CC -!- FUNCTION: Part of a membrane-bound complex that couples electron
CC transfer with translocation of ions across the membrane. Required to
CC maintain the reduced state of SoxR. {ECO:0000255|HAMAP-Rule:MF_00463}.
CC -!- COFACTOR:
CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00463};
CC Note=Binds 3 [4Fe-4S] clusters. {ECO:0000255|HAMAP-Rule:MF_00463};
CC -!- SUBUNIT: The complex is composed of six subunits: RsxA, RsxB, RsxC,
CC RsxD, RsxE and RsxG. {ECO:0000255|HAMAP-Rule:MF_00463}.
CC -!- SUBCELLULAR LOCATION: Cell inner membrane {ECO:0000255|HAMAP-
CC Rule:MF_00463}.
CC -!- SIMILARITY: Belongs to the 4Fe4S bacterial-type ferredoxin family. RnfB
CC subfamily. {ECO:0000255|HAMAP-Rule:MF_00463}.
