CC Evidence={ECO:0000256|ARBA:ARBA00001122,
CC ECO:0000256|PIRNR:PIRNR000159};
CC -!- COFACTOR:
CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC Evidence={ECO:0000256|PIRSR:PIRSR000159-50};
CC Note=Binds 3 [4Fe-4S] clusters per subunit.
CC {ECO:0000256|PIRSR:PIRSR000159-50};
CC -!- SIMILARITY: Belongs to the pyruvate:ferredoxin/flavodoxin
CC oxidoreductase family. {ECO:0000256|ARBA:ARBA00009032,
CC ECO:0000256|PIRNR:PIRNR000159}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
