Abstract
The occurrence of acrylamide is frequently observed in processed foods. Therefore, the harmful effects of acrylamide on metabolic enzymes are important to understand. We studied the inhibitory effects of acrylamide on the brain creatine kinase (CK-BB). We found that CK-BB was kinetically inactivated by acrylamide accompanied by the disruption of the hydrophobic surface. Acrylamide mainly interacted with the thiol (–SH) residue of CK-BB and resulted in alkylation. A computational docking simulation supported that acrylamide directly bound to the active site of CK-BB where cysteine and glycine residues interacted mainly. The inhibition kinetics combined with computational prediction can be useful in order to have insights into the mechanisms regarding environmentally hazardous factors at the molecular level.
