The enzyme lactoyl-CoA dehydratase () catalyzes the chemical reaction
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 lactoyl-CoA hydro-lyase (acryloyl-CoA-forming). Other names in common use include lactoyl coenzyme A dehydratase, lactyl-coenzyme A dehydrase, lactyl CoA dehydratase, acrylyl coenzyme A hydratase, and lactoyl-CoA hydro-lyase. This enzyme participates in propanoate metabolism and styrene degradation.
