The mechanism appears to involve hydration of the acetylene and decarboxylation of the oxaloacetic acid formed, although free oxaloacetate is not an intermediate. It is thus analogous to EC 4.2.1.27 (acetylenecarboxylate hydratase) in its mechanism.

acetylenedicarboxylate + H2O = pyruvate + CO2
the mechanism appears to involve hydration of the acetylene and decarboxylation of the oxaloacetic acid formed, although free oxaloacetate is not an intermediate. It is thus analogous to EC 4.2.1.71, acetylenecarboxylate hydratase, in its mechanism. Formerly EC 4.2.1.72
