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.

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.
