RT   ferredoxin:NAD+ oxidoreductase essential for autotrophic growth.";
RL   MBio 4:E00406-E00412(2012).
CC   -!- FUNCTION: Part of a membrane-bound complex that couples electron
CC       transfer with translocation of ions across the membrane. Couples
CC       electron transfer from reduced ferredoxin to NAD(+) with translocation
CC       of H(+) out of the cell. Essential for energy conservation during
CC       autotrophic growth. Contributes to ATP synthesis during heterotrophic
CC       growth. {ECO:0000269|PubMed:23269825}.
CC   -!- SUBUNIT: The complex is composed of six subunits: RnfA, RnfB, RnfC,
CC       RnfD, RnfE and RnfG. {ECO:0000255|HAMAP-Rule:MF_00459}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000255|HAMAP-Rule:MF_00459};
CC       Multi-pass membrane protein {ECO:0000255|HAMAP-Rule:MF_00459}.
CC   -!- SIMILARITY: Belongs to the NqrDE/RnfAE family. {ECO:0000255|HAMAP-
CC       Rule:MF_00459}.
