[Chimera-users] Fwd: Drug-Protein Interaction

[Elaine Meng]

Hi Kanika,
Take a look at the ViewDock tutorial.  It looks at H-bonds between ligand and receptor using the FindHBond tool.

Another tool that might be useful for this purpose is Find Clashes/Contacts (in menu under Tools... Surface/Binding Analysis):

I also recommend doing the Structure Analysis and Comparison tutorial, which uses distance measurements, FindHBond, Find Clashes/Contacts etc. to examine a binding pocket:

I hope this helps,
Elaine
