Merck, G8255-1KU, Glutamic-Pyruvic Transaminase from porcine heart

General description
Glutamic-pyruvic transaminase (GPT) is localized majorly in the liver.

Research area: Cell Signaling
Application
Glutamic-Pyruvic Transaminase from porcine heart has been used:
in the transamination assay with a racemic mixture of synthetic 3-methyl-2-oxoglutarate
to remove glutamate from the cell culture medium used for culturing human embryonic kidney (HEK293) cells
in the lactate-dehydrogenase (LD)-coupled alanine transaminase (ALT) reaction kinetic studies

Biochem/physiol Actions
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.
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.
