FimH+ MouseMT

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.

FimH is an the terminal protein of a bacterial type I pilus structure. As an adhesin, it binds mannose in nature. This part produces a FimH adhesin protein fused with a metallothionein from Mus musculus (Huang et al 1981) at the first amino acid position, 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 a number of heavy metal ions. This part is included in the composite part https://parts.igem.org/Part:BBa_K2324010 under the pRha promoter.
