Protein

Aspartate aminotransferase, mitochondrial

Gene

aatA

Organism
Dictyostelium discoideum (Slime mold)
Status
Reviewed-Annotation score: -Protein inferred from homologyi

Functioni

Plays a key role in amino acid metabolism. Important for metabolite exchange between mitochondria and cytosol (By similarity).By similarity

Miscellaneous

In eukaryotes there are cytoplasmic, mitochondrial and chloroplastic isozymes.

Catalytic activityi

L-aspartate + 2-oxoglutarate = oxaloacetate + L-glutamate.
L-kynurenine + 2-oxoglutarate = 4-(2-aminophenyl)-2,4-dioxobutanoate + L-glutamate.
