Native Human Aspartate Aminotransferase

Aspartate Aminotransferase (AST), also known as Glutamate Oxaloacetate Transaminase (GOT), is a pyridoxal phosphate-dependant enzyme which exists in two isoenzymes; mitochondrial and cytosolic forms. The AST enzyme plays an important role in amino acid metabolism and in the urea and tricarboxylic acid cycles. In liver about 80% of the enzyme activity is mitochondrial in origin, whereas in serum the enzyme activity is largely cytosolic. In hepatic disease, serum levels are used to assess liver necrosis and for determining prognosis. In patients with acute Myocardial infarction, measurement of AST isoenzymes provides diagnostic information that differs from that obtained by determination of other marker proteins.
