Function

function

Transports dicarboxylates across the inner membranes of mitochondria by a counter-exchange mechanism. Can transport 2-oxoadipate (2-oxohexanedioate), 2-oxoglutarate, adipate (hexanedioate), glutarate, and to a lesser extent, pimelate (heptanedioate), 2-oxopimelate (2-oxoheptanedioate), 2-aminoadipate (2-aminohexanedioate), oxaloacetate, and citrate. Plays a central role in catabolism of lysine, hydroxylysine, and tryptophan, by transporting common metabolite intermediates (such as 2-oxoadipate) into the mitochondria, where it is converted into acetyl-CoA and can enter the citric acid (TCA) cycle.

Catalytic activity

  • 2-oxoadipate(in) + 2-oxoglutarate(out) = 2-oxoadipate(out) + 2-oxoglutarate(in)
  • 2-oxoheptanedioate(in) + 2-oxoglutarate(out) = 2-oxoheptanedioate(out) + 2-oxoglutarate(in)
  • L-2-aminoadipate(in) + 2-oxoglutarate(out) = L-2-aminoadipate(out) + 2-oxoglutarate(in)
  • citrate(in) + 2-oxoglutarate(out) = citrate(out) + 2-oxoglutarate(in)
  • glutarate(in) + 2-oxoglutarate(out) = glutarate(out) + 2-oxoglutarate(in)
  • heptanedioate(in) + 2-oxoglutarate(out) = heptanedioate(out) + 2-oxoglutarate(in)
  • hexanedioate(in) + 2-oxoglutarate(out) = hexanedioate(out) + 2-oxoglutarate(in)
