OxyR
Introduction
OxyR is Escherichia coli transcription factor that senses H2O2 to activate transcription, and is activated through the formation of an intramolecular disulfide bond.
Literature Study of OxyR
OxyR, a positive regulator of hydrogen peroxide-inducible genes in E. coli. The OxyR transcription factor regulates the H2O2 response of E. coli. H2O2 oxidizes OxyR Cys199 to an R-SOH that reacts with Cys208 in an intramolecular disulphide bond.

Usage and Biology
After Nosema ceranae enter bees' midgut, the natural immune reaction will lead to ROS released by epithelia of bees' midgut. In our project: Bee. coli, we use OxyR-induced promoter as the sensor of Bee. coli to sense Nosema ceranae. We select several promoters that can be induced by OxyR(Part:BBa_K1104200).
There are promoters that can be activated by OxyR: TrxCp(Part:BBa_K1104201), HemHp(Part:BBa_K1104202), ahpC(Part:BBa_K362001), sufA(Part:BBa_K362005).
The OxyR-induced promoters:
- TrxCp(Part:BBa_K1104201) and HemHp(Part:BBa_K1104202) are parts created by our team [http://2013.igem.org/Team:NYMU-Taipei/Modeling/MainParts NYMU_Taipei].(Come to the [http://2013.igem.org/Team:NYMU-Taipei/Experiment/Wet_Lab Wet Lab] page to see our part list.)
- sufA(Part:BBa_K362005), designed by [http://2010.igem.org/Team:KIT-Kyoto/Parts 2010 KIT-Tokyo team], is successfully characterized again by us.
- ahpC(Part:BBa_K362001) is improved its complex composition and Assembly Compatibility by us. We designed ahpC(Part:BBa_K362001) improvement into 6 versions:
- AhpCp1000(Part:BBa_K1104203)
- AhpCp2D1(Part:BBa_K1104204)
- AhpCp2(Part:BBa_K1104205)
- AhpCpD1(Part:BBa_K1104206)
- AhpCp1(Part:BBa_K1104207)
- DsbGp(Part:BBa_K1104208)
