[gmx-users] SAS of ligands

[Marzinek, Jan]

Dear Justin,

Thank you for the link! I know how to calculate it - that is what I am doing. 
Interface AREA = 0.5 (Protein SAS+ 30 Ligands SAS- Protein and 30Ligands SAS)
This is relevant to the situation where ligands do not aggregate.

I my system 22 out of 30 ligands bind to my protein creating two clusters on the terminals of the protein. In this case they cover the area between them. What I think  is that  I have to substract the interface between them from this equation. Am I right?
The question is - how to do this? g_cluster will help?

Thank you.

Jan Marzinek

See the thread from just a few days ago about the same question:
