Threonine dehydratase, biosynthetic (IPR005787)

Short name: Thr_deHydtase_biosynth

Family relationships



Threonine dehydratase (EC: (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.

This entry describes a form of threonine dehydratase with two copies of the threonine dehydratase C-terminal domain (IPR001721_. Members with known function participate in isoleucine biosynthesis and are inhibited by isoleucine.
