Part:BBa_K777109

fliC

• The fliC gene codes for flagellin. This protein is the subunit that forms the flagellar filament of E. coli.

Usage and Biology

Fig. 1: BL21 E. coli carrying different constructs on [http://2012.igem.org/Team:Goettingen/Project/Materials#Tryptone_swimming_agar tryptone swimming agar] after 12h incubation at 33°C. Cells expressing fliC in puc18 under the natural promoter travelled approximately 0.25cm (radius) whereas no swimming could be detected for the control plasmid carrying K777125. On tryptone swimming agar yhjH transformants were usually faster.

We expected that transformation of E. coli with fliC constructs would results in longer flagella filaments. Unfortunately we were not able to confirm this via transmission electron microscopy. However we tested the transformed strains in swimming agar assays and they were significantly faster than control strains (Fig. 1). This was the case on [http://2012.igem.org/Team:Goettingen/Project/Materials#M9_Swimming_Agar M9 minimal medium swarming agar] and also on [http://2012.igem.org/Team:Goettingen/Project/Materials#Tryptone_swimming_agar tryptone swimming agar]. This indicates that fliC transformation indeed caused longer flagella filaments and thus higher motility in BL21 E. coli.
