Preparation of the protein input files for PLANTS

The program PLANTS needs a .mol2 protein file format thus our procedure protonates the uploaded .pdb structure file by using the program PDBPQR (version 1.6; ref1) with AMBER forcefield option. Then, the pdb file is converted into a .mol2 file format.

 Protonate the protein and convert it into .mol2 file
  • Protein structure file in pdb format:  
  • (option) Create a binding site input file around a residue or a ligand in the pdb structure:

    RESIDUE name (case sensitive)   RESIDUE number   CHAIN (or leave empty)

    or set coordinates of the center of the binding site: x ,   y ,   z

    Binding site radius

  •  or simply convert a protein .pdb file into .mol2 file
  • Protein structure file in pdb format  

    The residue naming scheme must be of AMBER type; the protonation step is skipped
