Docked confirmation and hydrogen bond interactions of the hemorphin peptides bound to ACE1 and ACE2. (A) Camel LVVHem6 with ACE1 (B) LVVHem6 with ACE1 (C) Camel LVVHem6 with ACE2 (D) LVVHem6 with ACE2. ACE1 and ACE2 are shown in gray cartoon ribbons and their interacting residues are illustrated in a pink stick display; the docked ligand is shown in yellow and orange stick representation, hydrogen bonds are shown as black dashed lines, salt bridges are shown in red, π–π stacking depicted by light green dashed lines, and π-cation stacking is shown in dark green dashed lines.
