Protein

Aspartate aminotransferase 3, chloroplastic

Gene

ASP3

Organism
Arabidopsis thaliana (Mouse-ear cress)
Status
Reviewed-Annotation score: -Experimental evidence at protein leveli

Functioni

Amino acid aminotransferase important for the metabolism of amino acids and Krebs-cycle related organic acids. No activity with D-Asp or D-Ala as amino donors. In plants, it is involved in nitrogen metabolism and in aspects of carbon and energy metabolism.2 Publications

Miscellaneous

In eukaryotes there are cytoplasmic, mitochondrial and chloroplastic isozymes.

Catalytic activityi

L-aspartate + 2-oxoglutarate = oxaloacetate + L-glutamate.2 Publications
