Identification and purification of the aspartate/glutamate carrier from bovine heart mitochondria

The aspartate/glutamate carrier from bovine heart mitochondria was solubilized with dodecyl-octaoxyethylene ether (C12E8) and purified by chromatography on hydroxyapatite and celite. On SDS gel electrophoresis, the purified aspartate/glutamate carrier consisted of a single protein band with an apparent Mr of 31,500. When reconstituted into liposomes the aspartate/glutamate carrier protein catalyzed an N-ethylmaleimide-sensitive aspartate/aspartate exchange. It was purified 620-fold with a recovery of 17.2% and a protein yield of 0.03% with respect to the mitochondrial extract. The properties of the reconstituted carrier, i.e. requirement for a counteranion, substrate specificity and inhibitor sensitivity, were similar to those of the aspartate/glutamate carrier as characterized in mitochondria.
