Functioni

Biosynthesis of L-glutamate from L-aspartate or L-cysteine. Important regulator of levels of glutamate, the major excitatory neurotransmitter of the vertebrate central nervous system. Acts as a scavenger of glutamate in brain neuroprotection. The aspartate aminotransferase activity is involved in hepatic glucose synthesis during development and in adipocyte glyceroneogenesis. Using L-cysteine as substrate, regulates levels of mercaptopyruvate, an important source of hydrogen sulfide. Mercaptopyruvate is converted into H2S via the action of 3-mercaptopyruvate sulfurtransferase (3MST). Hydrogen sulfide is an important synaptic modulator and neuroprotectant in the brain.

Miscellaneous

In eukaryotes there are cytoplasmic, mitochondrial and chloroplastic isozymes.

Catalytic activityi

L-aspartate + 2-oxoglutarate = oxaloacetate + L-glutamate.
L-cysteine + 2-oxoglutarate = mercaptopyruvate + L-glutamate.
