Subject: AMBER: MM-PBSA problem
Dear Amber users,
Hello there. I encounter a problem in interpreting the results that I got
from MM-PBSA calculation on binding free energy of ligand to my protein.
PBTOT that I got (please refer below) from the calculation is very very
positive (almost impossible), however GBTOT values looks like a more
acceptable value as compared to experimental value. Any ideas on how this
could happen? Any ideas are welcome.
Thanks a lot and hope to hear from you all soon.
