D-threo-isocitrate(in) + citrate(out) = D-threo-isocitrate(out) + citrate(in)
d-threo-isocitrate(in) + citrate(out) = d-threo-isocitrate(out) + citrate(in)
D-threo-isocitrate(in) + citrate(out) = D-threo-isocitrate(out) + citrate(in)
d-threo-isocitrate(in) + citrate(out) = d-threo-isocitrate(out) + citrate(in)
