The beast and its Achilles heel:

 A novel target to fight multi-resistant pathogenic bacteria



Reporter Team

The activity of transcriptional regulators can be easily monitored by expressing a reporter gene downstream of a promoter, containing their binding site. 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).
