The reaction is effectively irreversible, favouring oxopropanoate (malonic semialdehyde) and its tautomers. Also acts on but-3-ynoate forming acetoacetate. The mechanism appears to involve hydration of the acetylene to 3-hydroxypropenoate, which will spontaneously tautomerize to 3-oxopropanoate. It is thus analogous to EC 4.1.1.78, acetylenedicarboxylate decarboxylase, in its mechanism. Group: Enzymes. Synonyms: acetylenemonocarboxylate hydratase; alkynoate hydratase; acetylenemonocarboxylate hydrase; acetylenemonocarboxylic acid hydrase; malonate-semialdehyde dehydratase; 3-oxopropanoate hydro-lyase. Enzyme Commission Number: EC 4.2.1.27. CAS No. 9024-26-4. Storage: Store it at +4 ?C for short term. For long term storage, store it at -20 ?C?-80 ?C. Form: Liquid or lyophilized powder. EXWM-5018; acetylenecarboxylate hydratase; EC 4.2.1.27; 9024-26-4; acetylenemonocarboxylate hydratase; alkynoate hydratase; acetylenemonocarboxylate hydrase; acetylenemonocarboxylic acid hydrase; malonate-semialdehyde dehydratase; 3-oxopropanoate hydro-lyase. Cat No: EXWM-5018.
acetylenedicarboxylate decarboxylase
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 4.2.1.27 (acetylenecarboxylate hydratase) in its mechanism. Group: Enzymes. Synonyms: acetylenedicarboxylate hydratase; acetylenedicarboxylate hydrase; acetylenedicarboxylate carboxy-lyase. Enzyme Commission Number: EC 4.1.1.78. CAS No. 72561-10-5.
