CC   -!- FUNCTION: Specific class of high-redox-potential 4Fe-4S ferredoxins.
CC       Functions in anaerobic electron transport in most purple and in some
CC       other photosynthetic bacteria and in at least one genus (Paracoccus) of
CC       halophilic, denitrifying bacteria. {ECO:0000250|UniProtKB:P00260,
CC       ECO:0000255|PROSITE-ProRule:PRU00705}.
CC   -!- SUBUNIT: Homodimer. {ECO:0000250|UniProtKB:P59860}.
CC   -!- SUBCELLULAR LOCATION: Periplasm {ECO:0000250|UniProtKB:P00260,
CC       ECO:0000255|PROSITE-ProRule:PRU00705}.
CC   -!- SIMILARITY: Belongs to the high-potential iron-sulfur protein (HiPIP)
CC       family. {ECO:0000255|PROSITE-ProRule:PRU00705}.
