CC   -!- FUNCTION: May bind free porphyrinogens that may be present in the cell
CC       and thus facilitate removal of these potentially toxic compound. Binds
CC       with a high affinity to one molecule of heme or porphyrins. It binds
CC       metalloporphyrins, free porphyrins and N-methylprotoporphyrin with
CC       similar affinities (By similarity). {ECO:0000250}.
CC   -!- SUBUNIT: Monomer. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cytoplasm {ECO:0000250}.
CC   -!- DOMAIN: Forms a distorted beta-barrel structure, with two helices that
CC       are packed against the outer surface of the barrel. Porphyrins are
CC       expected to bind to a hydrophobic patch on the outer surface of the
CC       beta-barrel structure (By similarity). {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the HEBP family. {ECO:0000305}.
