CC   -!- FUNCTION: Involved in the recovery of exogenous heme iron. Extracts
CC       iron from heme while preserving the protoporphyrin ring intact.
CC       {ECO:0000250|UniProtKB:P31545}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2 H(+) + heme b = Fe(2+) + protoporphyrin IX;
CC         Xref=Rhea:RHEA:22584, ChEBI:CHEBI:15378, ChEBI:CHEBI:29033,
CC         ChEBI:CHEBI:57306, ChEBI:CHEBI:60344; EC=4.99.1.1;
CC         Evidence={ECO:0000250|UniProtKB:P31545};
CC       PhysiologicalDirection=left-to-right; Xref=Rhea:RHEA:22585;
CC         Evidence={ECO:0000250|UniProtKB:P31545};
CC   -!- COFACTOR:
CC       Name=heme b; Xref=ChEBI:CHEBI:60344; Evidence={ECO:0000250};
CC       Note=Binds 1 heme b (iron(II)-protoporphyrin IX) group non-covalently
CC       per subunit. {ECO:0000250};
CC   -!- SUBUNIT: Homodimer. Part of a ferrous iron transporter composed of
CC       EfeU, EfeO and EfeB (By similarity). {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Periplasm {ECO:0000250}.
CC   -!- PTM: Predicted to be exported by the Tat system. The position of the
CC       signal peptide cleavage has not been experimentally proven.
CC   -!- SIMILARITY: Belongs to the DyP-type peroxidase family. EfeB subfamily.
CC       {ECO:0000305}.
