The enzyme <small>D</small>(âÂÂ)-tartrate dehydratase () catalyzes the chemical reaction
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 <small>D</small>-tartrate dehydratase, and (S,S)-tartrate hydro-lyase. It has 2 cofactors: iron and manganese.
As of late 2007, two structures have been solved for this class of enzymes, with PDB accession codes and .
