>TIGR01127 ilvA_1Cterm threonine dehydratase; InterPro: IPR005789 Serine and threonine dehydratases , are functionally and structurally related pyridoxal-phosphate dependent enzymes. L-serine dehydratase () and D-serine dehydratase () catalyze the dehydratation of L-serine (respectively D-serine) into ammonia and pyruvate. Threonine dehydratase () (TDH) catalyzes the dehydratation of threonine into alpha-ketobutarate and ammonia. In Escherichia coli and other microorganisms, two classes of TDH are known to exist. One is involved in the biosynthesis of isoleucine, the other in hydroxamino acid catabolism. Threonine synthase () is also a pyridoxal-phosphate enzyme, it catalyzes the transformation of homoserine-phosphate into threonine. It has been shown that threonine synthase is distantly related to the serine/threonine dehydratases. In all these enzymes, the pyridoxal-phosphate group is attached to a lysine residue. A form of threonine dehydratase with two copies of the C-terminal domain is described by . This model describes a phylogenetically distinct which branches with the catabolic threonine dehydratase of E. coli; many members are designated as catabolic for this reason. However, the catabolic form lacks any domain. Many members of this model are found in species with other isoleucine biosynthetic enzymes.; GO: 0004794 L-threonine ammonia-lyase activity.
