Image Aspartate transaminase.png thumb right 300px Aspartatetransaminase from E. coli with Pyridoxal 5 Phosphate cofactor In biochemistry , a transaminase or an aminotransferase is an enzyme that catalyze s a type of reaction between an amino acid and an alpha keto acid &alpha keto acid . To be specific, this reaction transamination involves removing the amino group from the amino acid, leaving behind an keto acid, and transferring it to the reactant keto acid and converting it into an amino acid. The enzymes are important in the production of various amino acids, and measuring the concentration s of various transaminases in the blood is important in the diagnosing and tracking many disease s. Transaminases require the coenzyme pyridoxal phosphate , which is converted into pyridoxamine in the first phase of the reaction, when an amino acid is converted into a keto acid. Enzyme bound pyridoxamine in turn reacts with pyruvate , oxaloacetate , or alpha ketoglutarate , giving alanine , aspartic acid , or glutamic acid , respectively. The presence of elevated transaminases can be an indicator of liver damage. Transaminases in amino acid metabolism in animals Animals must metabolize proteins to amino acids, at the expense of muscle tissue, when blood sugar is low. The preference of liver transaminases for oxaloacetate or alpha ketoglutarate plays a key role in funneling nitrogen from amino acid metabolism to aspartate and glutamate for conversion to urea for excretion of nitrogen. In similar manner, in muscles the use of pyruvate for transamination gives alanine, which is carried by the bloodstream to the liver the overall reaction being termed Alanine cycle glucose alanine ....
