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:0000255|HAMAP-
CC       Rule:MF_01637}.
CC   -!- COFACTOR:
CC       Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC         Evidence={ECO:0000255|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:0000255|HAMAP-
CC       Rule:MF_01637};
CC   -!- SUBUNIT: Homodimer. {ECO:0000255|HAMAP-Rule:MF_01637}.
CC   -!- SIMILARITY: Belongs to the NfuA family. {ECO:0000255|HAMAP-
CC       Rule:MF_01637}.
