Glossary: 3-hydroxypimeloyl-CoA = 3-hydroxy-6-carboxyhexanoyl-CoA
Other name(s): 6-oxocyclohex-1-ene-1-carbonyl-CoA hydrolase; 6-oxocyclohex-1-ene-1-carbonyl-CoA hydrolase (decyclizing)
Systematic name: 6-oxocyclohex-1-ene-1-carbonyl-CoA hydrolase (ring-opening)
Comments: The enzyme, which participates in the anaerobic benzoyl-CoA degradation pathway in certain organisms, catalyses the addition of one molecule of water to the double bound of 6-oxocyclohex-1-ene-1-carbonyl-CoA followed by the hydrolytic C-C cleavage of the alicyclic ring.
