5.3.3.21 DELTA3,5-DELTA2,4-dienoyl-CoA isomerase
IUBMB 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.
The enzyme appears in viruses and cellular organisms
