An alternative iron chelator
At the Regional Jamboree, we discussed with Edinburgh team which also work on iron chelation but with another chelator: the ferric ion-binding protein A (FbpA).
This protein from Neisseria gonorrhoeae is able to chelate various ion in solution as Fe3+
, Ti4+,Cu2+, Zr4+(Zirconium ion)
or Hf4+ (Hafnium ion).
Its affinity for ferrous iron is 1018, less than our enterobactins system, but it remains a good alternative for our treatment.
