Reaction: acetylenedicarboxylate + H2O = pyruvate + CO2
Other name(s): acetylenedicarboxylate hydratase; acetylenedicarboxylate hydrase; cetylenedicarboxylate carboxy-lyase
Systematic name: acetylenedicarboxylate carboxy-lyase (pyruvate-forming)
Comments: 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 22.214.171.124 (acetylenecarboxylate hydratase) in its mechanism. Formerly EC 126.96.36.199
