Part:BBa_K1463604
FliC with RBS and J23100 promoter
FliC with B0032 and B0034 RBS under the control of J23100 promoter.
This composite part was made by inserting a synthesised double-stranded oligonucleotide containing J23100 promoter (strong) and B0032 into K1463601 (fliC and B0034 RBS).
As shown in Figure 1D, this construct failed to restore swimming in knockout fliC strains. On sequencing we found this plasmid to have a mutation in the promoter, explaining this result. We failed to clone a functional J23100 promoter in front of the fliC biobrick, suggesting that strong over expression of fliC may be toxic.
