D(−)-tartrate dehydratase

The enzyme  D (−)-tartrate dehydratase catalyzes the chemical reaction


 * (S,S)-tartrate $$\rightleftharpoons$$ 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 and.
