Cloning

Part was cloned from B. subtilis gDNA. Reaction product was analysed on an agarose gel (Figure 1)

Figure 1. Agarose gel shows a PCR product of a desired size

Functional analysis

It was assumed that over-expression of Fur could increase bacterial tolerance to increased iron concentration due to enhanced perception of environmental [iron]. This was analysed experimentally be culturing cells induced and not induced to express Fur in LB nmedium supplemented with increasing concentrations of iron. Results obtained (figure 2)indicate that indeed the cells that contain more copies of Fur protein survive better in medium with increased iron levels
