CC   -!- FUNCTION: Could be required for the formation of a functional
CC       nitrogenase Fe protein. Probably accepts electrons from FixA/FixB and
CC       reduces a quinone.
CC   -!- COFACTOR:
CC       Name=FAD; Xref=ChEBI:CHEBI:57692; Evidence={ECO:0000305};
CC   -!- SIMILARITY: Belongs to the ETF-QO/FixC family. {ECO:0000305}.
