CC   -!- FUNCTION: Catalyzes the irreversible transamination of the L-tryptophan
CC       metabolite L-kynurenine to form kynurenic acid (KA). As a member of the
CC       malate-aspartate shuttle, it has a key role in the intracellular NAD(H)
CC       redox balance. Is important for metabolite exchange between
CC       mitochondria and cytosol, and for amino acid metabolism. Facilitates
CC       cellular uptake of long-chain free fatty acids.
CC       {ECO:0000250|UniProtKB:P00505}.
CC   -!- CATALYTIC ACTIVITY:
CC       Reaction=2-oxoglutarate + L-aspartate = L-glutamate + oxaloacetate;

CC         Evidence={ECO:0000250};
CC   -!- SUBUNIT: Homodimer. {ECO:0000250}.
CC   -!- SUBCELLULAR LOCATION: Mitochondrion matrix {ECO:0000250}. Cell membrane
CC       {ECO:0000250}.
CC   -!- MISCELLANEOUS: In eukaryotes there are cytoplasmic, mitochondrial and
CC       chloroplastic isozymes.
CC   -!- SIMILARITY: Belongs to the class-I pyridoxal-phosphate-dependent
CC       aminotransferase family. {ECO:0000305}.
