PputA              50bp inducible promoter
PputA is the inducible promoter that When E.coli is infected by a phage, both report and respond gene circuits are induced to express at the same time. When a phage infects Escherichia coli into the incubation period (about 5 min), PputA will induce the bacteria to express resistant protein and display green fluorescence.

PglcF               50bp inducible promoter
PglcF is the inducible promoter that works when phages infect bacterial for around 20 min. If the resistant proteins successfully resist phage infection, the inducible promoter PglcF will not induce the expression of downstream gene. If the resistant proteins cannot kill phages, the phages will continue to infect. When phages infect bacteria into the outbreak period (about 20 min), the inducible promoter PglcF will induce expression of the red fluorescent protein gene mCherry and the downstream toxic protein gene protegrin-1, which will make the bacteria display red fluorescence and lyse cells before the assembly of phages.

gntR              996bp
The Gluconate repressor gntR, is a transcription factor that negatively regulates the operon involved in the catabolism of d-gluconate via the Entner-Doudoroff pathway and represses genes involved in the different systems related to d-gluconate uptake: gluconate I and gluconate II.

abpAB              3803bp resistant protein
AbpAB are two genes of the E.coli genome that express resistant proteins that are resistant to T2,T4,T7 and λ phages. We obtained abpA and abpB by PCR from the genome of ?E.coli BL21 and constructed recombinant plasmid that connected abpA and abpB at the same time, then used IPTG to induce the expression of resistant protein and verified the resistant function of the protein.

codes forprotegrin-1              (anti-microbial peptide) 60bp
antibacterial peptides
Protegrin-1 coding region. Protegrin-1 is an '18-residue beta-sheet peptide isolated from porcine leukocytes with antimicrobial activity against a broad range of microorganisms.' It has its effect by pore membrane disruption and possibly also by effects such as activation of membrane-damaging proteases and has anti-microbial activity against E. coli.

report circuit     1666bp
The report gene circuit consists of two periods of phage infection. In incubation period (about 5 min),
there is an inducible promoter PputA and a green fluorescent protein gene gfp. In outbreak
period (about
20 min), there is an inducible promoter PglcF, and a red fluorescent protein gene mCherry.
When E. coli is infected by a phage, both report and respond gene circuits are induced to express
at the
same time. When a phage infects E. coli into the incubation period (about 5 min), the inducible
promoter
PputA will induce the bacteria to express the resistant protein and the green fluorescent protein
gene
gfp.
If the resistant protein successfully resists phage infection, the inducible promoter PglcF will
not
induce the expression of downstream gene. If the resistant protein fails to kill phages, it means that
phages will continue to infect bacteria, when it comes to the outbreak period (around 20 min) of phage
infection, the inducible promoter PglcF will activate the red fluorescent protein gene
mCherry and the
expression of downstream toxic protein gene so that the bacteria will display red fluoresce and lyse
cells before the assembly of phages.
BBa_K3137014
respond circuit     5097bp
The respond gene circuit is composed of an inducible promoter PputA and anti-phage protein genes of the
incubation period (about 5 min), and an inducible promoter PglcF and a toxic protein gene protegrin-1 of
the outbreak period (about 20 min).
When E. coli is infected by a phage, both report and respond gene circuits are induced to express at the
same time. When a phage infects E. coli into the incubation period (about 5 min), the inducible promoter
PputA will induce the bacteria to express the resistant protein abpAB and gntR, and the green
fluorescent protein gene gfp.
If the resistant proteins successfully resist phage infection, the inducible promoter PglcF 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 outbreak period (around 20 min) of phage
infection, the inducible promoter PglcF will activate the red fluorescent protein gene mCherry and the
expression of downstream toxic protein gene protegrin-1 so that the bacteria will display red fluoresce
and lyse cells before the assembly of phages.
