How to for selecting protein: Pick a protein with few substrates and rotational bonds?
The PDB code chosen is 6UZW which is for the crystal structure of GLUN1/GLUN2A ligand-binding domain in complex with glycine and UBP791.
Dock Prep Program used: Chimera
Step 1. Separate protein and ligand
Step 2. Delete H2O molecules in Chimera to reduce computing time.
- To delete: Select > Residues > H O H - they should be highlighted Click Actions > Atoms/Bonds > delete H2O molecules should now be deleted.
Step 3. Add H's.
- PDB codes do not contain H's due to low electron density.
- To add H's Tools > Structure Editing > AddH
- H's MUST be added before you add charge or they will not be accounted for and will affect predictions for interactions.
Step 4. Add charge.
- Add charges Tools > Structure Editing > Add charge Typically use AM1-BCC
- You need to be careful about selecting charge because this will affect predictions for interactions (i.e. Coulomb's Law). Read paper corresponding to your PDB stucture to determine conditions of purification and proper protonation. In the case of 6UZW our paper of reference is: https://doi.org/10.1038/s41467-020-14321-0
