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.

Dendrimers and dendrons are symmetrically branched polymer structures that possess a well-defined spatial distribution of functional groups. Dendrimers are chemically modified by attaching poly ethylene glycol (PEG) molecule to increase its solubility and prolong circulation half-life."Clickable groups", such as primary acetylenes, are introduced to the mono dispersed dendritic structures, using "click" chemistry. These acetylene groups, attached to Bis-MPA based dendrons, allow it to form the conjugates with bioactive moieties such as carbohydrate, fluorescent dyes, disaccharides etc. Uses: The proposed uses are: as an efficient drug delivery system. in vitro toxicological studies; in vivo via radionuclide labeling and optical imaging biosensors;dip pen nanolithography.
