[ccp4bb] pi-pi R stacking

I'm looking for references where people have tried to at least vaguely quantify the energetics of stacking the guanidinium groups of two R's. I'm looking at 3 cases in protein-protein interfaces, and in each one there's a D or E adjacent, which presumably helps with the charge-charge repulsion. Hi
