In enzymology, a dodecenoyl-CoA isomerase (EC 5.3.3.8) is an enzyme that catalyzes the chemical reaction
- (3Z)-dodec-3-enoyl-CoA
(2E)-dodec-2-enoyl-CoA
Hence, this enzyme has one substrate, (3Z)-dodec-3-enoyl-CoA, and one product, (2E)-dodec-2-enoyl-CoA.
This enzyme belongs to the family of isomerases, specifically those intramolecular oxidoreductases transposing C=C bonds. The systematic name of this enzyme class is dodecenoyl-CoA (3Z)-(2E)-isomerase. Other names in common use include dodecenoyl-CoA Delta-isomerase, Delta3-cis-Delta2-trans-enoyl-CoA isomerase, acetylene-allene isomerase, dodecenoyl-CoA Delta-isomerase, and dodecenoyl-CoA Delta3-cis-Delta2-trans-isomerase. This enzyme participates in fatty acid metabolism.
