CC -!- FUNCTION: Involved in iron-sulfur cluster biogenesis. Binds a 4Fe-4S
CC cluster, can transfer this cluster to apoproteins, and thereby
CC intervenes in the maturation of Fe/S proteins. Could also act as a
CC scaffold/chaperone for damaged Fe/S proteins. {ECO:0000256|HAMAP-
CC Rule:MF_01637}.
CC -!- COFACTOR:
CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_01637};
CC Note=Binds 1 [4Fe-4S] cluster per subunit. The cluster is presumably
CC bound at the interface of two monomers. {ECO:0000256|HAMAP-
CC Rule:MF_01637};
CC -!- SUBUNIT: Homodimer. {ECO:0000256|HAMAP-Rule:MF_01637}.
CC -!- SIMILARITY: Belongs to the NfuA family. {ECO:0000256|HAMAP-
CC Rule:MF_01637}.
