ENZYME entry: EC 4.1.1.78

Accepted Name
Acetylenedicarboxylate decarboxylase.
Alternative Name(s)
Acetylenedicarboxylate carboxy-lyase.
Acetylenedicarboxylate hydratase.
Reaction catalysed
Acetylenedicarboxylate + H(2)O <=> pyruvate + CO(2)
Comment(s)
  • 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 in its mechanism.
  • Formerly EC 4.2.1.72.
