Our first approach was to solve a system of Ordinary Differential Equations (ODEs) resembling the transcription and translation of a gene activated by the DNT-sensitive promoter. The ODEs were derived from the following system of reactions: $$ S+E \xrightleftharpoons[k_{IS}]{k_{SI}} I \cdot E \xrightleftharpoons[k_{PI}]{k_{IP}} P+E $$
