We addressed some of these electrostatics problems (Xray artefact like presence of ions, crystal packing, etc) a long time ago. Feel free to look at: Improving macromolecular electrostatics calculations. Nielsen JE, Andersen KV, Honig B, Hooft RW, Klebe G, Vriend G, Wade RC. Protein Eng. 1999

Dear users.I'm comparing surface charge of a structure with its homologous (85% seq ID), and noted that APBS suggest completely opposite charge distribution (exactly what I expected, since despite its similarity molecules have opposite biochemical profile) But since molecules are quite

Why not ? Look at the partner protein is there a similar charge reversal present? The function is preserved (interaction of both proteins) in different species but the charges have swapped over time in evolution while the backbone scaffold (fold) of the protein was maintained. Just as an

Dear CCP4BB, I apologize for the off topic question. I have determined the 3D structure of a membrane protein transporter and want to make a figure showing the surface charge. So, I ran PDB2PQR and specified pH 5.4. I understand the next step is to run APBS. I know there are different
