The enzyme itaconyl-CoA hydratase () 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 citramalyl-CoA hydro-lyase (itaconyl-CoA-forming). Other names in common use include itaconyl coenzyme A hydratase, and citramalyl-CoA hydro-lyase. This enzyme participates in c5-branched dibasic acid metabolism.
