**Definition:** A family of pyridoxal phosphate-dependent enzymes involved in cellular nitrogen metabolism, amino acid metabolism, and liver gluconeogenesis. Alanine aminotransferase specifically and reversibly catalyzes the transfer of an amino group from L-alanine to alpha-ketoglutarate forming pyruvate and L-glutamate.
