CC   -!- FUNCTION: Mnh complex is a Na(+)/H(+) antiporter involved in Na(+)
CC       excretion. {ECO:0000250}.
CC   -!- SUBUNIT: May form a heterooligomeric complex that consists of seven
CC       subunits: mnhA1, mnhB1, mnhC1, mnhD1, mnhE1, mnhF1 and mnhG1.
CC       {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000305}; Multi-pass membrane
CC       protein {ECO:0000305}.
CC   -!- SIMILARITY: Belongs to the CPA3 antiporters (TC 2.A.63) subunit B
CC       family. {ECO:0000305}.
