Hi,
I am using mm/pbsa to calculate bind energy of protein+ligand complex. Delphi is used to calculate PB value. My question is: Is there any recommendation or preference of which type of charge should be assiged to ligand (I use amber94 for protein) since I found a huge difference of PBCAL value of ligand(~10 kcal) comparing the results from gasteiger charge(for ligand) and AM1 charge(for ligand). Does anyone has the similiar experience? Your suggestion will be highly appreciated!
Thanks in advance.
Nan
