      Threonine ammonia-lyase, also commonly referred to as threonine deaminase or threonine dehydratase, is an
enzyme responsible for catalyzing the conversion of L-threonine into alpha-ketobutyrate and ammonia. Alpha-ketobutyrate can be converted into L-isoleucine, so threonine ammonia-lyase functions as a key enzyme in BCAA synthesis.It employs a pyridoxal-5’-phosphate cofactor, similar to many enzymes involved in amino acid metabolism. It is found in bacteria, yeast, and plants, though most research to date has focused on forms of the enzyme in bacteria. This enzyme was one of the first in which negative feedback inhibition by the end product of a metabolic pathway was directly observed and studied.The enzyme serves as an excellent example of the regulatory strategies used in amino acid homeostasis. This product with the indicated enzyme activity was briefly purified from engineered E.coli.
