''Bacillus Subtilis'' 168 strain
Encodes a stable non-specific ribonuclease in ''Bacillus Subtilis''. It is used in conjungtion with ''mazE'' in ''Bacillus Subtilis'' to provide a toxin-antitoxin in various stressful conditions. When transcribtion of both genes is turned off (as both are under contol of same promoter) ''mazE'' will be degraded faster than ''mazF''. There is then no inhibiton of ''mazF'', killing the cell.

<P> <P>Suggested by Sri Kosuri and Drew Endy as a high efficiency terminator. The 5' end cutoff was placed immediately after the TAA stop codon and the 3' end cutoff was placed just prior to the RBS of Gene 1.4 (before AAGGAG).<P> Use anywhere transcription should be stopped when the gene of interest is upstream of this terminator.

We plan to establish a new E.Coli strain without lacI and MazEF system gene to avoid the inference of cell itself. We will test cI background expression level to see if we need to knock out cI.
As is shown in Fig.1, Fig.2, Fig.3 and Fig.4, in the ???Stable State???, before poured into the soil, the E. Coli fertilizer is cultured in the medium with IPTG. Promoter 1 is a weak constitutive promoter, so lacI is transcribed and translated at a considerate low level. Therefore, high concentration of IPTG, which binds LacI and changes LacI???s conformation, is able to inactive LacI and open the promoter 2. Then, CI can be highly expressed to repress promoter3. Finally, mazF is inhibited.
After fertilizing, no more IPTG exists in the soil to bind LacI. As a result, LacI with a tag which stabilize the protein takes time to accumulate to a certain high concentration, which is the repression threshold of promoter 2, aiming to represses promoter 2 as well as the expression of cI. The time needed to finish this progress is the designed ???memory time???. During this process, E. coli takes its own responsibility to deliver Mo. And after that, it can be killed to reduce the pollution to environment.
As is shown in table 1, all the biobricks in the design are from the top 10 most used parts of iGEM to guarantee the feasibility.

Promoter 3 BBa-R0051 CI repressible promoter
Table 1 Biobricks used in the design
In the future, we plan to model the ???memory time??? and do more wet-experiments to confirm its feasibility. As for the modeling, we will test the expression level of promoter 1, the minimal stand of LacI to repress promoter 2 and the degradation speed of LacI. On the other hand, we will test the background expression of CI after removing IPTG to check if the CI concentration is low enough to open the promoter 3. Then we will strive to make this system more effective.

Inverting regulatory region controlled by LacI (<bb_part>BBa_C0010</bb_part>, <bb_part>BBa_C0011</bb_part>, etc.) <p> The pLac regulatory region is a 243 base-pair sequence with standard BioBrick prefix and suffix sections on its ends. It contains two protein binding sites: CAP, which is generally present in E.coli and is assocciated with cell health and availability of glucose., and LacI, the Lac inhibitor <bb_part>BBa_C0010</bb_part> which binds in an dimerized cooperative manner to inhibit the transcription of the protein that follows. In the presence of lactose or IPTG, an analog of lactose, LacI is unable to correctly bind and inhibit transcription. This allows <bb_part>BBa_R0010</bb_part> to be used as a inverter or as a detector of lactose or IPTG.
