In enzymology, a L(+)-tartrate dehydratase (EC 4.2.1.32) is an enzyme that catalyzes the chemical reaction

(R,R)-tartrate oxaloacetate + H2O

Hence, this enzyme has one substrate, (R,R)-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 (R,R)-tartrate hydro-lyase (oxaloacetate-forming). Other names in common use include tartrate dehydratase, tartaric acid dehydrase, L-tartrate dehydratase, L-(+)-tartaric acid dehydratase, and (R,R)-tartrate hydro-lyase. This enzyme participates in glyoxylate and dicarboxylate metabolism. It has 2 cofactors: iron, and Thiol.
