| 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.A form of TDH with two copies of the C-terminal domain is described by . This entry describes a phylogenetically distinct form, which includes the catabolic threonine dehydratase of E. coli; many members are designated as catabolic for this reason. The catabolic form appears to lack a domain. Many members of this family are found in species with other isoleucine biosynthetic enzymes. |
