Design Notes

Insertion of the FUR box was informed by the report by Chu et al., (2015). This study inserted the FUR box region at different locations on a plasmid containing the LuxR/LuxI QS system. The construct with the insert at the -10 region (termed ironQS2) performed the best in experiments testing different constructs (as seen below) in low iron environments.

IronQS2 with the FUR box located at -10 position performed well at suppressing genes in low iron environments (in presence of iron chelator 2-2' Bipyridine)
