Oxaloacetate tautomerase

In enzymology, an oxaloacetate tautomerase is an enzyme that catalyzes the chemical reaction


 * keto-oxaloacetate $$\rightleftharpoons$$ enol-oxaloacetate

Hence, this enzyme has one substrate, keto-oxaloacetate, and one product, enol-oxaloacetate.

This enzyme belongs to the family of isomerases, specifically those intramolecular oxidoreductases interconverting keto- and enol-groups. The systematic name of this enzyme class is oxaloacetate keto---enol-isomerase. This enzyme is also called oxalacetic keto-enol isomerase.
