PkatG


Description


PkatG is the promoter of the katG gene. KatG protein has the function of bifunctional hydroperoxidase I (HPI) and plays an important role in oxidative stress response. The katG promoter (PkatG) is stimulated by oxidative stress, leading to the expression of the downstream gene. Besides, PkatG is activated by OxyR protein[1].

Usage and Biology


After conducting colony PCR from the E. coli MG1655, the PkatG fragment can be amplified from the chromosome and the experiment result can be checked by agarose gel electrophoresis. The result is shown in Figure 2.
