PBAD-rbs-mazF
Characterize
We performed experiment to work final genetic circuits.
This experiment consists of the four parts below.
Ⅰ.Adjustment of MazF Expression
Ⅱ.mazEF System Assay ~Stop & GO~
Ⅲ.mazEF System Assay ~Go & Stop~
Ⅳ.Control of Cell Growth
Ⅰ.Adjustment of MazF Expression
In order to control the TA system well, it is necessary to adjust the expression of MazF as a toxin. It has been reported that MazF has very strong ability to inhibit cell growth, and antitoxins cannot recover it under overexpression of MazF. Therefore, we explored the conditions that can control the TA system by adjusting the expression of MazF.
result
It was found that the cell growth is inhibited when the concentration of arabinose, the inducer of MazF, is more than 0.02%. However, when arabinose concentration is 0.2%, GFP fluorescence intensity falls markedly(Fig. 1.).
