CC   -!- FUNCTION: This protein may be a central component in the iron-
CC       acquisition system.
CC   -!- SUBCELLULAR LOCATION: Periplasm.
CC   -!- INDUCTION: By iron deprivation.
CC   -!- MISCELLANEOUS: Iron co-purifies with FBP and is bound by the protein as
CC       a Fe(3+) ion at an approximate molar ratio of 1:1.
CC   -!- SIMILARITY: Belongs to the bacterial solute-binding protein 1 family.
CC       {ECO:0000305}.
