RT   hydroxycarboxylate transporter family that transports L-malate and
RT   citrate.";
RL   J. Bacteriol. 183:5862-5869(2001).
CC   -!- FUNCTION: Proton motive force-driven secondary transporter that
CC       catalyzes the uptake of both citrate and malate. Appears to be an
CC       electroneutral proton-solute symporter; the number of protons
CC       transported is equal to the valence of the transported anions. Is
CC       strictly stereoselective, translocating only the (S)-enantiomer of
CC       malate.
CC   -!- ACTIVITY REGULATION: The uptake activity is inhibited by divalent metal
CC       ions such as Ca(2+), Mg(2+) and Ni(2+).
CC   -!- SUBCELLULAR LOCATION: Cell membrane {ECO:0000250}; Multi-pass membrane
CC       protein {ECO:0000250}.
CC   -!- SIMILARITY: Belongs to the sodium:citrate (SCF) symporter family.
CC       {ECO:0000305}.
