D-Alanine aminotransferase (EC 2.6.1.21), Bacillus subtilis

D-Alanine aminotransferase (EC 2.6.1.21) is purified from a recombinant E. coli strain. Alanine aminotransferase, formerly known as L-glutamic-pyruvic transaminase, is a pyridoxal phosphate-dependent enzyme present in serum and in various bodily tissues, mainly in the liver. This enzyme catalyses the transfer of an amino group from alanine to alpha-ketoglutarate, thus forming pyruvate and glutamate. Alanine aminotransferase is commonly used as a way of screening for liver problems. In fact, its levels significantly elevated often suggest the existence of viral hepatitis, liver damage or bile duct problems. Following damage to these cells, the enzyme is released into the blood where the level can be measured. The enzyme is provided in 3.2 M ammonium sulphate. Substrate Specificity: Under the reaction conditions specified the enzyme does not present any other detectable enzymatic activities.
