Ochratoxin (OTA)—bromelain interactions. (A) Detailed view showing the interactions of the different amino acid residues within the binding pocket of bromelain with the OTA ligand. (B) Panoramic view of the reference (E64) and the tested OTA ligands within the binding pocket of bromelain. Comparison between the docked pose of the tested and the reference ligand within the bromelain binding pocket. The yellow arrow indicates the proximity between the bromelain catalytic triad and the OTA amide bond, suggesting its breakup.
