RFP with B. subtilis specific strong promoter R0

I. Part BBa K2666001 : Function

The Montpellier iGEM team 2018 designed a construction that produce RFP in Bacillus subtilis (http://2018.igem.org/Team:Montpellier/Toolbox). For that, we used the promoter R0, a B.subtilis specific strong promoter [1]. Figure 1 illustrates the detailed design.

Figure 1 : Construct design. The sequence that encode RFP fusionned with a strong promoter R0.

The objective is to check the strength of several construction in E.coli, L.jensenii & B.subtilis.

II. Proof of function

Figure 3 : Number of E.coli that produce RFP by low cytometer. A) E. coli population with the construction R0-RFP B) Control without plasmid.

III. Design Considerations

We added spacers to all of our constructions to unable easier use of the sequence and separation of the different genes of the sequences. We used two Terminators to our sequences :BBa_B0014 & BBa_B0015 to ensure the stopping of the transcription.
