Accepted name: Δ3,52,4-dienoyl-CoA isomerase
Reaction: a (3E,5Z)-alka-3,5-dienoyl-CoA = a (2E,4E)-alka-2,4-dienoyl-CoA
Other name(s): 3,5-tetradecadienoyl-CoA isomerase; DCI1 (gene name)
Systematic name: (3E,5Z)-alka-3,5-dienoyl-CoA Δ3,52,4 isomerase
Comments: The enzyme participates in an alternative degradation route of fatty acids with cis-double bonds on odd-number carbons such as oleate and linoleate. The main physiological substrate is (3E,5Z)-tetradeca-3,5-dienoyl-CoA, but other (3E,5Z)-dienoyl-CoAs with varying carbon chain lengths are also substrates.
