I know little of the apbs-pymol integration, but in general, you can use the PROPKA support built into PDB2PQR to assign protonation at different pHs and then feed your pqr to apbs.
See http://www.poissonboltzmann.org/pdb2pqr/user-guide/using-pdb2pqr for the --with-ph option. There's also a whole different world of using apbs to determine pKa (see http://www.poissonboltzmann.org/apbs/examples/pka-calculations ) -David On Wed, Apr 7, 2010 at 12:49 PM, Soisson, Stephen M <stephen_sois...@merck.com> wrote: > Hi- > > Does anyone know if it is possible to calculate the charged surface using > apbs at different pHs?
