CC       halophilic, denitrifying bacteria.
CC   -!- BIOPHYSICOCHEMICAL PROPERTIES:
CC       Redox potential:
CC         E(0) is +323 mV.;
CC       Temperature dependence:
CC         Thermostable.;
CC   -!- SUBUNIT: Homodimer. {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the high-potential iron-sulfur protein (HiPIP)
CC       family. {ECO:0000255|PROSITE-ProRule:PRU00705}.
