The beast and its Achilles heel:

 A novel target to fight multi-resistant pathogenic bacteria

The activity of transcriptional regulators can be easily detected by monitoring the activity of a promoter that is fused to a reporter gene. Recently, in Mycobacterium smegmatis, a transcriptional repressor (DarR) was identified that is able to bind to a specific DNA sequence upon association with c-di-AMP. This led us to the idea of developing a screening system for potential drugs interfering with c-di-AMP biofunction. While many Gram-positive bacteria require c-di-AMP for their growth, this molecule is not synthesized by the Gram-negative bacterium E. coli. Thus, we intend to build a reporter system consisting of the iGEM biobricks in E. coli (Figure 1).
