Hi Mateus. No, I was certainly not aware of BioPython. What a nice project. I will check it out.
No, the script should not download a .pdb file. The idea is, that a "researcher/student" sits with his/hers favorite protein in pymol and would like to know the pKa value of his/hers favorite amino acids. The student "probably" has only pymol installed, and would not like to install to many other python packages. Maybe the student can't, because it is a university computer. With this web-interaction script, the students activate the script, with: get_pka Molecule, residue The script saves the molecule to a .pdb file. Interact with the propka web site, send the file, wait 1 minute, grep for the line with the amino acid, and parse it back to pymol, so the student can see the pKa. To big benefit with this, is that the student does not have to handle to hard installations of scripts/programs or the manual way. And the student knows, that the pKa prediction is from the newest software available. If the student get greedy, he/she starts writing a pymol script that alter the pdb structure in pymol, and receive the new pKa value for each structural change. The downside, is of course the "waiting" time for the server response.
