1. Isothermal Titration Calorimetry (ITC)
Result:
We have to cancel the ITC experiment since we did not handle enough DNA components ,that are promoters and response elements, and protein ,CooA .

2. Electrophoretic Mobility Shift Assay (EMSA)
Result:
As indicated, slight retardation in PCOOF and PCOOM bands are observed. On the other hand, it is difficult to conclude an affinity difference between these promoters based on the intensity of retarded bands.
3. Intrinsic Tryptophan Fluorescence (ITF)
Result:
pink:reduced - CO bounded CooA + buffer
yellow : reduced –CO bounded CooA + 28 nM pCooF ( 20. Min)
blue: reduced –CO bounded CooA +56 nM pCooF ( 40. Min) </br>
green: NC: reduced –CO bounded CooA + 10 ul elution buffer ( 20.min)
purple: NC: reduced – CO bounded CooA+ 20 ul elution buffer (40. Min )
As shown in the graph, there is an decrease in the intensity of the fluorescence; however when looked at negative control measurements, we saw the decrease in intensity because of the dilution and time effects. So we cannot say that the reduction is caused from pCooF – CooA interaction. Moreover, we suspect that heme group in the CooA quench fluorescence of the tryptophan and also heme group gives absorbance at 280- 400 nm so our protein might give the fluorescence at that range itself.
