Part:BBa_K1951008:Design

BBa_K1951008 design Not understood High flagellin expression coding sequence has been designed using two parts :

== 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. 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. 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.
