Acetylene hydratase

In enzymology, an acetylene hydratase (EC number|4.2.1.112) is an enzyme that catalyzes the chemical reaction

:acetaldehyde $ightleftharpoons$ 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.
