Thus, the two substrates of this enzyme are acetylenedicarboxylate and H2O, whereas its two products are pyruvate 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 acetylenedicarboxylate carboxy-lyase (pyruvate-forming). Other names in common use include acetylenedicarboxylate hydratase, acetylenedicarboxylate hydrase, and acetylenedicarboxylate carboxy-lyase. This enzyme participates in pyruvate metabolism.
