Engineered FliC with insertable expression region

The FliC gene codes for flagellin, a protein that arranges itself in a hollow cylinder to form the filament of a bacterial flagellum. The N and C termini of flagellin and alpha-helices flanking the termini form the inner core of the filament cylinder (Bergman). The central portion, or “dispensable region,” forms the outer surface of the filament, and is highly variable.

iGEM Team Slovenia 2008 used the FliC gene to design a chimeric fusion protein expressing the antigenic segment of H. pylori on E. coli flagella (BBa_K133038). Our team wanted to use the same flagellar expression mechanism to express metal binding sequences, and our part is an improvement on the Slovenian biobrick. In the process, we designed the FliC gene with a multiple cloning site (MCS) in the dispensable region so that any iGEM team can insert a protein to be expressed in the dispensable region.

MCS has the following restriction sites: BamHI, AvaII, BglII, HindIII, NdeI, PvuI, SphI, Xmal, SalI
