Design Notes
To make the fliC biobrick, fliC was amplified by PCR using the proofreading Phusion polymerase with DS941 genomic DNA as template. The forward primer incorporated the prefix and added the BBa_B0034 ribosome binding site (RBS) and a scar sequence just upstream of fliC. The reverse primer incorporated the suffix and removed one undesirable PstI restriction site in fliC.
We sequenced our fliC biobrick and found that it had the expected sequence, identical to fliC of the sequenced E. coli strain MG1655 at all positions except for the changes we had made to remove three PstI sites and one SpeI site. However, there were two coding differences between our biobrick and a previous fliC biobrick in the parts registry K777109. These differences are due to different source strains (We used MG1655 genomic DNA, they used E. coli strain K-12 substr. DH10B). It is unclear if these nonsynonymous changes alter flagella formation.
