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};
