RT   "Catalytic properties of Staphylococcus aureus and Bacillus members of the

CC   -!- FUNCTION: Expression of the mnh2 operon in E.coli is not able to
CC       catalyze Na(+)Li(+)/H(+) antiport. It does however confer higher growth
CC       rates than the control strain at up to pH 9.5. The operon may encode an
CC       NADH-ubiquinone oxidoreductase.
CC   -!- SUBUNIT: May form a heterooligomeric complex that consists of seven
CC       subunits: mnhA2, mnhB2, mnhC2, mnhD2, mnhE2, mnhF2 and mnhG2.
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 A
CC       family. {ECO:0000305}.
