Therefore, we discovered that the ligand interacted predominantly together with the amino acids from the secondary components on the T7 loop, H8 helix, and S9 sheet of CBS. The kinds of non-covalent interactions with these amino acids, which includes the formation of hydrogen, hydrophobic, ionic interactions, and the formation of water bridges, too as the contribution of every interaction form for the all round interaction using a unique amino acid, are shown within the Figures 8A and 9. The time-dependent total number of contacts involving the ligand and protein and the number of contacts among the ligand and distinct amino acids are shown in Figure 8B.Molecules 2022, 27, x FOR PEER REVIEW11 ofMolecules 2022, 27,trajectory evaluation showed the low RMSD values on the ligands and proteins (Figure 7), which indicates the absence of massive fluctuations throughout the whole time of molecular dynamics.11 ofMolecules 2022, 27, x FOR PEER Critique Figure 7.

For that reason, we identified that the ligand interacted predominantly with the amino acids of the secondary elements with the T7 loop, H8 helix, and S9 sheet of CBS. The varieties of non-covalent interactions with these amino acids, including the formation of hydrogen, hydrophobic, ionic interactions, and the formation of water bridges, also as the contribution of every interaction type towards the all round interaction with a specific amino acid, are shown in the Figures 8A and 9. The time-dependent total quantity of contacts amongst the ligand and protein along with the variety of contacts in between the ligand and specific amino acids are shown in Figure 8B.Figure eight.
