FimH+SynMT
The literature has shown that the terminal pili protein FimH (Le Trong et al 2010) can be modified by inserting heterologous sequences at position 225 and 258 (Pallesen et al 1995, Shembri et al 1999). However these two amino acids are in the pilin binding domain which may present difficulties when attempting to introduce large modifications. Harvard iGEM 2015 also introduced modifications at position 1 of the mature FimH protein.
This part codes for a FimH adhesin fused with a metallothionein protein from Synechococcus elongatus (Huang et al 1981) at amino acid residue 1, after signal peptide cleavage. It is designed to be placed on the end of a type 1 pilus structure in E. coli with a view to binding copper ions. This part is included in the composite part https://parts.igem.org/Part:BBa_K2324009 under the pRha promoter.
