Activity measured as a test of liver function, human Glutamic-Pyruvate Transaminases (Alanine Aminotransferase Family) are pyridoxal phosphate-dependent enzymes involved in cellular nitrogen metabolism, amino acid metabolism, and liver gluconeogenesis. Glutamic Pyruvic Transaminases mediate conversion of major intermediate metabolites, catalyzing reversible transamination between alanine and alpha-ketoglutarate to form pyruvate and glutamate. (NCI)
