The all round outcomes of your molecular dynamics showed that all three compounds were stable and interacted with the protein in the course of the simulation period. These results had been quite nicely correlated with all the results from the molecular docking.R PEERMolecules 2021, 26, 4147 REVIEW15 ofFigure 7.

Molecular Interaction of Ligands with Amino Acids on the Target Protein Furthermore, we wanted to find out when the lead compounds and STa share exactly the same binding website in terms of amino acid residues on ECD. This necessary the identification of the amino acid residues on ECD interacting and binding with STa. It can be worth mentioning right here that Wada et al. (1996) [35], making use of site directed mutagenesis, showed ARG136 and ASP347 to become amino acid residues binding to STa within the extracellular domain of pigStaR. They also suggested that a area from ASP347 to Val 401, close to the transmembrane domain, is essential for STa binding activity and guanylyl cyclase catalytic activity. Hasegawa et al. (1999) [71] designed a photoaffinity labelled analog of STa and used it for the identification on the ligand binding web-site around the extracellular surface of GC-C. They reported the ligand binding area involving 387 to residue 393 on ECD. Within the present study we attempted to investigate the binding of STa on a modelled structure of ECD applying an in silico approach. We performed the docking of STa.
