CFP Reporter under control of the c-di-AMP-dependent YdaO Riboswitch
This part is a reporter system.
It is composed of a riboswitch from Bacillus subtilis genomic DNA with its native promoter and its native RBS (BBa_K1045004), controlling the expression of cfp as a reporter gene (BBa_E0020).
Ideally, in the presence of c-di-AMP, the riboswitch leads to premature termination of cfp transcription. In the absence of c-di-AMP, the system uses the terminator present in the pSB1C3 backbone. This results in the formation of a cfp mRNA which can be translated in a functional CFP protein. Thus, in the abscence of c-di-AMP, the system should fluoresce. In the presence of c-di-AMP, however, the system should not fluoresce.
Furthermore, in combination with the diadenylate cyclase domain (BBa_K1045003), the riboswitch reporter system could indicate the state of the c-di-AMP biosynthesis. This could be exploited in order to screen substances for effects on c-di-AMP homeostasis.
