Wild-type Human Macaque
Van der Waals −32.30 ± 1.14 −31.35 ± 1.37 −32.53 ± 1.03 0.48
Electrostatic −5.17 ± 1.26 −4.78 ± 2.16 −5.69 ± 1.45 0.81
Polar solvation 23.26 ± 1.71 21.39 ± 0.63 24.03 ± 1.43 0.12
SASA −3.71 ± 0.03 −3.66 ± 0.06 −3.76 ± 0.07 0.18
Binding energy 17.92 ± 0.89 18.4 ± 0.31 17.94 ± 0.1 0.51

Note: The significance difference between the three variants of P. cynomolgi was considered with a p-value less than 0.05. Bold text represents the total binding energy of the protein-ligand complex.
