Figure 4. — Docking results of the hVKOR homology model with different ligands. The binding site of NAPQI, NAC and acetaminophen in the ribbon view ((A), (B), and (C), respectively), and interacting amino acids diagrams showing the amino acids and chemical bonds involved in the interaction of NAPQI, NAC, and acetaminophen with hVKOR homology model in two dimensional view ((D), (E), and (F), respectively). Superposition of ligands is shown in (G). hVKOR, gray ribbon; NAPQI, red stick; NAC; cyan stick; acetaminophen, magnetic stick, red semi-circle radial spikes: hydrophobic interaction; sky blue dash lines: hydrogen bond.
