General description
Glutamic-pyruvic transaminase (GPT) is localized majorly in the liver.
Research area: Cell Signaling
Biochem/physiol Actions
Glutamic-pyruvic transaminase (GPT) is located in most cells in the body, but is found in highest concentrations in the liver. It is used as a marker of liver disease due to the release of GPT into the blood following liver cell necrosis.
Glutamic-pyruvic transaminase (GPT) mediates the transfer of the amino group to α-ketoglutarate from l-alanine which results in pyruvate and glutamate.Thereby GPT plays a key role in gluconeogenesis and amino acid metabolism. The role of GPT in various kinds of tumors has been reported.
Physical form

Other Notes
One unit will convert 1.0 μmole of α-ketoglutarate to L-glutamate per min at pH 7.6 at 37 °C in the presence of L-alanine.
