The enzyme D(−)-tartrate dehydratase (EC 4.2.1.81) catalyzes the chemical reaction
- (S,S)-tartrate [math]\displaystyle{ \rightleftharpoons }[/math] oxaloacetate + 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.
