Oct-2-yn-4-enoyl-CoA as a multifunctional enzyme inhibitor in fatty acid oxidation.

Oct-2-yn-4-enoyl-CoA was found to be a multifunctional irreversible enzyme inhibitor in fatty acid oxidation mainly targeting mitochondrial trifunctional protein beta-subunit. It can also inactivate enoyl-CoA hydratase 2 and medium-chain acyl-CoA dehydrogenase. This study increased our understanding for the effect of acetylenic acids on fatty acid oxidation.
