RT acetivorans involves a sodium-translocating Rnf complex.";
RL FEBS J. 279:4444-4452(2012).
CC -!- FUNCTION: Part of a membrane-bound complex that couples electron
CC transfer with translocation of ions across the membrane. Catalyzes
CC Na(+) transport, most probably coupled to electron transfer from
CC reduced ferredoxin to methanophenazine and heterodisulfide reductase.
CC Involved in heterodisulfide reduction during methanogenesis from
CC acetate. {ECO:0000269|PubMed:23066798}.
CC -!- COFACTOR:
CC Name=[4Fe-4S] cluster; Xref=ChEBI:CHEBI:49883;
CC Evidence={ECO:0000255|HAMAP-Rule:MF_00461};
CC Note=Binds 2 [4Fe-4S] clusters per subunit. {ECO:0000255|HAMAP-
CC Rule:MF_00461};
CC -!- SUBUNIT: The Rnf complex is probably composed of eight subunits,
CC including RnfA, RnfB, RnfC, RnfD, RnfE and RnfG. {ECO:0000255|HAMAP-
CC Rule:MF_00461, ECO:0000305|PubMed:23066798}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000255|HAMAP-Rule:MF_00461};
CC Peripheral membrane protein {ECO:0000255|HAMAP-Rule:MF_00461}.
CC -!- DISRUPTION PHENOTYPE: Deletion of the rnf operon abolishes growth on
CC acetate and ferredoxin:heterodisulfide oxidoreductase-coupled Na(+)
CC transport. {ECO:0000269|PubMed:23066798}.
CC -!- SIMILARITY: Belongs to the 4Fe4S bacterial-type ferredoxin family. RnfC
CC subfamily. {ECO:0000255|HAMAP-Rule:MF_00461}.
