DESIGN CONSIDERATIONS
Promoter Coice
The ompA promoter is a constituent and strong Flavobacterial promoter. Our project's goal is the large production of structurally coloured cellulose, so a strong promoter is deemed necessary.
RBS Choice
This RBS is strong, and Flavobacteria specific.
Terminator Choice
This strong terminator sequence is chosen based on its universality and its efficient characterisation.
Assembly
The assembly method that used to create this TU is TypeIIS.
Why
We opted for this method of assembly based on many factors. For one, the scarless ligations lowered the level of uncertainty and noise on our construct. Aslo, should we be forced to order the CDS in several parts, due to its big size, we could easily ligate the parts, with no indels or stop codon insertions.
Second, a factor that contributed largely to our choice was the single-pot, single-reaction nature of the reaction. Our project, as many iGEM projects, contained a large number of assemblies, and thus such a reaction could save time, recourses and failex experiments.
How
Our ordered DNA (level 0) was flanked both on the 5' and the 3' end with specific sequences. These, among other things, contained BsaI sites whcih, upon restriction digestion would leave specific overhangs that would ensure ligation in the right order. This level 1 Transcriptional Unit would then be
