Part:BBa_K1850001
fimH
Usage and Biology
This part contains the fimH adhesin. The FimH protein is a subunit of a naturally occurring structure in some strains of E. coli called type 1 pili. These hairlike appendages typically manifest as organelles on the surface of pathogenic E. coli which are responsible for urinary tract infections in humans. The FimH adhesin is found at the tip of the pilus, and binds naturally to the sugar mannose. BBa_K1850000 contains this part under control of a titratable rhamnose promoter, and can be cotransformed with BBa_K1850013, which contains the rest of the fim operon, and then induced to produce type 1 pili.
FimH can be modified to bind to a variety of biotic and abiotic surfaces by introducing a binding peptide fusion with the desired affinity to site 225, 258 or the N terminal (recommended for folded binding motifs). These sites are highlighted in the following image orange, red and purple respectively:
Q5 PCR mutagenesis New England Biolabs was used for this purpose but other techniques may also be suitable. See our [http://2015.igem.org/Team:Harvard_BioDesign/Platform wiki] for more information.
