In enzymology, a D(-)-tartrate dehydratase (EC 4.2.1.81) is an enzyme that catalyzes the chemical reaction

(S,S)-tartrate \rightleftharpoons oxaloacetate + H2O

Hence, this enzyme has one substrate, (S,S)-tartrate, and two products, oxaloacetate and H2O.

This enzyme belongs to the family of lyases, specifically the hydro-lyases, which cleave carbon-oxygen bonds. The systematic name of this enzyme class is (S,S)-tartrate hydro-lyase (oxaloacetate-forming). Other names in common use include D-tartrate dehydratase, and (S,S)-tartrate hydro-lyase. It has 2 cofactors: iron, and Manganese.

Structural studies

As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes 2DW6 and 2DW7.
