Protein

Aspartate aminotransferase, mitochondrial

Gene

GOT2

Organism
Homo sapiens (Human)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Catalyzes the irreversible transamination of the L-tryptophan metabolite L-kynurenine to form kynurenic acid (KA). Plays a key role in amino acid metabolism. Important for metabolite exchange between mitochondria and cytosol. Facilitates cellular uptake of long-chain free fatty acids.1 Publication

Miscellaneous

In eukaryotes there are cytoplasmic, mitochondrial and chloroplastic isozymes.

Catalytic activityi

L-aspartate + 2-oxoglutarate = oxaloacetate + L-glutamate.1 Publication
L-kynurenine + 2-oxoglutarate = 4-(2-aminophenyl)-2,4-dioxobutanoate + L-glutamate.

Cofactori

pH dependencei

Optimum pH is 8.5.1 Publication

Temperature dependencei

Optimum temperature is 47.5 degrees Celsius.1 Publication
