Accepted name: acetylenedicarboxylate decarboxylase
Reaction: acetylenedicarboxylate + H2O = pyruvate + CO2
Other name(s): acetylenedicarboxylate hydratase; acetylenedicarboxylate hydrase; acetylenedicarboxylate 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 (acetylenecarboxylate hydratase) in its mechanism.
