IUBMB Enzyme Nomenclature


Accepted name: L(+)-tartrate dehydratase

Reaction: (R,R)-tartrate = oxaloacetate + H2O

Other name(s): tartrate dehydratase; tartaric acid dehydrase; L-tartrate dehydratase; L-(+)-tartaric acid dehydratase; (R,R)-tartrate hydro-lyase

Systematic name: (R,R)-tartrate hydro-lyase (oxaloacetate-forming)

Comments: The enzyme exists in an inactive low-molecular-mass form, which is converted into active enzyme in the presence of Fe2+ and thiol. cf. EC D(–)-tartrate dehydratase.
