Aspartate aminotransferase, porcine heart  (Synonyms: EC 2.6.1.1, porcine heart; GOT, porcine heart; AST, porcine heart)

Aspartate aminotransferase (EC 2.6.1.1), porcine heart is a metabolic regulator with the highest activity in the heart, liver and skeletal muscle. Aspartate aminotransferase, porcine heart comprises two isozymes: the cytoplasmic form (AST1) and the mitochondrial form (AST2). By catalyzing reversible transamination reactions between oxaloacetate, L-glutamate and other substances, it is deeply involved in key physiological processes such as amino acid metabolism, the tricarboxylic acid cycle and neurotransmitter synthesis. Aspartate aminotransferase, porcine heart also provides substrate support for the synthesis of urea and purines/pyrimidines. Aspartate aminotransferase, porcine heart is a serum marker reflecting cardiac and hepatic injury, and its abnormal levels are also closely associated with myocardial infarction, cardiovascular diseases and various cancers^[1][2][3].

Aspartate aminotransferase, porcine heart has increased synthesis and release in adipocytes treated with rosiglitazone (HY-17386), which catalyzes the aminotransferase reaction between aspartate and α-ketoglutarate^[1].
