CC   -!- FUNCTION: Rubredoxin is a small nonheme, iron protein lacking acid-
CC       labile sulfide. Its single Fe, chelated to 4 Cys, functions as an
CC       electron acceptor and may also stabilize the conformation of the
CC       molecule.
CC   -!- COFACTOR:
CC       Name=Fe(3+); Xref=ChEBI:CHEBI:29034; Evidence={ECO:0000250};
CC       Note=Binds 1 Fe(3+) ion per subunit. {ECO:0000250};
CC   -!- SIMILARITY: Belongs to the rubredoxin family. {ECO:0000305}.
