Confirming expression of OxyR by BBa_K1104250
We conduct an SDS
Applications of BBa_K1104250
In OxyR-included circuit, Device2 is composed of sensor (OxyR-induced promoter, including TrxCp, HemHp, sufA, AhpCp1000, AhpCp2D1, AhpCp2, AhpCpD1, AhpCp1, DsbGp) plus reporter (Part:BBa_E0840). In this case we use AhpCp2D1.
 Device1 (Part:BBa_K1104250) a constitutive promoter(Part:BBa_J23102)+ RBS(Part:BBa_B0034)+ activator OxyR(Part:BBa_K1104200)+ double terminator Part:BBa_B0015 |
 Device2 a sensor (OxyR-induced promoter, including TrxCp, HemHp, sufA, AhpCp1000, AhpCp2D1, AhpCp2, AhpCpD1, AhpCp1, DsbGp) + reporter (Part:BBa_E0840) |
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:
AhpC2D1(K1104204) Device1 testing
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).
Not only for sensing the midgut oxygen stress caused by Nosemasis, in our project, there are some previous iGEM team who used OxyR-induced promoter, such as [http://2010.igem.org/Team:KIT-Kyoto/Parts 2010 KIT-Tokyo team] using it for the ink of E.coli Pen colorful. And those OxyR-induced promoters relative to the projects.
Since ROS is a natural byproduct of the metabolism and have important roles in cell signaling and homeostasis, the improvement of ROS-induced promoter is useful for sensing some specific conditions. ROS is found to involve in cancer, aging and apoptosis. Thus ROS-induced promoter in the future application can be apply to diagnosis and therapy of certain kinds of physical phenomena or disease.
