BBa_K1951008 design Not understood High flagellin expression coding sequence has been designed using two parts :
- design BBa_K880005 Strong promoter, strong RBS combination for high expression levels of proteins (composed of sub-parts design BBa_J23100 and design BBa_B0034
- BBa_K1951005 the FliC coding sequence designed by our team

Optimization
Sequence optimization
We took fliC sequence from Glasgow 2014 team BBa_K1463601. We used Snapgene to remove the forbidden site by changing in the substitution which didn't change the amino acid. The sequence has been sythetised by IDT[1]. We changed a Bbs1 site 130 position by substitution of amino acid coding.
Codon optimization for Escherichia coli.
We obtimised codon for Escherichia coli. Codon optimization is a technique used to improve the protein expression in living organism by increasing the translational efficiency of gene of interest [1-4, 6-13, 15-18, 20-28]. This biobrick codon optimised increase the functionality of gene. To process it, we use codon optimization IDT software[2]. If you use this biobrick in Escherichia coli, you can be sure that the protein produced will be highly expressed and well solubilised.
Prefix and suffix addition
Prefix and suffix subsequences (containing restriction site EcoRI, XbaI and SpeI PstI respectively) have been added by a SLIC method with the following oligos :
| FliC E. coli slic forward | cgctaaggatgatttctgGAATTCGCGGCCGCTTCTAGATGGCACAAGTCATTAAT |
| FliC E.coli slic reverse | ttgcccttttttgccggaCTGCAGCGGCCGCTACTAGTATTATTAACCCTGGAGCAG |

Design Notes
On the BbaK1951004, the restriction site Bbs1 is mutated (substitution) to allow the control for a future Bbs1 site insertion.
