(a) D1B Receptor-Interaction (2D View) Benazepril is more oriented toward binding sites such as Glu121 and Tyr218. (b) D1B receptor– interaction (3D view) The binding site of benazepril within the D1A receptor is depicted, highlighting the key residues involved in its interaction. The binding pocket is visualized, highlighting its strong interaction through hydrogen bonding and hydrophobic forces.
