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
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)
