CC -!- FUNCTION: Part of a membrane-bound complex that couples electron
CC transfer with translocation of ions across the membrane.
CC {ECO:0000256|HAMAP-Rule:MF_00463}.
CC -!- COFACTOR:
CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC Evidence={ECO:0000256|HAMAP-Rule:MF_00463};
CC Note=Binds 3 [4Fe-4S] clusters. {ECO:0000256|HAMAP-Rule:MF_00463};
CC -!- SUBUNIT: The complex is composed of six subunits: RnfA, RnfB, RnfC,
CC RnfD, RnfE and RnfG. {ECO:0000256|HAMAP-Rule:MF_00463}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000256|HAMAP-Rule:MF_00463}.
CC -!- SIMILARITY: Belongs to the 4Fe4S bacterial-type ferredoxin family. RnfB
CC subfamily. {ECO:0000256|HAMAP-Rule:MF_00463}.
CC -!- CAUTION: Lacks conserved residue(s) required for the propagation of
CC feature annotation. {ECO:0000256|HAMAP-Rule:MF_00463}.
CC -!- CAUTION: The sequence shown here is derived from an EMBL/GenBank/DDBJ
CC whole genome shotgun (WGS) entry which is preliminary data.
