General description

Glutamate-pyruvate transaminase is a blood enzyme. It metabolizes glutamate in blood resulting in low extracellular levels of brain glutamate.

Application

Synthesis of unnatural L-amino acids from α-keto acids.

Quality

Contaminants: < 0.01% GIDH, LDH, and MDH each, < 0.03% GOT

Unit Definition

Unit Conversion: 1 U [+25 °C, pH 7.5] ≈ 1.75 U [+37 °C, pH 7.5]

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.

Other Notes

For life science research only. Not for use in diagnostic procedures.

Ischaemic stroke is associated with an excessive release of glutamate in brain. GOT (glutamate-oxaloacetate transaminase) and GPT (glutamate-pyruvate transaminase) are two enzymes that are able to metabolize blood glutamate facilitating the lowering of extracellular levels of brain glutamate. Our aim

Our team of scientists has experience in all areas of research including Life Science, Material Science, Chemical Synthesis, Chromatography, Analytical and many others.
