RT   ferric-pseudobactin receptor of Pseudomonas putida WCS358.";
RL   Mol. Microbiol. 8:591-601(1993).
CC   -!- FUNCTION: Specific receptor for the siderophores ferric pseudobactin
CC       BN8 and ferric pseudobactin BN7, iron chelating molecules that allow
CC       the organism to extract iron from the environment, especially under
CC       iron-restricted conditions.
CC   -!- SUBCELLULAR LOCATION: Cell outer membrane.
CC   -!- INDUCTION: By iron limitation in addition to the presence of one of the
CC       two cognate pseudobactins BN7 or BN8.
CC   -!- SIMILARITY: Belongs to the TonB-dependent receptor family.
CC       {ECO:0000305}.
