AhpCp1000

Introduction

We improve the function of a BioBrick Part: ahpC promoter (Part:K362001) designed by [http://2010.igem.org/Team:KIT-Kyoto/Parts 2010 KIT-Tokyo team] into 6 versions.On PartRegistry, the complex part(according to [http://ecocyc.org/ECOLI/new-image?object=EG11384 Ecocyc]) composition contains hybrid promoters, shared TFBS (Transcription Factor Binding Site), and reverse promoter DsbG. In this part AhpCp1000, we succesfully mutated the Pst1 site (ctgcag->ctacag) of ahpC promoter (Part:K362001).

Mutation of ahpC promoter(Part:K362001)

ahpC promoter, as well as its improvement, can be activated by OxyR (Part:BBa_K1104200).

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.

Structure of the OxyR Regulatory Domain
(A)Reduced Form: Inactive
(B)Oxidized Form: Activated by ROS

Usage and Biology

We designed circuit fighting against Nosema ceranae. After Nosema ceranae infected midgut cells of bees, and Bee. coli should sense the pathogen first before the following circuit(fighting against Nosema ceranae)is triggered, and substance such as Defensin (Part:BBa_K1104300), Abaesin(Part:BBa_K1104301) (more details on [http://2013.igem.org/Team:NYMU-Taipei/Project/Inhibition/Killing Killing Nosema] page) in the following circuit will express.

To enhance the strength , we added a device (more details on [http://2013.igem.org/Team:NYMU-Taipei/Project/Inhibition/Sensor Sensing Nosema] page).
