In enzymology an acetylenedicarboxylate decarboxylase (EC 4.1.1.78) is an enzyme that catalyzes the chemical reactionacetylenedicarboxylate + H2O pyruvate + CO2Thus 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).
