Oxaloacetase

In enzymology, an oxaloacetase (EC 3.7.1.1) is an enzyme that catalyzes the chemical reaction:^[1]

oxaloacetate + H₂O ${\displaystyle \rightleftharpoons }$ oxalate + acetate

Thus, the two substrates of this enzyme are oxaloacetate and H₂O, whereas its two products are oxalate and acetate.

This enzyme belongs to the family of hydrolases, specifically those acting on carbon-carbon bonds in ketonic substances. The systematic name of this enzyme class is oxaloacetate acetylhydrolase. This enzyme is also called oxalacetic hydrolase.
