Design Notes

We selected a rhamnose-inducible promoter (BBa_K902065) with a strong ribosome binding site (BBa_B0034), since this promoter is titratable and would allow for controlled expression of the fimH adhesin.

We edited out an illegal PstI cut site in fimH through site-directed mutagenesis.

The SpyTag binding motif was inserted into the fusion site of fimH via site-directed mutagenesis.

The nickel binding HisTag was inserted into fusion sites of fimH via site-directed mutagenesis.

We picked sites 225 and 258 since there was strong evidence in the literature that small fusions inserted at these sites such as his-tags were expressed and functional on assembled pili.
