  • PubMed Abstract: 
  • The degradation of unsaturated fatty acids is vital to all living organisms. Certain unsaturated fatty acids must be catabolized via a pathway auxiliary to the main beta-oxidation pathway. Dienoyl-coenzyme A (dienoyl-CoA) isomerase catalyzes one step of this auxiliary pathway, the isomerization of 3-trans,5-cis-dienoyl-CoA to 2-trans,4-trans-dienoyl-CoA, and is imported into both mitochondria and peroxisomes ...

    The degradation of unsaturated fatty acids is vital to all living organisms. Certain unsaturated fatty acids must be catabolized via a pathway auxiliary to the main beta-oxidation pathway. Dienoyl-coenzyme A (dienoyl-CoA) isomerase catalyzes one step of this auxiliary pathway, the isomerization of 3-trans,5-cis-dienoyl-CoA to 2-trans,4-trans-dienoyl-CoA, and is imported into both mitochondria and peroxisomes. Dienoyl-CoA isomerase belongs to a family of CoA-binding proteins that share the enoyl-CoA hydratase/isomerase sequence motif.
