2.A.29.2.1
Oxoglutarate/malate antiporter. Also transports porphyrin derivatives: Fe-protoporphyrin IX, coproporphyrin III, hemin, etc. (Kabe et al., 2006). Plays roles in the malate-aspartate shuttle, the oxoglutarate-isocitrate shuttle and gluconeogenesis.  Functional residues have been identified (Cappello et al. 2007).
