CC -!- FUNCTION: Mrp complex is a Na(+)/H(+) antiporter that is considered to
CC be the major Na(+) excretion system in B.subtilis. Has a major role in
CC Na(+) resistance and a minor role in Na(+)- and K(+)-dependent pH
CC homeostasis as compared to TetB. MrpA may be the actual Na(+)/H(+)
CC antiporter, although the six other Mrp proteins are all required for
CC Na(+)/H(+) antiport activity and Na(+) resistance. MrpA is required for
CC initiation of sporulation when external Na(+) concentration increases.
CC Also transports Li(+) but not K(+), Ca(2+) or Mg(2+).
CC {ECO:0000269|PubMed:10198001, ECO:0000269|PubMed:17293423}.
CC -!- SUBUNIT: Forms a heterooligomeric complex that consists of seven
CC subunits: MrpA, MrpB, MrpC, MrpD, MrpE, MrpF and MrpG.
CC {ECO:0000269|PubMed:17693497}.
CC -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Multi-pass membrane
CC protein {ECO:0000305}.
CC -!- MISCELLANEOUS: Mrp-dependent antiport apparently occurs by a secondary,
CC proton motive force-dependent mechanism, but the similarity of several
CC Mrp proteins to membrane-embedded subunits of energy-coupled NADH
CC dehydrogenase complexes raises the possibility that there is a capacity
CC for electron transport that could provide a primary energy coupling
CC option for Mrp functions.
CC -!- SIMILARITY: Belongs to the CPA3 antiporters (TC 2.A.63) subunit C
CC family. {ECO:0000305}.
