CC   -!- FUNCTION: This protein is involved in the initial step of iron uptake
CC       by binding hemin, an iron chelatin siderophore that allows the bacteria
CC       to extract iron from the environment.
CC   -!- SUBCELLULAR LOCATION: Cell outer membrane.
CC   -!- SIMILARITY: Belongs to the TonB-dependent receptor family.
CC       {ECO:0000305}.
