OxyR

Introduction

The Escherichia coli OxyR transcription factor senses H₂O₂ to activate transcription, and is activated through the formation of an intramolecular disulfide bond.

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.)

Literature Study of OxyR

Illustration of OxyR Activation

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.
