CC   -!- FUNCTION: Ferredoxins are iron-sulfur proteins that transfer electrons
CC       in a wide variety of metabolic reactions. Donates electrons to the
CC       nitrogenase.
CC   -!- COFACTOR:
CC       Name=[2Fe-2S] cluster; Xref=ChEBI:CHEBI:190135;
CC       Note=Binds 1 [2Fe-2S] cluster.;
CC   -!- SIMILARITY: Belongs to the 2Fe2S plant-type ferredoxin family.
CC       {ECO:0000305}.
