Mitochondrial GOT2 (glutamate oxaloacetate transaminase 2, also known as aspartate aminotransferase, mitochondrial) catalyzes the reversible transamination of oxaloacetate (OAA) and glutamate (L-Glu) to form aspartate (L-Asp) and 2-oxoglutarate (2-OG, alpha-ketoglutarate) (Martini et al. 1985; van Karnebeek et al. 2019). The active form of the enzyme is a homodimer of GOT2 monomers each conjugated with pyridoxal phosphate on lysine residue 279.
