| description | 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 involvedin the biosynthesis of isoleucine, the other in hydroxamino acid catabolism.This entry describes a form of TDH that is distinct from the clades described by and . The sequences described by this entry have one copy of the threonine dehydratase C-terminal domain (). They are exclusively found in species containing the rest of the isoleucine biosynthesis pathway and which are generally lacking in members of the other two clades of threonine dehydratases. They include mitochondrial and plastid threonine dehydratases. |
