Acetylene hydratase

In enzymology, an acetylene hydratase is an enzyme that catalyzes the chemical reaction


 * acetaldehyde $$\rightleftharpoons$$ acetylene + H2O

Hence, this enzyme has one substrate, acetaldehyde, and two products, acetylene and H2O.

This enzyme belongs to the family of lyases, specifically the hydro-lyases, which cleave carbon-oxygen bonds. The systematic name of this enzyme class is acetaldehyde hydro-lyase (acetylene-forming). Other names in common use include AH, and acetaldehyde hydro-lyase. This enzyme participates in tetrachloroethene degradation.
