Selective inactivation of cytosolic thiolase by 2-alkynoyi-CoA via its intrinsic isomerase activity was studied, which provides an example for rationally developing mechanism-based inhibitors based on a side activity of the enzyme, and may become a supplemental method for better treatment of cardiovascular disease and cancer.

The catalytic domain of the trimeric human Δ3,Δ2‐enoyl‐CoA isomerase, type 2 (HsECI2), has the typical crotonase fold. In the activesite of this fold two main chain NH groups form an oxyanion hole for binding the thioester oxygen of the 3E‐ or 3Z‐enoyl‐CoA substrate molecules. A catalyticglutamate is essential for the proton transfer between the substrate C2 and C4 atoms for forming the product 2E‐enoyl‐CoA
