转氨酶或称氨基转换酶(Transaminases;Aminopherases)为广泛存在于生物机体中重要的酶,其作用为催化α—氨基酸与α—酮酸的相互转换反应,使α—氨基酸的α—氨基与α—酮酸的α—酮基发生互换,因此对氨基酸的脱氨作用与机体的中间代谢有着重要的关系。有关转氨酶在生化方面的作用机制,首先由苏联学者 Braunstein 氏在1937—1939年做了详细的研究和正确的阐明。在机体中转氨酶的种类甚多,举凡任何一种氨基酸进行转氨作用 Aminopherases, or aminotransferases (Aminopherases), are important enzymes that are widely found in living organisms. They catalyze the mutual conversion reaction between α-amino acids and α-keto acids, Keto acid α-keto exchange occurs, so the amino acid deamination and the role of the body’s metabolism has an important relationship. On the biochemical aspects of aminotransferase mechanism, first by the Soviet scholar Braunstein in 1937-1939 years made a detailed study and correct elucidation. There are many types of transaminases in the body, such as any kind of amino acid transamination
