Confirming expression of OxyR by BBa_K1104250

We conduct an SDS Polyacrylamide gel electrophoresis for OxyR expression.

Setting control group contains only E.coli MG1655 and experimental group with K1104250 added to AhpCp2D1(K1104204), the electrophoresis result shows OxyR (Molecular Weight of Polypeptide: 34.276 kD) can really be expressed.

Applications of BBa_K1104250

OxyR-included circuit(Device1+Device2)

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:

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.
