Hello all,
My system includes a protein and a ligand. I tried to use mm_pbsa to
calculate binding energy of the ligand to the protein. I manually added 8
water molecules in the pdb file before I used tleap to add water cap. Then
mmpbsa calculation seems to include those manually added 8 waters in the
calculation.
The reason I added waters in addition to tleap water cap is that those
waters mediates interaction between ligand and protein and tleap cannot add
water to those 8 positions.
Do anyone has similar experience? A more general question is how to include
water molecules as part of protein to calculate binding energy using mmpbsa?
Thank you in advance for your assistance.
Yong
