I used the HPEPDOCK server (http:// huanglab.phys.hust.edu.cn/hpepdock /) to dock a ligand onto a receptor and downloaded the conformation (pose) of the ligand with lowest energy.

Next I opened the receptor and ligand structure in UCSF chimera. The ligand fitted perfectly in the binding site.

Now is it possible to know which residues of the ligand are interacting with the receptor and what is the type of non-covalent interaction between them?

Thanks in advance,
