2. select the protein intereted (Figure 1. step 4).
3. pick a atom, single click button Run (Figure 1. step 5 and 6).
Figure 1. Five steps to use the script
This section will introduce how to calculate the ΔGwatdisp for ligands 9s and 9z.
Enter the following command in the shell:
gist_dG_watdisp.py -g 5c29_apo_gist_dG.dx -i 9s-9z.sdf -o 9s-9z_out.sdf
You can find the GIST-dG-Watdisp tag in the output SDF file, which represents the calculated ΔGwatdisp. You can find the calculation results for 9s as follows:
> <GIST-dG-Watdisp> (1)
-41.599
And ΔGwatdisp for 9z as follows:
> <GIST-dG-Watdisp> (2)
-38.223
Thus, the ΔΔGwatdisp between 9s and 9z is 3.38 kcal/mol, which is very close to the difference in their binding free energies (ΔΔG = 3.44 kcal/mol).
rdkit, numpy and GridDataFormats are required.
