RT   "Primary structure of a high potential, four-iron-sulfur ferredoxin from
RT   the photosynthetic bacterium Rhodospirillum tenue.";
RL   J. Biol. Chem. 254:1495-1500(1979).
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.
CC   -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC       Redox potential:
CC         E(0) is +330 mV.;
CC   -!- SUBUNIT: Homodimer. {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the high-potential iron-sulfur protein (HiPIP)
CC       family. {ECO:0000255|PROSITE-ProRule:PRU00705}.
