The enzyme cyclohexa-1,5-dienecarbonyl-CoA hydratase (EC 4.2.1.100) catalyzes the chemical reaction
6-hydroxycyclohex-1-enecarbonyl-CoA
⇌
{\displaystyle \rightleftharpoons }
cyclohexa-1,5-dienecarbonyl-CoA + 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 6-hydroxycyclohex-1-enecarbonyl-CoA (cyclohexa-1,5-dienecarbonyl-CoA-forming). Other names in common use include cyclohexa-1,5-diene-1-carbonyl-CoA hydratase, dienoyl-CoA hydratase, and cyclohexa-1,5-dienecarbonyl-CoA hydro-lyase (incorrect). This enzyme participates in benzoate degradation via CoA ligation.
