Iron Chelator

Here we present Fig 1 and 2 our constructions which contain each three Lac I regulated enterobactin synthesis genes. E. coli naturally have those genes into a single operon but due to their important lenghts, we decided to divide them into two indivudual constructions in order to make the cloning easier.

Fig 1 First construction containing the Lac I regulated enterobactin synthesis genes Ent A, Ent D and Ent F. Genes fusions were made with flanking restriction sites that are compatible with Biobrick-based cloning.


Fig 2 Second construction containing the Lac I regulated enterobactin synthesis genes Ent B, Ent C and Ent E. Genes fusions were made with flanking restriction sites that are compatible with Biobrick-based cloning.

Future caracterisation of the construction

Even though we tried to simplify the cloning, we did not succeed to obtain our two constructions.
