ID   4.1.1.78
DE   Acetylenedicarboxylate decarboxylase.
AN   Acetylenedicarboxylate carboxy-lyase.
AN   Acetylenedicarboxylate hydratase.
CA   Acetylenedicarboxylate + H(2)O = pyruvate + CO(2).
CC   -!- The mechanism appears to involve hydration of the acetylene and
CC       decarboxylation of the oxaloacetic acid formed, although free
CC       oxaloacetate is not an intermediate.
CC   -!- It is thus analogous to EC 4.2.1.71 in its mechanism.
CC   -!- Formerly EC 4.2.1.72.
