report circuit

Report circuit.png

Usage and Biology

The report gene circuit consists of two periods of phage infection. In incubation period (about 5 min), there is an inducible promoter PputA((BBa_K3137002)) and a green fluorescent protein gene gfp(BBa_K3137011). In burst period (about 20 min), there is an inducible promoter PglcF(BBa_K3137003), and a red fluorescent protein gene mCherry(BBa_K3137004).

When E. coli is infected by a phage, report gene circuits are induced to express. When a phage infects E. coli into the incubation period (about 5 min), the inducible promoter PputA(BBa_K3137002) will induce the bacteria to expressthe green fluorescent protein gene gfp(BBa_K3137011).

Green fluorescence of E.coli before and after phage infection

If the resistant proteins successfully resist phage infection, the inducible promoter PglcF(BBa_K3137003) will not induce the expression of downstream gene. If the resistant proteins fail to kill phages, it means that phages will continue to infect bacteria, when it comes to the burst period (around 20 min) of phage infection, the inducible promoter PglcF(BBa_K3137003) will activate the red fluorescent protein gene mCherry. so that the bacteria will display red fluoresce and lyse cells before the assembly of phages.
