Subject: AMBER: Ligand from CCDC.

I was wondering about a ligand. I have built a small molecule (Isobutyramide)in Xleap to be docked in a protein. Then I went for MD for calculeting binding energy. The energy seems to be 7-8 kcal/mol higher then the experimental value. I used the LIE method for energy determination.

The X-ray structure for Iso butyramide is also available in CCDC.I sent an e-mail to them to get the sructure.But the file seems to strange looking.

My questions are:
1.Can I get relatively better interaction energy with CCDC structure?
2. How can I convert the CCDC structure to an AMBER readable format?

I will appreciate your answere.
