This is the relative promoter strength of BBa_K1104204 under different H202 concentrations tested using BBa_K1104244 (BBa_K1104204 +E0840) and found that there is a trend where the higher the H202 concentration, the higher the promoter expression:
Strengths of the basal level of various promoters that respond to reactive oxygen species with respect to BBa_J23101, and the AhpC2D1 promoter shows higher strength than the AhpCp 1000 which is an effective improvement :
Promoter testing of ahpC promoter (Part:K362001) and its improvements.
Device1 in order to enhance the effect of ROS on E. coli is added ahead: a constitutive promoter(Part:BBa_J23102), RBS(Part:BBa_B0034), activator OxyR(Part:BBa_K1104200),and double terminator Part:BBa_B0015. Putting Device1 device:BBa_K1104250 upstream to promoter AhpCp2D1(Part:BBa_K1104204) remarkably enhanced the strength of promoter AhpCp2D1(Part:BBa_K1104204) as our experiment results shows:
