RT   enhances growth on malate at low protonmotive force.";
RL   J. Biol. Chem. 275:30287-30292(2000).
CC   -!- FUNCTION: Couples proton uptake and Na(+) efflux to the substrate-
CC       product malate/lactate antiport, in an electroneutral malate-
CC       2H(+)/Na(+)-lactate exchange. Plays a role in supporting growth to high
CC       density on malate at reduced protonmotive force.
CC   -!- SUBCELLULAR LOCATION: Cell membrane; Multi-pass membrane protein.
CC   -!- SIMILARITY: Belongs to the NhaC Na(+)/H(+) (TC 2.A.35) antiporter
CC       family. {ECO:0000305}.
