General description
Glutamate-pyruvate transaminase is a blood enzyme. It metabolizes glutamate in blood resulting in low extracellular levels of brain glutamate.[1]
Application
Synthesis of unnatural L-amino acids from α-keto acids.
Physical form
Suspension in 3.2 M ammonium sulfate solution, pH approximately 6
Preparation Note
Activator: Pyridoxalphosphate
Storage conditions (working solution): The enzyme is stable when dissolved in human serum and frozen in aliquots. For best results, centrifuge the enzyme and decant the supernatant before dissolving the enzyme in human serum to avoid high ammonium sulfate concentrations in the solution.
