Design Notes

This switch half is in the "ON" orientation.

Design and Construction of the new natural fim switch:

Given the importance of the LRP and IHF binding sites in the switch, and the lack of these sites in the engineered fim switch we created last year, we decided to copy the natural fim switch as close as possible. The sequence of the switch varies slightly from strain to strain in E. coli. We chose to use the natural switch sequence from E. coli CFT073 because that is the strain that has the most characterization data on hbiF.
