Accepted name: acetylenedicarboxylate decarboxylase
Reaction: acetylenedicarboxylate + H
O = pyruvate + CO 2 2
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 22.214.171.124 (acetylenecarboxylate hydratase) in its mechanism.
