Oxalate decarboxylase

In enzymology, an oxalate decarboxylase is an enzyme that catalyzes the chemical reaction


 * oxalate + H+ $$\rightleftharpoons$$ formate + CO2

Thus, the two substrates of this enzyme are oxalate and H+, whereas its two products are formate and CO2.

This enzyme belongs to the family of lyases, specifically the carboxy-lyases, which cleave carbon-carbon bonds. The systematic name of this enzyme class is oxalate carboxy-lyase (formate-forming). This enzyme is also called oxalate carboxy-lyase. This enzyme participates in glyoxylate and dicarboxylate metabolism.
